Abstract
The problem of this invention is based on specifying a process for producing an industrial electrolyte that can be designed in the form of a thixotropic gel in the cells of lead storage batteries, with which large quantities of the liquids needed to fill the lead storage batteries can be prepared and mixed to improve its industrial usability. For the technical solution to this problem, the invention proposes that in the active masses of positive and negative plates in the storage battery cells, the quantity of sulfuric acid necessary to adjust the final acid density of the industrial electrolyte for the ready-to-use storage battery be stored in the form of lead sulfate, while, independently of this, water is set to a pH value from 4.1 to 4.7 by adding an acid and is then mixed with a gel former.
