Abstract: A paste-like ink is prepared by dissolving camphor in an alcoholic solvent and dispersing fine carbon particles with a catalyst carried thereon in the solvent (step S100). A sheet-like electrode-forming member is formed on an electrolyte membrane by screen printing the paste-like ink thus obtained (step S102). The electrode-forming member is dried at 80° C. for one hour, in order to deposit camphor included in the electrode-forming member as a pore-forming agent (step S104). The electrode-forming member and the electrolyte membrane are joined with each other by hot pressing (step S106). The joint body of the electrode-forming member and the electrolyte membrane is dried under vacuum at 80° C. for three hours, in order to sublimate and remove camphor depositing in the electrode-forming member (step S108). This gives an electricity-generating layer that is a joint body of an electrode having a plurality of pores and the electrolyte membrane. The manufacturing process of the invention thus gives a joint body of an electrode having sufficient gas permeability and electrical conductivity and an electrolyte membrane.

Abstract: A conventional battery has a problem that when a temperature of the battery reaches at least 100° C. due to internal short-circuit or the like, large short-circuit current is generated, and therefore, a temperature of the battery further increases due to exothermic reaction to increase the short-circuit current. Also, if an aluminum laminated pack and the like are used as a casing material for the purpose of lightweight and improved energy density of the battery, and if an adhesive agent is used to joint an electrode with a separator to maintain the contact thereof, there is a problem that the adhesive agent intrudes into the opening part of the separator and the opening part area and the hole diameter decrease to bring about unfavorable results for discharge load characteristics of the battery. The present invention has been carried out in order to solve the above problems. The battery of the present invention comprises the active material layer 6 having the active material 8 and the electronically conductive material 9 contacted to the active material 8 and the electrolytic layer 3 jointed with the active material layer 6, wherein the electronically conductive material 9 contains an electrically conductive filler and a resin so that resistance can be increased with temperature rise, and wherein the active material layer 6 and the electrolytic layer 3 are laminated and jointed by thermal treatment.
