Lithium batteries are primary batteries that have lithium as an anode,mainly including lithium-metal batteries,lithium-ion batteries and li-polymer batteries.however,the lithium-ion batteries and li-polymer batteries which have widespread application in every field of life has solved many problems for human beings ,firstly,as commonly used lithium battery ,li-ion battery has some advantage as :
1.The energy ratio is higher. With high storage energy density, it has reached 460-600wh /kg, about 6-7 times that of lead-acid batteries.
2.The working life is longer, it can reach more than 6 years, and the battery with lithium ferrous phosphate as the positive electrode and charged with 1C DOD has a record of using it 10,000 times.
Secondly ,the advantage for li-polymer batteries as :
1.No battery leakage problem, the battery does not contain liquid electrolyte since it uses colloidal solid
2.The battery can be designed in many shapes
3.It will have twice the capacity of a lithium-ion battery of the same size
