摘要： PURPOSE:To retard the powdering and breaking of an electrode attendant on charge-discharge cycles and to lengthen the life of a negative electrode by using alpha-phase aluminium to which a third component which retards electrochemical reaction of aluminium with lihtium is added as a base material. CONSTITUTION:A base material is made of alpha-phase aluminium to which 0.1-20 wt% magnesium of alkali earth metal is added as a third component for retarding electrochemical reaction of aluminium with lithium. A degree that the third component retards the electrochemical reaction of aluminium is a level to lower the alloying start potential of alpha-phase aluminium with lithium by 0.05V or more than that of pure aluminium with lithium. As a result, a lithium-aluminium alloy layer is formed on the aluminium base material of a negative electrode 3, and the powdering and breaking of the electrode are retarded, and the life of the negative electrode is lengthened.

摘要： PURPOSE:To prevent the leakage of the electrolyte to elongate the life time of a secondary battery using an overcoating material made of a metal foil not making alloy with alkaline metals such as lithium coated with synthetic resin for at least the negative electrode. CONSTITUTION:An overcoating foil of a metal not making alloy with alkaline metals such as lithium e.g. stainless steel foil 1, instead of aluminum foil, is coated with an adhesive polypropylene layer 2 on the outside surface and an adhesive low density polyethylene base layer 3 on the inside surface and pressed and formed to a multilayer foil for the overcoating material A of the negative electrode. Thereby the leakage of the electrolyte of a sheet type secondary battery using an alkaline metal for the negative electrode can be prevented to elongate the life time.

摘要： PURPOSE:To obtain a battery capable of high current density discharge by using a polymer having conjugated double bond in its principal chain obtained by synthesizing it on conductive fibers by electrolytic polymerization as a polymer electrode. CONSTITUTION:An electrode having a thin polymer layer and large surface area is formed by electrolytically polymerizing polymer on conductive fibers. For example, polythiophene is obtained by electrolytical polymerization on carbon fibers by using a 0.5mm thick pitch family carbon fiber plate as an electrode, and acetonitrile solution containing 0.1mol/l of (C2H5)NBF4 and 0.1mol/l of thiophene as an electrolyte. This carbon fiber is washed with purified acetonitrile, and cut in a disk to form a positive electrode. A battery is assembled with this positive electrode, a lithium negative electrode, and an electrolyte made of propylene carbonate solution containing lithium perchlorate.

摘要： PURPOSE:To obtain a sheet-shaped battery having light weight and good charge- discharge performance by using a carbon fiber sheet as a current collector, and bonding gel or powder of synthetic polyacetylene to the carbon fiber sheet. CONSTITUTION:A battery case is formed with a sheet prepared by laminating polyethylene 1 on both sides of an aluminium foil 2. A carbon fiber sheet 7 serving as a current collector is heat-bonded on the inner side of the case. Polyacetylene powder containing toluene is placed on the carbon fiber sheet 7, and a liquid absorbent material is placed thereon, and they are pressed, then toluene is removed in a vacuum. An insulating sheet 6 and a separator 5 are placed between the carbon fiber sheets, and the peripheries of the battery cases are heat-bonded to form a bag, and electrolyte is poured into the bag, then the bag is sealed. By this constitution, a battery increases performance and its weight is also decreased.
