Long service life alkaline accumulator separators - comprise inorganic particles in a polymer binder, pref., styrene!-butadiene! or acrylic! acid-olefin! copolymer

摘要

A compsn. for producing alkaline accumulator separators comprises a polymer binder in which are embedded micrometric inorganic particles in amt. of 30-80 wt.% w.r.t. polymer and particles. The polymer is pref. a styrene butadiene or an acrylic acid-olefin copolymer. The particles are pref. TiO2, hydrated Ce oxide, Pb peroxide, Mg titanate, Ca zirconate, Al silicate and/or silica. Partic. suitable for Ni/Zn accumulators used in electrical vehicles. The separators can be easily produced and have relatively long service life even under conditions of high discharge, esp. when associated with other materials.
