Lithium battery is a kind of secondary battery. Lithium battery is a kind of battery with lithium metal or lithium alloy as positive / negative electrode material and non-aqueous electrolyte solution. It has the characteristics of small volume, large capacity, light weight, no pollution, high energy density and low self discharge rate. It is recognized as a new energy battery product. Lithium batteries include lithium metal batteries and lithium-ion batteries, of which lithium-ion batteries can be recharged and are developed as the main power batteries.
Lithium batteries can be roughly divided into two categories
Lithium metal batteries and lithium ion batteries. Lithium ion batteries do not contain metallic lithium and can be recharged. Lithium metal battery, the fifth generation of rechargeable battery, was born in 1996. Its safety, specific capacity, self discharge rate and performance price ratio are better than lithium-ion battery. Due to its own high-tech requirements, only a few companies in several countries are producing this lithium metal battery.
