Description
Technical Field
The utility model belongs to the technical field of battery case, concretely relates to lithium cell shell.
Background
A "lithium battery" is a type of battery using a nonaqueous electrolyte solution with lithium metal or a lithium alloy as a negative electrode material. Lithium metal batteries were first proposed and studied by Gilbert n.lewis in 1912. In the 70 s of the 20 th century, m.s.whitetingham proposed and began to study lithium ion batteries. Because the chemical characteristics of lithium metal are very active, the requirements on the environment for processing, storing and using the lithium metal are very high. With the development of science and technology, lithium batteries have become the mainstream nowadays. The waterproofing of lithium batteries has become an important factor that has restricted their development.
