Why is over-discharge protection important for lithium-ion batteries?
However, with the increasing demand for safe transport and green recycling of lithium-ion batteries, over-discharge protection and even zero-volt protection have a broad application in more working devices. Over-discharge causes severe Cu dissolution and SEI degradation, which is mainly attributed to the raised anode potential.

A lithium-ion battery (LIB) may experience overcharge or over-discharge when it is used in a battery pack because of capacity variation of different batteries in the pack and the difficulty of maintaining identical state of charge (SOC) of every single battery. A series of experiments were established to investigat
Can a lithium battery be overcharged?
In order to operate lithium-batteries safely and optimize their life span, they should not be over-charged or deep discharged. What happens when a battery is over-charged? If neither the charger nor the protection circuit stops the charging process, then more and more energy enters the cell.
