AN IMPROVED PROCESS FOR THE FABRICATION OF POROUS BICARBON-AIR ELECTRODE FOR METAL-AIR CELLS AND POROUS BICARBON AIR ELECTRODES THUS OBTAINED

摘要

An improved process for the fabrication or porous bi-carbon air electrode for metal-air cells for high current output comprising die molding of a tin plated expanded mild steel grid in the form of a packet, cooling the same with a uniform layer of acetylene black and a plastic binder mix, further coating the same with layer of activated carbon, electrolytic manganese dioxide, acetylene black and a plastic binder, heating the die and pressing at a pressure of 300 to 350 kilograms/Centimeter Square at a temperature of 130 degree - 140 degree Celsius, cooling the die to obtain metal reinforced carbon plates for use to form the electrode.
