LITHIUM BATTERY

摘要

PURPOSE:To improve the charge/discharge cycle life and discharge characteristic by adhering a conductive internal active material of electrode to the inner surface of a porous body. CONSTITUTION:A non-woven fabric of paper glass fiber 1 as a porous body 2 is adhered to a stainless foil 4 with a conductive adhesive 3. The resulting stainless foil 4 is put in an aqueous solution of V2O5.nH2O which is a positive electrode active material, and the porous body 2 is impregnated with the V2 O5.nH2O aqueous solution followed by drying to form the film of V2O5.nH2O 5 on the inner surface of the non-woven fabric which is the porous body 2. A one 6 obtained by impregnating a non-woven fabric consisting of polypropylene with an electrolyte obtained by dissolving lithium perchlorate in propylene carbonate is closely adhered to a positive electrode 7. A negative electrode 8 is then fitted thereto, and the stainless foil 4 circumference is sealed by a hot-melting sealing agent 9. Thus, a positive electrode having satisfactory charge/discharge cycle line and discharge characteristic can be manufactured without pressure molding.
