CAPA DE RESPALDO DE ELECTRODO Y METODO DE PREPARACION

摘要

This disclosure is directed to the preparation of cohesive, self-sustaining electrode backing layers by a method comprising mixing from 5 to 50 weight parts of polytetrafluoroethylene (PTFE) having a particle size ranging from 0.05 to 0.5 micron with from 95 to about 50 weight parts of carbon black of a particle size ranging from about 50 to 3000 angstroms and a density of about 1.95 grams per cubic centimeter, to produce an electrode backing layer having enhanced electrical conductivity compared to backing layers made from PTFE alone.
