Analysis of 18650 lithium battery maintenance methods

1. The metal surface of the lithium battery that is 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, and the use time of the lithium battery is shortened, and the rusty material on the surface can be wiped off with a rubber sassafras or other cleaning tools. , So that the battery is in contact with the phone better. 2. Remove the lithium battery, leave it for about a week, and slowly consume the electricity, first use the machine to completely consume the electricity. Then charge it all again. It is estimated that your current charging time must be very short. After the charge is full, disconnect and charge again, and repeat several times. 3. Let the lithium battery that is close to being scrapped completely discharge, and then recharge the battery to activate it. The detailed method is: deep discharge of the mobile phone is to achieve a deeper recharge by exhausting the internal electric energy, which requires some unconventional methods. 4. The low temperature can change the electrolyte inside the lithium battery, prompting the chemical reaction of the battery that has just been frozen. Putting a lithium battery into a low-temperature environment, the microstructure of the lithium film on the surface of the lithium battery and the electrolyte, as well as their interface, will change distinctly, resulting in temporary inactivity inside the battery and reduced leakage current. So after recharging, the standby time will be increased. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
