The lithium battery is made by the non - aqueous electrolyte and its negative pole’ material is the lithium metal or lithium alloy. The earliest lithium battery is made by the inventor Edison.
Since the lithium metal’s chemistry characteristic is very vigorous and its process, storage, usage need to be in a perfect environment. So the lithium battery have not been applied for a long time.

Lithium ion battery’s features:

1.With higher weight energy ratio and voltage energy ratio.
2. With high voltage and one battery’s voltage is 3.6V equal to 3 nimh or 3 nicd batteries’ voltage in series.
3.With low self-discharge to storage in long time. This is the battery’s most notably advantage.
4.With no memory effect and the battery do not need to discharge before charging.
5.With long life-span. In normal condition, the lithium battery’s circle life can be over 500 times.
6.It can be charged rapidly.
7.It can be used in parallel.
8.Because the battery is not including the cadmium, pb & mercury and it is eco-friendly in modern society.
9.With high cost and its price is higher than other batteries.
