What harm will lithium battery overcharge and overdischarge bring to the battery? Lithium battery is a rechargeable battery. The average lithium battery has a full charge of 4.2V. There are also batteries of other voltages. Lithium battery charging methods include fast charge, slow charge, trickle charge, constant current charge and so on. But pay attention to prevent lithium battery overcharge, overdischarge, short circuit protection and other problems.
1.Overcharging of lithium-ion batteries can easily cause the electrolyte in lithium-ion batteries to decompose and release gas, resulting in battery swelling, or even smoke and fire.
2. Overdischarge of lithium ion batteries will cause damage to the molecular structure of the cathode material of the battery, resulting in failure to charge the battery.
3. There is a battery management chip in the mobile phone or charger. When the battery charge and discharge reach the set value of the manufacturer, the charge or discharge will be terminated to prevent overcharge or overdischarge.
4. lithium ion battery should adhere to the principle of shallow charge and shallow discharge.
