The correct usage of lithium ion battery and battery maintenance

Proper use of lithium-ion batteries Although lithium-ion batteries rarely have the memory effect of nickel-cadmium batteries, the memory effect is based on crystallization, which is almost absent in lithium-ion batteries. However, the capacity of lithium-ion batteries will still decrease after multiple charges, and the reasons are complex and diverse. The important reason is the changes in the anode and cathode materials themselves. From a molecular level, the positive and negative hole structures containing lithium ions will gradually collapse and block. From a chemical point of view, it is the active passivation of anode and cathode materials, and other stable compounds occur in side reactions. In some cases, the anode material gradually falls off, ultimately reducing the number of lithium ions that can move freely during the charge and discharge process. Overcharging and discharging cause permanent damage to the electrode of the lithium ion battery to the molecular level. It can be intuitively understood that the anode carbon emission will cause the excessive release of lithium ions and the collapse of the layer structure. Overcharging will harden too much lithium ions. It is inserted into the structure of the cathode carbon and some lithium ions can no longer be released. This is why lithium-ion batteries are usually equipped with charge and discharge control circuits. Improper temperature will trigger other chemical reactions inside the lithium-ion battery, and unwanted compounds will appear. Therefore, many lithium-ion batteries are equipped with protective temperature control films or electrolyte additives between the positive and negative electrodes. When the battery is heated to a certain extent, the composite membrane pores are closed or the electrolyte is denatured, the internal resistance of the battery increases until the circuit is disconnected and the battery no longer heats up to ensure the battery's normal charging temperature. Our opinion on battery maintenance is as follows: There is no need to deliberately ensure that every time the battery is discharged, it can be recharged. 2.3. The battery that has not been used for a long time should be placed in a cool place to reduce the passivation reaction speed. 4. The protection circuit also cannot monitor the self-discharge of the battery. If the battery is not used for a long time, a certain amount of electricity should be charged to prevent damage caused by excessive self-discharge during battery storage. In fact, there is not much attention to the use of the battery, in other words, not too much attention. How many times a battery can be used may depend more on the individual differences in the way the battery is made, rather than the way the battery is used.
