ELECTROCHEMICAL CELL WITH COMPACTED CATHODE CONTAINING POLYOLEFIN POWDER ADDITIVE

摘要

An electrochemical cell having a compacted e.g. extruded cathode wherein small amounts of a powdered polyolefin such as polypropylene are added to the active cathode material prior to compaction. The cathode mixture may comprise graphite, MnO2, polypropylene and KOH electrolyte and may be used with a zinc anode.
