What is the principle and method of 18650 lithium battery repair

18650 lithium battery repair principle: repair principle 1. Long-term use of lithium battery metal surface will have a certain degree of oxidation, resulting in poor contact between mobile phone battery and mobile phone, lithium battery use time is short, and use rubber sassafras or other cleaning tools to clean the surface The rusty material keeps the battery in constant contact with the mobile phone. Act better. Repair principle 2. The deep discharge of the mobile phone is to achieve deeper recharging by depleting the internal electric energy, which requires some non-traditional methods. Find a way to connect the phone to a small 1.5 volt light bulb. The electricity inside the lithium battery will be transferred to the small bulb until all the lights are on. The mobile phone slowly drains its power through a lower voltage. Normally, if the connected voltage of the mobile phone is lower than 3.6 volts, the mobile phone will automatically shut down. Recharge, the battery can be used for a longer time. Repair principle 3. Low temperature can change the electrolyte of the lithium battery and promote the chemical reaction of the newly frozen battery. The use of lithium batteries is actually a charge and discharge process. During this period, the negative and positive charges in the battery collide with each other. The reason why batteries are becoming more and more impractical is that at normal room temperature, the internal energy of electrons is relatively large, so the battery is in an active state and leaks relatively frequently. When a lithium battery is placed in a low-temperature environment, the microstructure of the lithium film and electrolyte on the surface of the lithium battery and the interface between the lithium battery and the lithium battery change distinctly, making the battery inactive and reducing leakage current. So after charging, the standby time of the phone will increase. The cycle life of lithium batteries is about 600 times. If charged repeatedly, the thermal motion of the molecules will gradually destroy the internal arrangement and structure of the molecules, and the efficiency of storing charges will gradually decrease. The freezing process can easily damage the original internal structure of the battery, and the charging capacity may be improved in a short time, but long-term use may not be effective. Once the microstructure of the lithium battery is destroyed, it is impossible to fully recover. Long-term use of this method will accelerate the loss of mobile phone batteries. 18650 lithium battery repair method: 1. After the battery is fully used, remove the battery and use the temperature for production. When the temperature is unstable, the battery can greatly shorten the use time, because the battery has no electricity, and a large part of the lithium ion has memory , So you can release part of the memory power outside for a period of time in winter, and then return to the house. 2. Another way is to remove the battery and put it aside for about a week, so the power consumption will be slow. It has to be completely consumed by the machine first. Then make full use of it. It is estimated that your current charging time must be very short. When it is full, it will be cut off and repeated several times. It must be effective.
