[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and non-aqueous electrolyte solutions. In 1912, lithium metal batteries were first proposed and studied by Gilbert N. Lewis. In the 1970s, MS Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

[0003] The lithium battery casing is used to protect the internal lithium battery to prevent the lithium battery from being damaged. During production, the lithium battery casing needs to be welded, and the lithium battery casing needs to be positioned during welding, which is a relatively troublesome operation.

[0004] Therefore, a lithium battery housing having convenient welding positioning is provided. Utility Model Content
