1,18650 Lithium-ion battery surface student repair method: long-term maintenance once the surface of the lithium ion battery will be oxidized to the extent, causing the battery electrode to be born, can make the battery and electrical equipment to be deteriorated Contact, the use time of the lithium-ion battery will be shortened, and once the rubber palm or any cleaning tool is used to wipe the rust-rust surface, the circuit resistance can be reduced and the conductivity can be lowered. 2. The 18650 lithium ion battery is regenerated by alternating cooling and heating: low temperature changes the electrolyte of the inner layer of the lithium ion battery and causes a new chemical reaction in the refrigerated battery.

Once the lithium ion battery is actually charged and emitted during the process of the lithium-ion battery. During this time, the negative charge and positive charge in the 18650 battery collide with each other. The battery becomes more useless is because the inner layer kinetic energy of electrons is relatively large at normal room temperature, so that the battery is in an active state to leak.

When a lithium ion battery is placed in a low temperature environment, the microstructure of the lithium-ion battery and the electrolyte surface and the lithium film on the interface thereof will have a significant change, which can cause the inner layer of the battery to be temporarily inactive and reduce the leakage current. Thus, after charging, the battery capacity can be recovered almost almost. The 18650 lithium-ion battery has a circulating life of approximately 600 times.

However, the number of non-charges has increased, and the thermal movement of the molecule will slowly destroy the microstructure of the inner molecular molecules, and the storage efficiency of the charge will slowly decrease. This is relatively easy to damage the default inside of the battery during freezing, this probability will increase the charging capacity in a short period of time, but once the probability is invalidated in the same time. When the microstructure of the 18650 lithium-ion battery is destroyed, it will be destroyed.

It is impossible to recover all, once the long-term, this method will accelerate the battery damage. 3, in-depth way to make an electronic battery: the in-depth power of the smartphone is to consume inner layer power to achieve deeper charging. This requires a lot of unopened methods.

Find a way to connect 18650 batteries to a small 1.5V bulb. The inner layer of the lithium-ion battery will be transferred to a small bulb, and it is until most of the bulbs are shining.

The battery must have slow power through a lower voltage. After the battery is applied, it can be used for longer at the same time. 4.

High-pressure charging method of the battery: once the lithium ion battery high pressure charger (5V, 300mA) is charged for 5 minutes. The charger can be a mobile phone charger or a charging head, but it is not possible to use the charger that may be used at the same time, the charger that may be usually used automatically. After each minute, the battery voltage V is detected again.

However, the no voltage rises to 1V, and it is fully charged (measured every 5 minutes). Charging to 3V, congratulations! Once you can use the charger that is usually used for the battery, you can automatically identify your battery.
