  • Q.

    What is the self-discharge of the secondary battery? What is the self-discharge rate of different types of batteries?

    A.

    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.

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%.

  • Q.

    What is the difference between the internal resistance of the charged state and the internal resistance of the discharged state?

    A.

    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.

    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.

  • Q.

    What is the difference between various standard rechargeable batteries?

    A.

    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.

  • Q.

    What are the main factors affecting battery life?

    A.

    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.

  • Q.

    What are the better conditions for battery storage? Do I need to charge the battery for long-term storage fully?

    A.

    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.
