Background

The lithium battery is a primary battery using lithium metal or lithium alloy as a negative electrode material and using a non-aqueous electrolyte solution, unlike a lithium ion battery, which is a rechargeable battery, and a lithium ion polymer battery. The inventor of lithium batteries was edison. 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. Therefore, lithium batteries have not been used for a long time. With the development of microelectronic technology at the end of the twentieth century, miniaturized devices are increasing, and high requirements are made on power supplies. The lithium battery has then entered a large-scale practical stage. However, in the actual production process of the lithium battery cap, because the protection treatment is improper, the lithium battery cap is easy to rust in the use process, and therefore, a protection treatment process for the lithium battery cap is provided.
