18650 lithium battery repair method
1. The metal surface of the lithium battery used for a long time will be oxidized to a certain extent, resulting in poor contact between the mobile phone battery and the mobile phone. The lithium battery is used for a shorter period of time, and the rusting substance on the surface can be erased by a rubber plaque or other cleaning tool. Let the battery and the phone become better.
2, remove the lithium battery, put a week or so, the electricity will be slowly consumed, you need to use the machine to completely consume the electricity. Then fully rush, it is estimated that your current charging time must be very short, after the full, disconnect and then rush, repeated several times.
3. Discharge the lithium battery that is nearly scrapped and recharge it to activate the battery. The specific method is: deep discharge of the mobile phone, by exhausting internal electrical energy, to achieve a deeper degree of recharging, which requires some unconventional methods.
4. The low temperature can change the electrolyte inside the lithium battery and promote the chemical reaction of the battery that has just been frozen. When the lithium battery is placed in a low temperature environment, the lithium film on the surface of the lithium battery and the microstructure of the electrolyte, and their interface will change significantly, resulting in a temporary inactivity of the battery and a decrease in leakage current. Therefore, after charging again, the waiting time will increase.
