METHOD FOR THE PREPARATION OF ELECTRODES FOR CHEMICAL ELECTRIC POWER SOURCES

摘要

The method can be used for the preparation of fibrous polymer material with metallized coating as a basis for electrodes for chemical electric power sources. It substitutes the palladium and tin by materials in less short supply which are used for carrying out the operations preceding the chemical metallization of polymer fibrous material. This is effected by the use of fibrous cation-exchange material with cation-exchange capacity from 0.5 to 6 mg.equ./g. Before the metallizsation the polymer material is saturated by nickel ions and is treated in aqueous solution of alkaline metal boron hydride.
