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.
In the case of lithium-batteries, this can lead to the cell opening and possibly burning down. “With lithium-polymer batteries, it should also be noted that gas formation can occur in the cell, which leads to the severe swelling of the cell.” The next step would also be thermal runaway and, thus, burnout.” And what about deep discharge?
So in here in this post, we share with you some of the most commonly seen root causes to lithium-ion battery accident and their solutions. Hope our post help you with what you need. If the voltage is below 2V, the internal structure of lithium battery will be damaged, and the battery life will be affected.
The most common cutoff voltage for a lithium ion battery is 4.2 volts per cell. To determine whether or not people have overcharging battery like lithium ion battery, we need to simply check whether the voltage of the battery pack exceeds the charging cut-off voltage.
In simple terms, voltage is the electrical pressure that pushes electrons through a circuit. For lithium-ion batteries, voltage is crucial because it directly relates to how much energy the battery can store and deliver. Think of voltage like water pressure in a hose. The higher the pressure, the more water (or in our case, energy) can flow.
Yes, it is dangerous to attempt to charge a deeply discharged Lithium battery. Most Lithium charger ICs measure each cell's voltage when charging begins and if the voltage is below a minimum of 2.5V to 3.0V it attempts a charge at a very low current . If the voltage does not rise then the charger IC stops charging and alerts an alarm.
Examining Failures in Lithium-ion Batteries
Overvoltage is when the charging voltage of the lithium-ion battery cell is increased beyond the predetermined upper limit, typically 4.2 V. The excessive current flow into the lithium-ion cell causes overheating and lithium plating, which leads to battery failure.

The damage caused by overcharging battery and how to prevent it
For lithium ion battery, the discharge cut-off voltage of a single cell is 2v, the charging cut-off voltage is 3.65v, and the full charge voltage is 14.6v. Therefore, the normal voltage should be between 8-14.6v. It is not normal if the voltage is higher or lower than this range, which may cause overcharging battery.
