    摘要： A battery with improved safety that can more surely short-circuit electrodes when flattened out by the external force is provided. A center pin (30) is inserted in the center of a spirally wound electrode body formed by layering and spirally winding a cathode and an anode with a separator in between. The center pin (30) has a cut line (31) provided in the longitudinal direction and a first cutout (32) vertically crossing the cut line (31). When flattened out by the external force, a corner (33) at an intersection of the cut line (31) and the first cutout (32) is projected, and short-circuit is surely generated. Further, it is preferable that the center pin (30) has a second cutout (34) in the direction perpendicular to the cut line (31) in a position facing the cut line (31) in the circumferential direction. It is also preferable that the center pin (30) has a cross sectional shape of an oval or an ellipse, and the cut line (31) is provided in a position where the diameter of the oval or the ellipse is the largest.

    摘要： A battery capable of improving the energy density and cycle characteristics is provided. A cathode active material layer contains a complex oxide containing Li and Co as a cathode active material. An anode active material layer contains a CoSnC containing material containing Sn, Co, and C as an element, in which the content of C is from 16.8 wt % to 24.8 wt %, and the ratio of Co to the total of Sn and Co is from 30 wt % to 45 wt % as an anode active material. The surface density ratio of the cathode active material layer to the anode active material layer (surface density of the cathode active material layer/surface density of the anode active material layer) is from 2.77 to 3.90.

    摘要： A secondary battery capable of improving charge-discharge cycle characteristics in the case where an alloy material is used as an anode active material is provided. An exposed cathode region is disposed in an outer end portion of a cathode. The exposed cathode region includes an insulating protective member on at least one of an outer side and an inner side of the exposed cathode region in a position opposed to an outer end portion of an anode active material layer in one turn inside the outer end portion. In a cathode active material layer, a central angle between an outer end portion and a central end portion at the center of the spirally wound body is preferably within a range from 0° to −90° inclusive from the central end portion in a winding direction.
