PURPOSE:To obtain a very high energy density per unit mass of the positive electrode of a cell, and a high discharge voltage, and to keep it at a high constant value for a long time, by making the positive electrode with a composite of carbonaceous materials adhere and deposit onto a porous electro-conductive carrier. CONSTITUTION:In an organic electrolyte cell consisting of a negative electrode composed of active material of light metals a separator impregnated with organic solvent solution of light metal salts and a positive electrode, the positive electrode is made with a composite of carbonaceous materials adhered and deposited on a porous electro- conductive carrier. There is no special restriction as to the carbonaceous materials to be used, and they are not necessarily pure, and so a carbonaceous material of which carbon content is higher than 90wt% and electro-conductivity is less than 10<6>OMEGAcm is practically used. By making the positive electrode with a composite of carbonaceous materials adhered and deposited on a porous electro-conductive carrier, a very high energy density per unit weight of the positive electrode and a high discharge voltage can be obtained, the high discharge voltage can be kept constant for a long time, and there is no problem concerning public nuisance and recovery of resource, and furthermore it is inexpensive. |
