Abstract

The invention discloses a preparation method of a storage battery electrolyte, and relates to the technical field of storage batteries. The preparation method comprises the following steps of dispersing fumed silica in deionized water to prepare a fumed silica hydrosol, adding surface-treated nano zeolite powder into the fumed silica hydrosol, stirring to obtain a nano disperse colloid, sequentially and slowly adding a sulfuric acid solution and sodium sulfate into the nano disperse colloid, sequentially adding stannous chloride, potassium sulfate and potassium succinate after slow stirring, and obtaining storage battery electrolyte through sufficient and uniform stirring. Through the matching of the components, the corrosion on the grid by the conventional electrolyte can be delayed, theself-discharge rate of the storage battery is reduced, and the evaporation condition of the electrolyte of the storage battery can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of storage batteries, and in particular relates to a method for preparing battery electrolyte.
