What actually happens when lithium batteries are over-charged or deep discharged?
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

What special features are there to consider when designing-in a lithium polymer cell?
What special features are there to consider when designing-in a lithium polymer cell? An important point, according to battery expert Dr Jürgen Heydecke, is certainly the so-called “swelling”, the natural swelling of a lithium polymer cell in a fully charged state and over cycles. A fully charged cell is thicker than a discharged one. During

Passivation of Lithium Thionyl Chloride Batteries
Lithium thionyl chloride (LiSOCl2) batteries are special in many ways; with 3.6 volts, they have the highest cell voltage of any primary batteries available. They are also extremely durable and can be safely stored for long periods of time. This excellent shelf life is the result of another special feature of LiSOCl2 batteries called “passivation”.
