Description

Technical Field

[0001] The present invention relates to the technical field of lithium batteries, and in particular to a novel lithium battery structure and an assembly process. Background Art

[0002] With the continuous growth of global energy demand and the urgent need for environmentally friendly energy, the popularity of electric vehicles, renewable energy storage systems and portable electronic devices has put forward higher requirements for high-performance, high-safety and long-life batteries. Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. 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 are rechargeable. The fifth generation of rechargeable batteries, lithium metal batteries, was born in 1996. Its safety, specific capacity, self-discharge rate and performance-price ratio are better than lithium-ion batteries. Due to its own high technical requirements, only companies in a few countries are now producing such lithium metal batteries.
