Problems solved by technology

The formation of lead-acid batteries is divided into internal formation and external formation processes. With the development of the industry, the internal formation method has gradually replaced the external formation method. No matter which method is used, there are three unavoidable problems in the formation. First, the formation A large amount of heat will be generated during the process, and cooling equipment or corresponding cooling conditions are required to cool down. The second is that rich liquid formation is used in the formation process. After the formation is completed, acid pumping treatment is required, which is a waste of labor. The extracted acid needs to be treated. , generate cost, pollute the environment, and thirdly, charge dozens of times of electricity in the formation, wasting energy

Description

technical field [0001] The invention relates to a charging and discharging formation process of a zinc-nickel battery. Background technique [0002] Lead-acid batteries are very popular in people's production and life. Lead-acid batteries have the characteristics of low price, convenient use and stable performance. They have been widely used in various fields. occupies a large share. The formation of lead-acid batteries is divided into internal formation and external formation processes. With the development of the industry, the internal formation method has gradually replaced the external formation method. No matter which method is used, there are three unavoidable problems in the formation. First, the formation A large amount of heat will be generated during the process, and cooling equipment or corresponding cooling conditions are required to cool down. The second is that rich liquid formation is used in the formation process. After the formation is completed, acid pumpi...
