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.
Connecting a higher-current power supply to a lithium-ion charger will damage the battery. Why? I am not asking how the battery gets damaged, because that answer is straightfoward. What I am asking is why lithium-ion chargers allow batteries to be damaged by excessive charge current in the first place.
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?
In this paper, the overcharge performance of a commercial pouch lithium-ion battery with Li y (NiCoMn) 1/3 O 2 -Li y Mn 2 O 4 composite cathode and graphite anode is evaluated under various test conditions, considering the effects of charging current, restraining plate and heat dissipation.
As a result, the voltage in the cell rises – this is known as over-charging. On the one hand, this is harmful to the battery and bad for its life span. On the other hand, it can pose a safety risk for the user. The excess energy leads to heat generation. “In the worst case, this can lead to a so-called ‘thermal runaway’.
What happens with metallic plating is that high charge currents force lithium ions to accumulate at the surface of the anode without being absorbed into the anode itself. The plated-out lithium can eventually form short circuits between internal battery components. And we sort of saw that with the laptop battery.

Charging Process: Lithium-batteries are charged with constant current until a voltage of 4.2 V is reached at the cells. Next, the voltage is kept constant, and charging continues for a certain time. The charger then switches off further charging either after a preset time or when a minimum current is reached. In the rare event that the charger does not switch off, for …
Increased Charging Time: Increased charging time suggests that the battery is not efficiently accepting charge anymore. This can happen as internal resistance grows, primarily due to aging and wear of battery components. Research by K. J.
