[0002] A battery is a cup, tank, or other container or composite container that contains an electrolyte solution and metal electrodes to generate an electric current. It is a device that converts chemical energy into electrical energy. Before filling a lithium battery with electrolyte, it needs to be cleaned to ensure that the injected liquid is not contaminated by impurities. At the same time, the electrolyte filling process needs to be carried out in a relatively vacuum environment to effectively prevent the entry of oxygen, moisture, or other impurities after the electrolyte is injected into the lithium battery, thereby ensuring the purity and stability of the lithium battery after electrolyte filling.
