With the development of science and technology, lithium batteries are widely used in many fields such as electric vehicles, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace, notebook computers, and mobile power supplies. The large-capacity lithium-ion battery currently developed has been used in electric vehicles and is expected to become one of the main power sources for electric vehicles in the 21st century, and will be used in artificial satellites, aerospace and energy storage.

With the shortage of energy in the world and the pressure of global environmental protection, lithium batteries are being widely used in the electric vehicle industry. Because the lithium ion battery needs to inject electrolyte into the battery during the production process, and then discharge the gas inside the battery through the formation process. This puts higher requirements on the sealing performance of the battery after liquid injection, the smooth exhaust during the formation process and the sealing performance after the completion of the formation.

There are many disadvantages in the operation process: seal failure is prone to occur, the operation process is cumbersome, and the cost is high. In order to be able to solve the problems in the existing technology, the lithium battery automated production line produced by the latest technology in Nichwell glove box  can ensure the liquid injection and exhaust, and also effectively prevent the external moisture from entering the battery and operate simple.
