MANUFACTURE OF ORGANIC ELECTROLYTE BATTERY

摘要

PURPOSE:To easily improve a drop in voltage in the early discharge stage which is an intrinsic phenomenon of graphite fluoride-lithium battery by forming a porous aluminium layer on the surface of a positive mix molding by sputtering. CONSTITUTION:Mix powder comprising graphite fluoride, a conductive material, and a binder is molded with a mold to obtain a positive electrode 3. The posi tive electrode 3 is put in sputtering equipment and a porous aluminium layer 4 is formed on the partial or the whole surface of the positive electrode 3. The wetting capability of the positive electrode 3 to an electrolyte and the conductivity between a positive terminal and the active material of the positive electrode 3 are improved. The reaction area contributing to discharge reaction is enlarged and the discharge performance is increased. Therefore, a drop in voltage in the early discharge stage which is an intrinsic phenomenon of graph ite fluoride-lithium battery is improved.
