PROCESS FOR THE PREPARATION OF CARBON FELT ELECTRODES FOR REDOX FLOW BATTERIES AND PROCESS FOR PRODUCING REDOX FLOW BATTERIES

摘要

A process prepares metal-doped felt fabric made from carbon fibers. A textile structure of pre-oxidized polyacrylonitrile fibers is carbonized at temperatures of up to 1500° C. and wherein polyacrylonitrile and/or oxidized polyacrylonitrile as precursor fibers are functionalized with a metal precursor.
