Abstract
The invention relates to a precursor for an electrical storage lead battery which can be converted into an operative storage battery by the mere addition of a sulphuric acid electrolyte. This precusor which has an unlimited shelf life consists of positive plates, of negative plate dispersed therebetween and of separator plates inserted between adjacent positive and negative plates and of a housing encasing the plates in dry condition. These separator plates consist of a densely compressed compact containing PA0 (a) 70 to 100% of pulverized silicon-dioxide or of another pulverized material which is capable of absorbing the liquid electrolyte and of being converted thereby into a pressure-resistant gel and PA0 (b) 0 to 30% of fibres of glass or any other acid-resistant and oxidation-resistant material.
