Description

technical field [0001] The invention belongs to the technical field of accumulators, and in particular relates to an electrolyte additive for lead-acid accumulators and a preparation method thereof. Background technique [0002] Most of the existing lead-acid series storage battery additives are liquid, and the main function of the additive is to prevent the lead plate of the storage battery from generating deposits and remove the lead sulfate deposits on the lead plate that has been corroded. After using liquid additives, although the original performance of the battery can be maintained, it has no effect on prolonging the life of the battery. Contents of the invention [0003] The invention provides a lead-acid storage battery electrolyte additive and a preparation method thereof, which solves the problems in the background technology above. The lead-acid storage battery electrolyte additive can improve the electrochemical performance of the battery, increase the cycle l...
