Description

Technical Field

[0002] A battery refers to a cup, trough or other container or part of a composite container that contains an electrolyte solution and metal electrodes to generate electric current. It is a device that can convert chemical energy into electrical energy. When actually producing battery electrolyte, a batching device is required to complete the mixing of various raw materials for the battery electrolyte. In actual use, it has the advantages of simple operation, stable structure and precise batching.
