Additives for the extrusion of polymeric electrolytes.

摘要

Process for preparing an electrolyte film for lithium/polymeric electrolyte batteries, by extrusion for a polymer and a Li salt suitable for use in such electrolytes in the presence of ultrafine metal oxide powders with a particle size of 7-40 nm, which inhibit the formation of solid clumps in the powder mixt. to be extruded and thus facilitates the introduction of the mixt. into the extruder.
