A battery separator which exhibits good electrical conductivity and a high degree of inhibition to dendrite formation is formed of a substantially uniform mixture comprising (i) a thermoplastic rubber, (ii) an inert filler having a particle size of from 0.01 to 10 microns, (iii) a modifier for the thermoplastic rubber in a proportion of from 2 to 10 weight percent of the total weight of the mixture, and (iv) a processing agent selected from stearic acid, stearic acid metal salts, stearic acid amides and natural or synthetic waxes in a proportion of from 0.5 to 5 weight percent based on the total weight of the mixture. Since a sheet of the above composition can be made by calendering, using conventional equipment, a separator can be made very conveniently and cost-effectively. The separator is usable in acid and alkaline batteries. |
