Charging the lithium battery for the first time, need to charge more than 12 hours? -part 2
Therefore, all the pursuit of ultra-long charging for more than 12 hours and the use of lithium batteries for automatic shutdown are all wrong. If you have done it in the wrong way, please correct it in time, maybe it is not too late.
After the lithium battery is left for a period of time, it enters a sleep state. At this time, the capacity is lower than the normal value, and the use time is also shortened. However, the lithium battery is easy to activate, as long as the battery is activated after 3-5 normal charge and discharge cycles, the normal capacity is restored. Due to the characteristics of the lithium battery itself, it is determined that it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone does not require special methods and equipment during the activation process, and only needs to be fully charged, and not overcharged.
Expanding data
The migration rate of lithium ions in the electrolyte and the electrode sheets is closely related to the temperature, and too high or too low is harmful to the product. When the temperature drops below -20 degrees, the electrolyte in the battery will solidify, the internal resistance of the battery will become infinite, the battery will not be used; when the temperature rises above +55 degrees, the electrolyte will react side by side. A large amount of gas is generated, and the resin binder in the electrode sheet is also deteriorated, resulting in gradual aging and deterioration of the entire battery, and even failure in a short period of time. So to choose a reliable lipo battery charger is very essential.
The lithium battery will automatically discharge, and the self-discharge rate is about 2% per month. If it is not used for a long time, the battery will be damaged due to over-discharge. It is recommended to charge them once every few months to maintain 40% of the electricity. Just fine.
