Batteries are a kind of energy conversion and storage devices that convert chemical or physical energy into electrical energy through reactions. According to the different energy conversion of the battery, the battery can be divided into a chemical battery and a biological battery. A chemical battery or chemical power source is a device that converts chemical energy into electrical energy. It comprises two electrochemically active electrodes with different components, respectively, composed of positive and negative electrodes. A chemical substance that can provide media conduction is used as an electrolyte. When connected to an external carrier, it delivers electrical energy by converting its internal chemical energy. A physical battery is a device that converts physical energy into electrical energy.

Is é an príomh-difríocht ná go bhfuil an t-ábhar gníomhach difriúil. Tá ábhar gníomhach na ceallraí tánaisteacha inchúlaithe, cé nach bhfuil ábhar gníomhach na ceallraí príomhúla. Tá féin-urscaoileadh na ceallraí príomhúla i bhfad níos lú ná sin na ceallraí tánaisteacha. Mar sin féin, tá an fhriotaíocht inmheánach i bhfad níos mó ná an ceallraí tánaisteach, agus mar sin tá an cumas ualaigh níos ísle. Ina theannta sin, tá cumas mais-shonrach agus cumas toirt-shonrach na ceallraí príomhúla níos suntasaí ná iad siúd atá ag cadhnraí in-athluchtaithe atá ar fáil.

Ni-MH batteries use Ni oxide as the positive electrode, hydrogen storage metal as the negative electrode, and lye (mainly KOH) as the electrolyte. When the nickel-hydrogen battery is charged: Positive electrode reaction: Ni(OH)2 + OH- → NiOOH + H2O–e- Adverse electrode reaction: M+H2O +e-→ MH+ OH- When the Ni-MH battery is discharged: Positive electrode reaction: NiOOH + H2O + e- → Ni(OH)2 + OH- Negative electrode reaction: MH+ OH- →M+H2O +e-

The main component of the positive electrode of the lithium-ion battery is LiCoO2, and the negative electrode is mainly C. When charging, Positive electrode reaction: LiCoO2 → Li1-xCoO2 + xLi+ + xe- Negative reaction: C + xLi+ + xe- → CLix Total battery reaction: LiCoO2 + C → Li1-xCoO2 + CLix The reverse reaction of the above reaction occurs during discharge.

Commonly used IEC standards for batteries: The standard for nickel-metal hydride batteries is IEC61951-2: 2003; the lithium-ion battery industry generally follows UL or national standards. Commonly used national standards for batteries: The standards for nickel-metal hydride batteries are GB/T15100_1994, GB/T18288_2000; the standards for lithium batteries are GB/T10077_1998, YD/T998_1999, and GB/T18287_2000. In addition, the commonly used standards for batteries also include the Japanese Industrial Standard JIS C on batteries. IEC, the International Electrical Commission (International Electrical Commission), is a worldwide standardization organization composed of electrical committees of various countries. Its purpose is to promote the standardization of the world's electrical and electronic fields. IEC standards are standards formulated by the International Electrotechnical Commission.

Is iad príomh-chomhpháirteanna cadhnraí hidríde nicil-mhiotail ná bileog leictreoid dhearfach (ocsaíd nicil), bileog leictreoid diúltach (cóimhiotal stórála hidrigine), leictrilít (go príomha KOH), páipéar scairt, fáinne séalaithe, caipín leictreoid dhearfach, cás ceallraí, etc.

Is iad príomhchodanna cadhnraí litiam-ian clúdaigh ceallraí uachtaracha agus íochtaracha, bileog leictreoid dhearfach (is é ábhar gníomhach ocsaíd cóbalt litiam), deighilteoir (membrane ilchodach speisialta), leictreoid diúltach (is é ábhar gníomhach carbóin), leictrilít orgánach, cás ceallraí. (roinnte ina dhá chineál bhlaosc cruach agus bhlaosc alúmanaim) agus mar sin de.

Tagraíonn sé don fhriotaíocht a bhíonn ag an sruth ag sreabhadh tríd an gceallraí nuair a bhíonn an ceallraí ag obair. Tá sé comhdhéanta de fhriotaíocht inmheánach ohmic agus friotaíocht inmheánach polaraithe. Laghdóidh friotaíocht suntasach inmheánach na ceallraí an voltas oibre urscaoilte ceallraí agus laghdóidh sé an t-am urscaoilte. Is é an t-ábhar ceallraí, próiseas déantúsaíochta, struchtúr ceallraí, agus fachtóirí eile a théann i bhfeidhm ar fhriotaíocht inmheánach go príomha. Is paraiméadar tábhachtach é feidhmíocht ceallraí a thomhas. Nóta: Go ginearálta, is é an friotaíocht inmheánach sa stát muirearaithe an caighdeán. Chun friotaíocht inmheánach na ceallraí a ríomh, ba cheart go n-úsáidfeadh sé méadar friotaíochta inmheánach speisialta in ionad multimeter sa raon ohm.

Tagraíonn voltas ainmniúil na ceallraí don voltas a thaispeántar le linn oibriú rialta. Is é voltas ainmniúil na ceallraí tánaisteach nicil-caidmiam nicil-hidrigine ná 1.2V; is é 3.6V voltas ainmniúil na ceallraí litiam tánaisteacha.

Tagraíonn voltas ciorcad oscailte don difríocht ionchasach idir leictreoidí dearfacha agus diúltacha na ceallraí nuair nach bhfuil an ceallraí ag obair, is é sin, nuair nach bhfuil aon sruth ag sreabhadh tríd an gciorcad. Tagraíonn voltas oibre, ar a dtugtar voltas críochfoirt freisin, don difríocht ionchasach idir cuaillí dearfacha agus diúltacha na ceallraí nuair a bhíonn an ceallraí ag obair, is é sin, nuair a bhíonn forshrutha sa chiorcad.

Tá cumas na ceallraí roinnte sa chumhacht rátáilte agus an cumas iarbhír. Tagraíonn cumas rátáilte na ceallraí don choinníoll nó don ráthaíocht gur cheart don cheallraí an t-íosmhéid leictreachais a urscaoileadh faoi choinníollacha urscaoilte áirithe le linn dearadh agus déantúsaíocht na stoirme. Sonraíonn an caighdeán IEC go ngearrtar cadhnraí nicil-caidmiam agus hidríde nicil-mhiotail ag 0.1C ar feadh 16 uair an chloig agus go ndéantar iad a urscaoileadh ag 0.2C go 1.0V ag teocht 20°C±5°C. Cuirtear toilleadh rátáilte na ceallraí in iúl mar C5. Tá sé ordaithe cadhnraí litiam-ian a mhuirearú ar feadh 3 uair an chloig faoi mheánteocht, rialú reatha tairiseach (1C) - voltas seasmhach (4.2V) coinníollacha éilitheacha, agus ansin urscaoileadh ag 0.2C go 2.75V nuair a bhíonn an leictreachas urscaoilte cumas rátáilte. Tagraíonn cumas iarbhír na ceallraí don fhíor-chumhacht a scaoileann an stoirm faoi choinníollacha urscaoilte áirithe, a bhfuil tionchar aige go príomha ar an ráta urscaoilte agus teocht (mar sin go docht ag labhairt, ba cheart go sonródh acmhainn na ceallraí na coinníollacha muirir agus urscaoilte). Is é an t-aonad cumais ceallraí Ah, mAh (1Ah = 1000mAh).

Nuair a bhíonn an ceallraí rechargeable urscaoileadh le sruth mór (cosúil le 1C nó níos airde), mar gheall ar an "éifeacht bac" atá ann cheana féin i ráta idirleathadh inmheánach an forshrutha reatha, tá an ceallraí tar éis an voltas teirminéil a bhaint amach nuair nach bhfuil an acmhainn urscaoilte go hiomlán. , agus ansin úsáideann sruth beag ar nós 0.2C is féidir leanúint ar aghaidh a bhaint, go dtí 1.0V/píosa (níicil-caidmiam agus nicil-hidrigine ceallraí) agus 3.0V/píosa (ceallraí litiam), tá an acmhainn a scaoileadh ar a dtugtar acmhainn iarmharach.

Tagraíonn ardán urscaoilte cadhnraí Ni-MH in-athluchtaithe de ghnáth don raon voltais ina bhfuil voltas oibre na ceallraí sách cobhsaí nuair a dhéantar é a urscaoileadh faoi chóras urscaoilte ar leith. Baineann a luach leis an sruth urscaoilte. Dá mhéad an sruth, is ísle an meáchan. Is é an t-ardán urscaoilte cadhnraí litiam-ian go ginearálta ná stop a mhuirearú nuair a bhíonn an voltas 4.2V, agus an láthair níos lú ná 0.01C ag voltas leanúnach, ansin é a fhágáil ar feadh 10 nóiméad, agus é a urscaoileadh go 3.6V ag aon ráta urscaoilte. reatha.

Sonraítear i gcaighdeán idirnáisiúnta IEC gurb é an gnáth-mhuirearú agus urscaoileadh cadhnraí hidríde nicil-mhiotail: an ceallraí a urscaoileadh ar dtús ag 0.2C go 1.0V/píosa, ansin muirear ag 0.1C ar feadh 16 uair an chloig, é a fhágáil ar feadh 1 uair an chloig, agus é a chur. ag 0.2C go 1.0V/píosa, is é sin an caighdeán ceallraí a mhuirearú agus a urscaoileadh.

Go ginearálta úsáideann muirearú pulse muirearú agus urscaoileadh, ag socrú ar feadh 5 soicind agus ansin ag scaoileadh ar feadh 1 soicind. Laghdóidh sé an chuid is mó den ocsaigin a ghintear le linn an phróisis mhuirearaithe go electrolytes faoin gcuisle urscaoilte. Ní hamháin go gcuireann sé teorainn le méid galúcháin inmheánach leictrilít, ach déanfaidh na sean-chadhnraí sin a ndearnadh polarú mór orthu a ghnóthú de réir a chéile nó dul i ngleic leis an gcumas bunaidh tar éis 5-10 uair a mhuirearú agus a urscaoileadh ag baint úsáide as an modh muirir seo.

Úsáidtear muirearú trickle chun cúiteamh a dhéanamh ar an gcaillteanas acmhainne de bharr féin-urscaoileadh na ceallraí tar éis é a mhuirearú go hiomlán. Go ginearálta, úsáidtear luchtú reatha pulse chun an cuspóir thuas a bhaint amach.

Tagraíonn éifeachtúlacht muirir do thomhas ar an méid a dhéantar an fuinneamh leictreach a ídíonn an ceallraí le linn an phróisis muirir a thiontú go fuinneamh ceimiceach is féidir leis an gceallraí a stóráil. Is é an teicneolaíocht ceallraí agus teocht timpeallachta oibre na stoirme a théann i bhfeidhm go príomha air - go ginearálta, dá airde an teocht chomhthimpeallach, is lú an éifeachtúlacht muirir.

Tagraíonn éifeachtacht urscaoilte don chumhacht iarbhír a urscaoileadh chuig an voltas críochfoirt faoi choinníollacha urscaoilte áirithe chuig an acmhainn rátáilte. Tá tionchar aige go príomha ar an ráta urscaoilte, teocht chomhthimpeallach, friotaíocht inmheánach, agus fachtóirí eile. Go ginearálta, dá airde an ráta urscaoilte, is airde an ráta urscaoilte. Dá ísle an éifeachtacht urscaoilte. Dá ísle an teocht, is ísle an éifeachtúlacht urscaoilte.

The output power of a battery refers to the ability to output energy per unit time. It is calculated based on the discharge current I and the discharge voltage, P=U*I, the unit is watts. The lower the internal resistance of the battery, the higher the output power. The internal resistance of the battery should be less than the internal resistance of the electrical appliance. Otherwise, the battery itself consumes more power than the electrical appliance, which is uneconomical and may damage the battery.

Self-discharge is also called charge retention capability, which refers to the retention capability of the battery's stored power under certain environmental conditions in an open circuit state. Generally speaking, self-discharge is mainly affected by manufacturing processes, materials, and storage conditions. Self-discharge is one of the main parameters to measure battery performance. Generally speaking, the lower the storage temperature of the battery, the lower the self-discharge rate, but it should also note that the temperature is too low or too high, which may damage the battery and become unusable. After the battery is fully charged and left open for some time, a certain degree of self-discharge is average. The IEC standard stipulates that after fully charged, Ni-MH batteries should be left open for 28 days at a temperature of 20℃±5℃ and humidity of (65±20)%, and the 0.2C discharge capacity will reach 60% of the initial total.

The self-discharge test of lithium battery is: Generally, 24-hour self-discharge is used to test its charge retention capacity quickly. The battery is discharged at 0.2C to 3.0V, constant current. Constant voltage is charged to 4.2V, cut-off current: 10mA, after 15 minutes of storage, discharge at 1C to 3.0 V test its discharge capacity C1, then set the battery with constant current and constant voltage 1C to 4.2V, cut-off current: 10mA, and measure 1C capacity C2 after being left for 24 hours. C2/C1*100% should be more significant than 99%.

The internal resistance in the charged state refers to the internal resistance when the battery is 100% fully charged; the internal resistance in the discharged state refers to the internal resistance after the battery is fully discharged. Generally speaking, the internal resistance in the discharged state is not stable and is too large. The internal resistance in the charged state is more minor, and the resistance value is relatively stable. During the battery's use, only the charged state's internal resistance is of practical significance. In the later period of the battery's help, due to the exhaustion of the electrolyte and the reduction of the activity of internal chemical substances, the battery's internal resistance will increase to varying degrees.

Is é an friotaíocht inmheánach statach friotaíocht inmheánach na ceallraí le linn an urscaoilte, agus is é an fhriotaíocht inmheánach dinimiciúil friotaíocht inmheánach na ceallraí le linn muirir.

The IEC stipulates that the standard overcharge test for nickel-metal hydride batteries is: Discharge the battery at 0.2C to 1.0V/piece, and charge it continuously at 0.1C for 48 hours. The battery should have no deformation or leakage. After overcharge, the discharge time from 0.2C to 1.0V should be more than 5 hours.

IEC stipulates that the standard cycle life test of nickel-metal hydride batteries is: After the battery is placed at 0.2C to 1.0V/pc 01) Charge at 0.1C for 16 hours, then discharge at 0.2C for 2 hours and 30 minutes (one cycle) 02) Charge at 0.25C for 3 hours and 10 minutes, and discharge at 0.25C for 2 hours and 20 minutes (2-48 cycles) 03) Charge at 0.25C for 3 hours and 10 minutes, and release to 1.0V at 0.25C (49th cycle) 04) Charge at 0.1C for 16 hours, put it aside for 1 hour, discharge at 0.2C to 1.0V (50th cycle). For nickel-metal hydride batteries, after repeating 400 cycles of 1-4, the 0.2C discharge time should be more significant than 3 hours; for nickel-cadmium batteries, repeating a total of 500 cycles of 1-4, the 0.2C discharge time should be more critical than 3 hours.

Refers to the internal air pressure of the battery, which is caused by the gas generated during the charging and discharging of the sealed battery and is mainly affected by battery materials, manufacturing processes, and battery structure. The main reason for this is that the gas generated by the decomposition of moisture and organic solution inside the battery accumulates. Generally, the internal pressure of the battery is maintained at an average level. In the case of overcharge or over-discharge, the internal pressure of the battery may increase: For example, overcharge, positive electrode: 4OH--4e → 2H2O + O2↑; ① The generated oxygen reacts with the hydrogen precipitated on the negative electrode to produce water 2H2 + O2 → 2H2O ② If the speed of reaction ② is lower than that of reaction ①, the oxygen generated will not be consumed in time, which will cause the internal pressure of the battery to rise.

IEC stipulates that the standard charge retention test for nickel-metal hydride batteries is: After putting the battery at 0.2C to 1.0V, charge it at 0.1C for 16 hours, store it at 20℃±5℃ and humidity of 65%±20%, keep it for 28 days, then discharge it to 1.0V at 0.2C, and Ni-MH batteries should be more than 3 hours. The national standard stipulates that the standard charge retention test for lithium batteries is: (IEC has no relevant standards) the battery is placed at 0.2C to 3.0/piece, and then charged to 4.2V at a constant current and voltage of 1C, with a cut-off wind of 10mA and a temperature of 20 After storing for 28 days at ℃±5℃, discharge it to 2.75V at 0.2C and calculate the discharge capacity. Compared with the battery's nominal capacity, it should be no less than 85% of the initial total.

The high temperature and humidity test of Ni-MH battery are: After the battery is fully charged, store it under constant temperature and humidity conditions for several days, and observe no leakage during storage. The high temperature and high humidity test of lithium battery is: (national standard) Charge the battery with 1C constant current and constant voltage to 4.2V, cut-off current of 10mA, and then put it in a continuous temperature and humidity box at (40±2)℃ and relative humidity of 90%-95% for 48h, then take out the battery in (20 Leave it at ±5)℃ for two h. Observe that the appearance of the battery should be standard. Then discharge to 2.75V at a constant current of 1C, and then perform 1C charging and 1C discharge cycles at (20±5)℃ until the discharge capacity Not less than 85% of the initial total, but the number of cycles is not more than three times.

At present, nickel-cadmium, nickel-metal hydride, and lithium-ion rechargeable batteries are widely used in various portable electrical equipment (such as notebook computers, cameras, and mobile phones). Each rechargeable battery has its unique chemical properties. The main difference between nickel-cadmium and nickel-metal hydride batteries is that the energy density of nickel-metal hydride batteries is relatively high. Compared with batteries of the same type, the capacity of Ni-MH batteries is twice that of Ni-Cd batteries. This means that the use of nickel-metal hydride batteries can significantly extend the working time of the equipment when no additional weight is added to the electrical equipment. Another advantage of nickel-metal hydride batteries is that they significantly reduce the "memory effect" problem in cadmium batteries to use nickel-metal hydride batteries more conveniently. Ni-MH batteries are more environmentally friendly than Ni-Cd batteries because there are no toxic heavy metal elements inside. Li-ion has also quickly become a common power source for portable devices. Li-ion can provide the same energy as Ni-MH batteries but can reduce weight by about 35%, suitable for electrical equipment such as cameras and laptops. It is crucial. Li-ion has no "memory effect," The advantages of no toxic substances are also essential factors that make it a common power source. It will significantly reduce the discharge efficiency of Ni-MH batteries at low temperatures. Generally, the charging efficiency will increase with the increase of temperature. However, when the temperature rises above 45°C, the performance of rechargeable battery materials at high temperatures will degrade, and it will significantly shorten the battery's cycle life.

01) Charging: When choosing a charger, it is best to use a charger with correct charging termination devices (such as anti-overcharge time devices, negative voltage difference (-V) cut-off charging, and anti-overheating induction devices) to avoid shortening the battery life due to overcharging. Generally speaking, slow charging can prolong the service life of the battery better than fast charging. 02) Discharge: a. The depth of discharge is the main factor affecting battery life. The higher the depth of release, the shorter the battery life. In other words, as long as the depth of discharge is reduced, it can significantly extend the battery's service life. Therefore, we should avoid over-discharging the battery to a very low voltage. b. When the battery is discharged at a high temperature, it will shorten its service life. c. If the designed electronic equipment cannot completely stop all current, if the equipment is left unused for a long time without taking out the battery, the residual current will sometimes cause the battery to be excessively consumed, causing the storm to over-discharge. d. When using batteries with different capacities, chemical structures, or different charge levels, as well as batteries of various old and new types, the batteries will discharge too much and even cause reverse polarity charging. 03) Storage: If the battery is stored at a high temperature for a long time, it will attenuate its electrode activity and shorten its service life.

Mura n-úsáidfidh sé an fearas leictreach ar feadh tréimhse fada, is fearr an ceallraí a bhaint agus é a chur in áit thirim íseal-teocht. Mura bhfuil, fiú má tá an fearas leictreach múchta, beidh an córas fós a dhéanamh ar an ceallraí go bhfuil aschur reatha íseal, a ghiorrú shaol seirbhíse na stoirme.

According to the IEC standard, it should store the battery at a temperature of 20℃±5℃ and humidity of (65±20)%. Generally speaking, the higher the storage temperature of the storm, the lower the remaining rate of capacity, and vice versa, the best place to store the battery when the refrigerator temperature is 0℃-10℃, especially for primary batteries. Even if the secondary battery loses its capacity after storage, it can be recovered as long as it is recharged and discharged several times. In theory, there is always energy loss when the battery is stored. The inherent electrochemical structure of the battery determines that the battery capacity is inevitably lost, mainly due to self-discharge. Usually, the self-discharge size is related to the solubility of the positive electrode material in the electrolyte and its instability (accessible to self-decompose) after being heated. The self-discharge of rechargeable batteries is much higher than that of primary batteries. If you want to store the battery for a long time, it is best to put it in a dry and low-temperature environment and keep the remaining battery power at about 40%. Of course, it is best to take out the battery once a month to ensure the excellent storage condition of the storm, but not to completely drain the battery and damage the battery.

A battery that is internationally prescribed as a standard for measuring potential (potential). It was invented by American electrical engineer E. Weston in 1892, so it is also called Weston battery. The positive electrode of the standard battery is the mercury sulfate electrode, the negative electrode is cadmium amalgam metal (containing 10% or 12.5% ​​cadmium), and the electrolyte is acidic, saturated cadmium sulfate aqueous solution, which is saturated cadmium sulfate and mercurous sulfate aqueous solution.

01) External short circuit or overcharge or reverse charge of the battery (forced over-discharge); 02) The battery is continuously overcharged by high-rate and high-current, which causes the battery core to expand, and the positive and negative electrodes are directly contacted and short-circuited; 03) The battery is short-circuited or slightly short-circuited. For example, improper placement of the positive and negative poles causes the pole piece to contact the short circuit, positive electrode contact, etc.

01) Whether a single battery has zero voltage; 02) The plug is short-circuited or disconnected, and the connection to the plug is not good; 03) Desoldering and virtual welding of lead wire and battery; 04) The internal connection of the battery is incorrect, and the connection sheet and the battery are leaked, soldered, and unsoldered, etc.; 05) The electronic components inside the battery are incorrectly connected and damaged.

To prevent the battery from being overcharged, it is necessary to control the charging endpoint. When the battery is complete, there will be some unique information that it can use to judge whether the charging has reached the endpoint. Generally, there are the following six methods to prevent the battery from being overcharged: 01) Peak voltage control: Determine the end of charging by detecting the peak voltage of the battery; 02) dT/DT control: Determine the end of charging by detecting the peak temperature change rate of the battery; 03) △T control: When the battery is fully charged, the difference between the temperature and the ambient temperature will reach the maximum; 04) -△V control: When the battery is fully charged and reaches a peak voltage, the voltage will drop by a particular value; 05) Timing control: control the endpoint of charging by setting a specific charging time, generally set the time required to charge 130% of the nominal capacity to handle;

01) Zero-voltage battery or zero-voltage battery in the battery pack; 02) The battery pack is disconnected, the internal electronic components and the protection circuit is abnormal; 03) The charging equipment is faulty, and there is no output current; 04) External factors cause the charging efficiency to be too low (such as extremely low or extremely high temperature).
