What are the solutions for 18650 battery failure

    1. The repair method for nominal rust on 18650 lithium batteries: Long term persistence. Once the metal of the lithium battery is oxidized to almost the same level, it may cause rust on the battery, which may lead to poor contact between the battery and electrical equipment wires. The utilization time of the lithium battery will be shortened. Once the rust is wiped off with a rubber palm or cleaning tool at the same time, the circuit resistance may decrease and conductivity may be improved.

    2. Regeneration of 18650 lithium batteries through alternating cooling and heating methods: Low temperature will transform the electrolyte in the inner layer of the lithium battery and enhance the chemical reaction of the newly frozen battery. Once the process of lithium battery charging and discharging occurs simultaneously. During this period, the negative and positive charges in 18650 batteries collide with each other. The reason why batteries are becoming increasingly useless is that at deformed room temperatures, the inner kinetic energy of electrons is high, causing the battery to be in an active state and frequently leaking. When lithium batteries are placed in a low-temperature environment, significant changes will occur in the microstructure of the battery, as well as in the nominal electrolyte and the lithium film at its interface, which may result in temporary inactivity of the inner layer of the battery and a decrease in leakage current. So, after charging, the battery capacity may recover to a near level. The cycle life of 18650 lithium batteries is about 600 times longer. But as the number of uncharged molecules increases, the thermal activity of the molecules will slowly disrupt the microstructure of the inner layer molecular arrangement, and the storage efficiency of charges will slowly decrease; During the freezing process, it is relatively easy to damage the default internal structure of the battery, which may increase the charging capacity in a short period of time, but the probability is invalid for long-term use. When the microstructure of 18650 lithium batteries is disrupted, it will be destroyed. It is impossible to fully recover, as this method will accelerate battery damage in the long term.

    3. The method of repairing batteries with deep power generation: The deep power generation of smartphones consumes the inner power source to achieve deeper charging. There are many unconventional ways to do this. Find a way to connect an 18650 battery to a small 1.5V light bulb. The inner power supply of the lithium battery will be transferred to the small light bulb until most of the light bulbs are lit up. The battery should have a slow power consumption through lower voltage. After the battery is charged, it may take longer to use at the same time.

    4. High voltage charging method for batteries: Once the lithium battery is charged simultaneously with a high-voltage charger (5V, 300MA) for 5 minutes. A charger could be a mobile phone charger or charging head, but it is not possible to simultaneously use a commonly used charger. The commonly used charger may need to have active voltage recognition. Every minute, test the battery voltage V again. But if the voltage does not rise to 1V, continue charging (measure the voltage every 5 minutes). Charge to 3V, congratulations! Once you use the charger you usually use to charge the battery at the same time, the charger you usually use will actively recognize your battery.
