    • A lithium ion secondary battery including: a positive electrode current collector; a positive electrode active material layer that is provided in contact with the positive electrode current collector; a separator layer that is provided on a side of the positive electrode active material layer on which the positive electrode current collector is not provided; a negative electrode active material layer that is provided on a side of the separator layer on which the positive electrode active material layer is not provided, that primarily contains silicon or tin, and that includes a opposing portion opposing the positive electrode active material layer and a non-opposing portion not opposing the positive electrode active material layer, the opposing portion and the non-opposing portion containing lithium produced by a thin film-forming method; and a negative electrode current collector that is provided on a side of the negative electrode active material layer on which the separator layer is not provided. Thereby, deformation of the negative electrode and deterioration in cycle characteristics accompanied by such deformation can be prevented.

    • Arnold (13) includes a recessed portion (21) for receiving a melt (2). The recessed portion (21) is constituted by an inner wall surface (29) for converting the melt (2) into a solidified portion when the inner wall surface (29) contacts the melt (2), and opens in a withdrawal direction (D1) of the solidified portion. A curved line formed by a first contour (23p) and a second contour (25p) has a cusp at a position of start points (43 and 45). The distance between the first contour (23p) and the second contour (25p) in a width direction (D2) increases continuously from an upstream side to a downstream side of the withdrawal direction (D1). The shape of the inner wall surface (29) of the recessed portion (21) is determined so that a cast rod (3) can be rotationally displaced clockwise or counterclockwise about an axis passing through a first end point (33) or a second end point (35) and perpendicular to a section of the mold 13.
    • Arnold(13)包括用于接收熔体(2)的凹部(21)。 凹部(21)由内壁面(29)构成,内壁面(29)在内壁面(29)与熔体(2)接触时将熔体(2)变形为固化部,并且在抽出方向(D1 )固化部分。 由第一轮廓(23p)和第二轮廓(25p)形成的曲线在起始点(43和45)的位置具有尖点。 第一轮廓(23p)和第二轮廓(25p)之间的宽度方向(D2)之间的距离从抽出方向(D1)的上游侧到下游侧连续地增加。 确定凹部(21)的内壁表面(29)的形状,使得铸造杆(3)能够绕通过第一端点(33)或第二端(33)的轴顺时针或逆时针旋转地移动 (35)并且垂直于模具13的一部分。
