Repair method of 18650 lithium ion battery

18650 Lithium-ion battery repair principles and methods Lithium-ion battery repair method 2 Principle: Low temperature can change the electrolyte inside the lithium-ion battery and promote the chemical reaction that has just occurred in the battery. The use of lithium-ion batteries is actually a process of charging and discharging. During this period, the negative and positive charges in the battery collide with each other. Batteries are becoming more and more useless, because at normal room temperature, the kinetic energy inside the electronics is greater, so the battery is active and leaks relatively frequently. However, when the lithium-ion battery is placed in a low-temperature environment, the microstructure of the lithium film on the surface of the lithium-ion battery and the electrolyte and their interface surface will undergo significant changes, resulting in temporary deactivation of the battery and reduced leakage current. So after charging, the waiting time of the phone will increase. The cycle life of lithium-ion batteries is approximately 600 times. If there are too many charging times, the thermal movement of the molecules will gradually destroy the microstructure of the internal molecular arrangement, and the storage efficiency of the charge will gradually decrease. The freezing process can easily damage the original internal structure of the battery, which may improve the battery's ability to charge in a short period of time, but it may be invalid for long-term use. Once the internal microstructure of a lithium-ion battery is damaged, it cannot be completely restored. Long-term use of this method will accelerate the wear and tear of mobile phone batteries. The three principles of lithium-ion battery repair methods: deeply discharge the mobile phone, and achieve a deeper charge by exhausting the internal power supply, which requires the use of some unconventional methods. Find a way to connect the phone to a small 1.5 volt light bulb, and then the internal charge of the lithium-ion battery will be transferred to the light bulb until it is fully turned on. The mobile phone slowly runs out of power under low voltage. Under normal circumstances, when the mobile phone is connected, if the rated voltage is lower than 3.6 volts, the mobile phone will automatically shut down. After the battery is discharged, the mobile phone battery can be charged for a longer period of time. 18650 Lithium-ion battery repair method: 1. After using your battery, the temperature and battery temperature will be unstable, the use time will be greatly shortened, because the battery has no electricity and quite a lot of lithium-ion power can make memory in this way Electric release part of the winter, outside, and then to the house. 2. There is another way. Remove the battery and leave it for about a week. The power will be consumed slowly, and it will be completely consumed after using the machine. Then charge it. It is estimated that your current charging time must be very short. If it is full, disconnect and recharge. Repeat several times. It is absolutely effective. Battery repair refers to the use of physical or chemical means to repair secondary rechargeable batteries that have deteriorated or failed. Repair can restore battery capacity, extend battery life, and improve battery performance. Also known as a chemical power source, a battery is a device that can supply direct current to electrical appliances. Chemical power is an electrochemical reaction that converts chemical energy into electrical energy through oxidation and reduction. The primary battery is a disposable battery, and the secondary battery is a battery that can be used multiple times. Secondary batteries are also called rechargeable batteries or accumulators. Battery repair refers to the general term for battery repairs that are degraded or malfunctioned by physical or chemical means. Secondary batteries, also known as rechargeable batteries, refer to batteries that are activated by charging the active material and continue to be used after the battery is discharged. Important rechargeable batteries on the market include nickel metal hydride, nickel cadmium, lead acid (lead battery), lithium ion (including lithium ion batteries and lithium ion polymer batteries) and so on. There are many repair methods for lead-acid batteries, such as hydrotherapy, shallow-cycle high-current charging, nano-carbon sol battery activator repair, pulse battery repair instrument repair, and battery repair solution repair. Sulfate alkalization irreversible sulfate, referred to as sulfate alkalization. During the discharge of lead-acid batteries, the positive and negative plates combine lead sulfate. Lead sulfate is a hardly soluble and non-conductive substance. Under normal conditions, the formation of lead sulfate crystals in the battery after discharge is small. Under the application, it is relatively easy to dissolve and return to the lead. If used improperly, it often causes insufficient charging, water loss and over-discharge.
