Problems solved by technology

[0022] Therefore, since the electrolyte determines the charging capacity of electricity based on its concentration and amount and affects the reversibility of chemical reactions and the dynamics of the solution, there is a problem of lack of control over the process of setting the optimal concentration and preparing the electrolyte. State-of-the-art technology, and a large amount of sulfuric acid is used to stabilize the electrolyte
However, these attempts are only carried out in specific industrial fields such as the automobile industry, and have not been actively used in various fields.
