Solution: 1. Cut off the battery case and connect the charger poles directly to the battery poles of the protection circuit (pay attention to the polarity and test the positive and negative poles with a multimeter first).
2. After a few minutes of charging, the battery voltage increases and the protection circuit may be opened.
You can then resume normal charging.
Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution.
The first lithium battery came from the great inventor Edison, using the following reaction: Li+MnO2=LiMnO2. This reaction is a redox reaction and a discharge.
As the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal have very high environmental requirements.
So lithium batteries have not been used for a long time.
Lithium batteries have now become commonplace.
