What are the solutions after 18650 battery failure

1. Repair method for rust on the surface of 18650 lithium ion battery: once maintained for a long period of time, the metal surface of the lithium ion battery will be oxidized to a similar degree, causing the battery electrode to rust, which can make the battery and electrical equipment wires worse Contact, the use time of the lithium ion battery will be shortened, once the rusted surface is wiped with a rubber palm or any cleaning tool at the same time, the circuit resistance can be reduced and the conductivity can be improved. 2. Regenerate 18650 lithium-ion battery through alternate cooling and heating methods: low temperature will change the electrolyte in the inner layer of the lithium-ion battery and promote the chemical reaction of the new refrigerated battery. Once the lithium-ion battery is in the process of charging and generating electricity at the same time. During this period, the negative and positive charges in the 18650 battery collide with each other. The reason why the battery becomes more and more useless is because the inner kinetic energy of electrons is relatively large at normal room temperature, so the battery is in an active state and leaks relatively frequently. When a lithium-ion battery is placed in a low-temperature environment, the microstructure of the lithium-ion battery and the lithium-ion membrane on the electrolyte surface and its interface will change significantly, which can cause the inner layer of the battery to be temporarily inactive and reduce leakage current. Therefore, after charging, the battery capacity can be restored to a similar extent. The cycle life of the 18650 lithium ion battery is approximately 600 times. But without the increase in the number of charges, the thermal motion of the molecules will slowly destroy the microstructure of the inner molecular arrangement, and the storage efficiency of charges will slowly decrease. In the freezing process, it is easier to damage the default internal structure of the battery. This probability will increase the charging capacity in a short time, but the probability is invalid once the long-term nature is at the same time. When the microstructure of the 18650 lithium-ion battery is destroyed, it will be destroyed. It is impossible to recover all of them, and this method will accelerate the damage of the battery once the long-term at the same time. 3. The method of in-depth power generation to repair the battery: the in-depth power generation of the smart phone consumes the inner power source to achieve a deeper charge. There are many unconventional methods for this. Find a way to connect the 18650 battery to a small 1.5V bulb. The inner power of the lithium-ion battery will be transferred to the small bulb until most of the bulbs are on. The battery must slowly consume power through a lower voltage. After the battery is charged, it can be used for a longer time at the same time. 4. The high-voltage charging method of the battery: Once the lithium-ion battery high-voltage charger (5V, 300MA) is charged for 5 minutes at the same time. The charger can be a mobile phone charger or a charging head, but it cannot be a charger that is usually used at the same time, and the charger that is usually used may have an automatic recognition voltage. After every minute, the battery voltage V is checked again. But if the voltage does not rise to 1V, it will always charge (measure the voltage every 5 minutes). Charge to 3V, congratulations! You can charge the battery with the charger you usually use at the same time, and the charger you usually use at this time will automatically recognize your battery.
