    摘要: A battery that can secure the sufficient capacity, reduces deviation of the pressure distribution inside a spirally wound electrode body, and shows the superior charge and discharge characteristics is provided. The battery includes: a spirally wound electrode body in which a cathode having a cathode active material layer on a strip-shaped cathode current collector and an anode having an anode active material layer on a strip-shaped anode current collector are layered with a separator in between, and spirally wound in a planular state; and a lead jointed to the cathode current collector or the anode current collector in a center portion of the spirally wound electrode body. An inner circumferential end of the cathode active material layer is provided in a region where the inner circumferential end does not overlap with the lead in a short axis direction of the spirally wound electrode body.

    摘要: A battery capable of improving high temperature characteristics is provided. An electrolytic solution is impregnated in a separator. The electrolytic solution contains an imide salt expressed by LiN(CnF2n+1SO2)(CmF2m+1SO2) (n and m are respectively an integer number from 1 to 4, and a different value from each other). Thereby, a coat stable even at high temperatures can be formed on the surface of a cathode or an anode, and chemical stability of the electrolytic solution at high temperatures can be improved. LiPF6 is preferably mixed in the electrolytic solution.
