COMPOUNDING AGENT COMPOSITION FOR CATHODE FILM, POLYETHER POLYMER COMPOSITION FOR CATHODE FILM

摘要

An compounding agent composition for a cathode film which comprises an activ e material and an electroconductivity imparting agent and exhibits an angle of repose of 35 degree or less; and a polyether polymer composition for a catho de film which comprises a polyether polymer and the above compounding agent composition for a cathode film. The extrusion of the polyether polymer composition allows the production of a cathode film having a low and uniform thickness and exhibiting stable electric characteristics, with high productivity.
