Recombinant electric storage battery
This patent describes a recombinant storage battery. It comprises: a plurality of positive plates containing about 2 to 4 percent of antimony based upon the total weight of the alloy and positive active material, and essentially antimony free negative plates in a closed case; a fibrous sheet plate separator between adjacent ones of the plates, and a body of an electrolyte to which the sheet separators are inert absorbed by each of the separators and maintained in contact with each of the adjacent ones of the plates. Each of the separator sheets comprising first fibers which impart to the sheet a given absorbency greater than 90 percent relative to the electrolyte and second fibers which impart to the sheet a different absorbency less than 80 percent relative to the electrolyte. The first and second fibers being present in such proportions that each of the sheet separators has an absorbency with respect to the electrolyte of from 75 to 95 percent and the second fibers being present in such proportions that the battery has a recombination rate adequate to compensate for gassing.
