Abstract: A battery is provided to ensure a short between electrodes when the battery is collapsed by external force, thereby inhibiting heat emission and improving the safety. A battery comprises: a bare cell having a cathode and an anode; a casing can(11) housing the bare cell, which is electrically connected to one of the cathode and the anode; and an external connection terminal connected to the other of the cathode and the anode, and having a plate-shaped base(151) received in the casing can and a portion(152) drawn to the exterior of the casing; and an insulation member for insulating between the external connection terminal and the bare cell, wherein the base of the external connection terminal is spaced apart from the inner wall surface of the casing can, and the insulation member has a notch at the portion where the insulation member overlaps with the base of the external connection terminal when viewed from the thickness direction of the casing can.

Abstract: A nonaqueous electrolyte secondary battery is disclosed, which comprises an anode having a carbonaceous material as the anode active material which permits lithium to be doped and undoped and a current collector, a cathode having a lithium compound as the cathode active material which permits lithium to be doped and undoped, and a nonaqueous electrolyte. The cathode active material contains the primary active material of a first lithium compound having the potential which is more "noble" than the potential of the current collector and the auxiliary active material of a second lithium compound having the potential which is more "base" than the potential of the current collector. The auxiliary active material works to avoid the dissolution of the anode current collector at the final stage of discharge.

Abstract: PROBLEM TO BE SOLVED: To establish a proper charge-discharge cyclic lifetime in a high energy density and high-temperature environment. SOLUTION: This nonaqueous electrolyte secondary battery uses a positive electrode material consisting of LixMO2 (M is at least one of Co, Ni, Mn and (x) is 1 or 0.5) and a negative electrode material consisting of a carbonaceous material. A positive 2 and a negative electrode 1 are band-shaped electrodes formed by molding the positive or negative electrode material on the two surfaces of a current collector, and a spiral electrode assembly is completed by winding round these electrodes 2 and 1 with separator 3 interposed. An organic solvent for electrolytic solution is a mixture solvent of propylene carbonate and diethyl carbonate.
