LZ What you said about freezing is not just putting it straight in the fridge.
You have to freeze it before you can sprinkle it
1. Wrap the battery in newspapers before. put it in Wrap it in a plastic bag and put it in the freezer for three days (newspaper can absorb excess moisture
2. Take it out after three days and store it at room temperature for two days); ;
3. Charge the battery after two days. Once fully charged, place it in a phone to test (it is estimated that 80-90% can be saved).
This was revealed by an engineer from a well-known battery manufacturer. The principle is that there is battery fluid inside the battery. The reason the battery ages is because the battery fluid solidifies. The solution is to freeze the battery at low temperature, leaving all thebattery fluid to solidify, let it melt naturally, absorb excess water, then charge it fully so that all battery fluid is activated, good as new.
Can cell phone batteries be repaired if placed in the refrigerator?
Who taught you this? This method simply won't work.
After rechargeable batteries fail, some can be repaired, but their performance has deteriorated and some cannot be repaired.
To repair a rechargeable battery, you need to use a special instrument called a “battery repair instrument”; there is also a more advanced charger that can also be repaired. This charger not only has charging function, also comes with battery repair function.
1. This is unnecessary and will damage the battery;
2. The battery that was frozen for pfirst time cannot extend the battery life of the mobile phone. the “elixir of immortality” for cell phone batteries.
Low temperature can change the electrolyte inside the cell phone battery and promote chemical reactions in the newly frozen battery. The process of using a cell phone battery is actually a process of charging and discharging. During this time, the negative and positive charges of the battery collide. The reason why batteries become less and less durable is that at normal room temperature, the internal kinetic energy of electrons is relatively large, so the battery is in an active state and leakage is relatively frequent. When the battery is placed in a low temperature environment, the microstructure of the lithium film and the electrolyte on the surface of the lithium battery, as well as theur interface, will undergo significant changes, rendering the battery temporarily inactive and reducing leakage. current. Therefore, after recharging, the battery life of the mobile phone will increase.
3. At present, lithium batteries are generally used as mobile phone batteries. Theoretically, a lithium battery can be charged approximately 6,000 times. If the charging times are too long, the thermal movement of molecules will gradually destroy the microstructure of the internal molecular arrangement and the charge storage efficiency will gradually decrease.
4. The freezing process can easily destroy the original internal structure of the battery. It can increase the load capacity in a short time, but it may not be effective for long-term use. Once the microstructure of the battery is destroyed, it is impossible to completely recover it. The useLong-term use of this method will accelerate the loss of cell phone batteries.
