How to repair polymer lithium battery?

How to repair the polymer lithium battery▲The voltage of the lithium battery is lower than 2.7V, you can use the charger to charge the battery. After ten minutes, if the battery voltage rises, you can continue to charge until the charger prompts to be full, and then look at the full voltage. If the full battery voltage is 4.2V, it indicates that the battery is normal. If the full voltage is much lower than 4.2V, it means the battery is damaged. ▲If the battery is measured and the battery has no voltage, there are two situations at this time. One is that the battery is good, and it is caused by long-term storage. This kind of battery has a certain chance to recover. Generally, a lithium battery pulse activator is used to short the battery. Charge repeatedly over time. The repair cost is not low, it is better to replace it; another possibility is that the battery is completely worn out, the battery diaphragm is broken, and the positive and negative electrodes are short-circuited. At this time, you can only buy a new one. ▲The metal surface of the lithium battery used for a long time will be oxidized to a certain extent, resulting in poor contact. Use a rubber sassafras or other cleaning tools to erase the rusty material on the surface, and the lithium battery can recover a little. ▲Remove all the lithium batteries after they are used up and treat them with temperature. The battery will greatly shorten the use time when the temperature is unstable, because the battery has no electricity and a considerable part of the lithium ion already has a memory battery. The method can release a part of the memory battery. When winter comes, let it cool outside for a while, and then take it to the house.
