Abstract

1511305 Reinforced felt battery separators SAFT - SOC DES ACCUMULATEURS FIXES ET DE TRACTION 19 May 1975 [24 May 1974] 21327/75 Heading D1R [Also in Division H1] A separator for an electric cell is made of an inorganic fibre felt or a synthetic polymer fibre felt and is reinforced by a regular network of fibres. The strengthening of the separators 1, 2 by the network enables the separators to be gripped between mandrels 5, 6 around which the electrodes 3, 4 are wound. For a lead - acid cell the fibres are made of glass or polypropylene whilst for an alkaline cell, polyamide or polyvinyl chloride fibres are used.
