The damage of lithium-ion batteries is often caused by various improper behaviors, which mainly include the following aspects:
1,Improper charging and discharging: Frequent high-speed charging and discharging can accelerate the damage of battery internal materials and the generation of polarization discharge, leading to battery performance degradation or even complete failure.
2,Overcharging and over-discharging: Overcharging can generate overvoltage inside the battery, causing it to heat up, produce bubbles, and even explode. On the other hand, over-discharging reduces the battery's power to a dangerous level, causing irreversible damage.
3,Excessive temperature: In high-temperature environments, the electrochemical reactions inside lithium-ion batteries accelerate, thereby shortening battery life and even causing battery leakage, expansion, or explosion.
4,Mechanical damage: Strong compression, impact, or drops can lead to battery case cracks, triggering leakage, internal short circuits, or uncontrolled chemical reactions.
5,Prolonged inactivity: Long-term non-use of lithium batteries can cause internal lithium ions to polarize and form crystals, resulting in decreased battery performance or even failure.
6,Using inappropriate chargers or cables: Unsuitable chargers may cause excessive or insufficient charging currents, affecting the normal electrochemical reactions inside the battery and damaging it.
7,Improper storage conditions: Storing lithium batteries near moisture, high temperatures, or corrosive substances can also cause damage to the battery.
Therefore, to extend the service life of lithium-ion batteries, users should avoid these improper behaviors and follow correct usage, charging, and storage practices.
