Explain the repair method and principle of 18650 lithium ion battery

18650 lithium-ion battery repair method: 1. Take out your battery after all is used up, and solve it with temperature. The battery can greatly reduce the use time under unstable temperature conditions, because the battery has no electricity and a very large part of lithium ion The positive ions already contain memory power. In that way, a part of the memory power can be released. Winter is here, put it outside for a while, and then go to the house. 2. There is also a way to remove the battery and leave it up and down for a week to gradually consume the electricity. You must first use the device to completely consume the electricity. Then charge it again. It is estimated that the charging time of your current battery is undoubtedly very short. After the charge is full, it is reasonable to disconnect it and charge it again for several times. The basic principle of lithium-ion battery repair method 1: long-term use of lithium-ion batteries will have a certain level of air oxidation on the metal surface, causing the battery on the mobile phone to not touch well with the mobile phone, and the use time of the lithium ion battery is shortened. Sassafras or other cleaning tools can wipe off the rusty chemicals on the surface, so that the battery and the phone will touch better. The basic principle of the second method of lithium-ion battery repair: to carry out deep charging and discharging on the mobile phone is to achieve a deeper level of re-battery charging based on the consumption of internal electromagnetic energy. This must choose some non-traditional methods. Think of a way to connect the mobile phone to a small 1.9V light bulb, and the power consumption inside the lithium-ion battery will be transferred to the light bulb until everything is exposed. The mobile phone must gradually consume light electromagnetic energy according to the lower operating voltage. Under all normal conditions, if the mobile phone is connected to the rated current of less than 3.6V, it will automatically turn on and off. When the battery is discharged, the battery on the mobile phone that is recharged can be used for a longer period of time. The basic principle of lithium-ion battery repair method three: ultra-low temperature can cause changes in the lithium-ion battery electrolyte inside the lithium-ion battery, and promote chemical changes in the battery that has just been refrigerated. The whole process of lithium-ion battery application is actually the whole process of battery charging. During this period, the positive and negative charges in the battery collide with each other. Batteries tend to become more and more useless, because the mechanical energy inside the electronic devices is relatively large at all normal indoor temperatures, so the battery is in an active state, and the power supply condition is relatively frequent. When the lithium-ion battery is placed in an ultra-low temperature natural environment, the external economic structure of the lithium-ion membrane on the surface of the lithium-ion battery and the lithium-ion battery electrolyte, and their boundary layers will all undergo significant changes, causing the battery to be temporarily inactive. Performance, the leakage current is reduced. Therefore, after recharging the battery, the standby time on the phone will increase.
