Reasons and repair methods of lithium battery capacity decline

The original source of the lithium-ion battery capacity is 1. the electrical core aging, the decline. 2.

Different discharge rate, resulting in unbalanced series core power, eventually leading to lithium ion battery capacity reduction is not durable. 3. In the battery and charge and discharge process, the vulcanization is affected by the battery capacity.

Battery vulcanization is manifested: the battery itself is low, and the charging will be full, and it will be no. Battery softening is: the internal liquid is turbid, black. The battery capacity is reduced, and the time is over and the lead powder falls off.

4. Improper charging in summer and winter. The battery charging voltage and ambient temperature are relative relationship, so the summer temperature is high, and the lithium-ion battery overcharges the battery to lose water, resulting in battery drums, deformed.

In winter, there is a mileage drop in winter. The restoration method of the lithium-ion battery capacity declines, it is more common to be two types: frozen method and overcharge. 1.

The frozen method will use the automatic shutdown old mobile phone lithium-ion battery to wrap the plastic film, and try to pay for the post when packaged, and ensure that the battery is in a vacuum state. Then, the three-layer newspaper is added outside the plastic wrap, so that the lithium ion battery is completely sealed. The refrigerator is placed in the refrigerator, after 48 hours, the battery is removed, and the lithium-ion battery does not cause surface expansion or deformation due to freezing.

After a while, then charge. 2, over-filled a way to completely discharge the lithium-ion battery close to the scrapped, then recharge the activation battery. The detailed way is to discharge the mobile phone, which is to reach a deeper and reproduction by depleting internal energy, which takes some unconventional approaches.

Connect with a specific device to a low voltage light bulb, the battery inside the battery will be transmitted to the small bulb until all are light. Mobile phone will slowly exhaust energy through lower voltage. Under normal circumstances, if the mobile phone is turned on less than 3.

6 volts rated voltage, it will automatically shut down. After the electricity is complete, the mobile phone battery that is recharged again can use longer.
