Introduction to the charging and discharging principle and maintenance of lithium ion batteries

Sep.26, 2020

The working principle of lithium-ion battery refers to its charging and discharging principle. When the battery is charged, lithium ions are formed on the positive electrode of the battery, and the formed lithium ions move through the battery electrolyte to the negative electrode. The carbon as the negative electrode has a layered structure. It has many microporous plates. The lithium ions that reach the negative electrode are placed in the microporous plates of the carbon layer. The more lithium ions are placed, the higher the battery charging capacity.

 

It can be seen that during the charging and discharging process of lithium-ion batteries, lithium ions are in a state of movement from positive → negative → positive. If we compare the 18650 lithium-ion battery to a rocking chair, the two ends of the rocking chair are the poles of the battery, and the lithium ion is like an excellent track and field athlete running back and forth between the two ends of the rocking chair. Therefore, authoritative experts gave the 18650 lithium ion battery a lovely name, rocking chair battery. maintenance

01Original original equipment, protection circuit

 

Unmatched current and voltage during charging will cause damage to the circuit system, shorten the battery life, and even bring safety hazards. The original battery and charger are the best cp.

 

02 Moderate charge and discharge to prevent damage

 

Excessive charging and discharging will damage the battery to a great extent, so do not wait until the battery is completely exhausted before charging, and do not charge for too long (avoid charging overnight). Generally, keep it for 1-2 hours after the green light of the charger is on. .

 

03Pay attention to the charging environment and eliminate potential safety hazards

 

Charging in a humid rain and snow environment is easy to short-circuit the circuit; charging in the hot sun in summer can easily cause spontaneous combustion. In order to ensure safety, you should choose to charge in a dry, ventilated, and cool environment.
