Introduction to how to repair lithium-ion batteries

How to repair 18650 lithium ion battery 1. Low temperature can change the electrolyte inside the lithium ion battery and promote the chemical reaction of the battery that has just been frozen. Putting a lithium-ion battery into a low-temperature environment, the microstructure of the lithium film and electrolyte on the surface of the lithium-ion battery, as well as their interface, will change significantly, resulting in temporary inactivity inside the battery and reduced leakage current. So after recharging, the standby time will be increased. 2. There is another way to remove the lithium-ion battery and leave it for about a week to slowly consume the electricity. You must 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 it and charge it again. Repeat a few times. It is absolutely effective. How to repair mobile phone lithium-ion battery 1. Use a clean eraser or cleaning tools of other materials to gently wipe the metal contacts on the lithium-ion battery and the metal contacts on the mobile phone, which will help the charging status and the lasting power. 2. Wrap the old cell phone lithium-ion battery that automatically shuts down with plastic wrap, and try to be as compliant as possible when wrapping it. There are three layers inside and outside to ensure that the battery is in a vacuum state. Then, wrap three layers of newspaper outside the plastic wrap to completely seal the lithium-ion battery. Put it in the freezer layer of the refrigerator. After 48 hours, take out the battery and remove the six layers of paper film wrapped one by one. The lithium-ion battery does not cause surface expansion or deformation due to freezing. After cooling for a period of time, then charge. 3. Let the lithium-ion battery that is close to being scrapped completely discharge, and then recharge and activate the battery. The specific method is: deep discharge of the mobile phone is to achieve a deeper recharge by depleting the internal electric energy, which requires some unconventional methods. How to repair the lithium-ion battery electric vehicle battery 1. The specification of the lithium-ion battery pack for electric vehicles is 48v20AH, which can be repaired with a 60V20AH battery charger; 2. The 48v12AH lithium-ion battery pack can be repaired with a 48v20AH battery charger. 3. Use the hot water from dry cleaners to repair lithium-ion batteries. The majority of electric vehicle users realize that electric vehicles are not far away and need to add distilled water to maintain and repair the batteries. However, the pure water and various supplementary liquids and repair liquids sold on the market have short-term uses for the battery, and then accelerate the deterioration of the battery's performance and discard it in advance.
