Abstract: A flat-shaped all-solid battery described in this application includes a battery container constituted by an outer can and a sealing can and a stack which a positive electrode, a solid electrolyte layer, and a negative electrode are stacked W form. The stack is housed in the battery container. A conducive porous member constituted by a molded body of graphite and having flexibility is disposed between the stack and an inner bottom surface of the outer can or an inner bottom surface of the sealing can. Moreover, in the above flat-shaped all-solid battery, the conductive porous member can be disposed between the stack and the inner bottom surface of the sealing can, and between the stack and the inner bottom surface of the outer can.

Abstract: The nonaqueous electrolyte battery has good storage characteristics in a high temperature environment. The inventive nonaqueous electrolyte battery includes: an electrode body that is obtained by laminating a positive electrode and a negative electrode with a separator in between; a nonaqueous electrolyte solution that contains a lithium salt and an organic solvent. The inventive nonaqueous electrolyte battery is characterized in that the positive electrode includes a lithium-containing layered nickel oxide that contains 50% by mole or more of Ni relative to Li; that the negative electrode includes a laminate that contains a metal base layer which is not alloyed with Li, and an Al active layer that is bonded to one surface or both surfaces of the metal base layer; and that a Li—Al alloy is formed on at least the surface side of the Al active layer.

Abstract: A non-aqueous electrolyte primary battery of the present invention includes: a negative electrode; a positive electrode; a separator; and a non-aqueous electrolyte. The negative electrode contains metallic lithium or a lithium alloy. The positive electrode contains a manganese oxide or a lithium-containing manganese oxide with a lithium content of 3.5% by mass or less. The non-aqueous electrolyte contains a phosphoric acid compound or a boric acid compound having in its molecule a group represented by General Formula (1) below, and the content of the phosphoric acid compound or the boric acid compound in the non-aqueous electrolyte is 8% by mass or less: where X is Si, Ge or Sn; R1, R2 and R3 independently represent an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 10 carbon atoms, or an aryl group having 6 to 10 carbon atoms; and some or all of hydrogen atoms may be substituted with a fluorine atom.

Abstract: Provided are a non-aqueous electrolyte battery that exhibits favorable load characteristics at low temperatures after being stored at a high temperature, and a method for manufacturing the non-aqueous electrolyte battery. A non-aqueous electrolyte battery of the present invention includes a negative electrode, a positive electrode, and a non-aqueous electrolyte.

Abstract: A polymer of the present invention has a plurality of pendant groups. Each of the pendant groups is constituted of a carboxyl group or a salt thereof, and a group interposed between a main chain and either the carboxyl group or salt thereof. The group interposed between the main chain and either the carboxyl group or salt thereof is: a hydrocarbon group; a perfluorocarbon group; constituted of a hydrocarbon group and at least one of an ester group and a carbonate group; or constituted of a perfluorocarbon group and at least one of an ester group and a carbonate group. A carbonyl carbon included in the carboxyl group or salt thereof is bonded directly to a carbon included in either the hydrocarbon group or the perfluorocarbon group.
