Abstract
A separator system for a LiAl/FeS.sub.x electrochemical cell includes microporous sintered metal particle retainer screens fabricated by cold compacting, tape casting or plasma spraying, followed by sintering. The separator may consist of Al.sub.2 O.sub.3 or MgO powder, AlN microporous particles, AlN microporous disk or ceramic standoff sandwiched between two screens or Al.sub.2 O.sub.3 or MgO powder plasma sprayed onto one screen surface. The various separator system combinations are impregnated with 20% to 50% by volume electrolyte salt for ionic conductivity. Pore size is less than 10 .mu.m, excluding electrode particles from reaching the separator.
