Abstract: A battery disclosed herein includes a container member housing an electrode body and a lead, a gasket, an external terminal, and a restraining member. The container member includes a terminal-connecting part having a thickness of 0.3 mm or less. The terminal-connecting part includes a through hole including a rising part. The gasket includes a hollow shaft inserted into the rising part. The external terminal includes a terminal shaft. The terminal shaft includes a diameter-reduction part. The restraining member restrains at least a part of the diameter-reduction part of the terminal shaft via the diameter-reduction part of the rising part and the shaft of the gasket. The inclination angle of the rising part is larger than the inclination angle of the terminal shaft.

Abstract: According to an embodiment, an electrode is provided. The electrode group includes a stack. The stack includes a positive electrode, a negative electrode or negative electrodes, and separator. Each negative electrode includes a negative electrode current collector and a negative electrode layer provided on the negative electrode current collector. The electrode group satisfies following relational formulae (I) to (III): 10≦a1/b1≦16 (I); 0.7≦D1/E1≦1.4 (II); E1≦85 (III). Here, the a1 [mm] is a thickness of the stack. The b1 [mm] is a thickness of the negative electrode current collector, or is a total thickness of the negative electrode current collectors. The D1 [μm] is a thickness of the positive electrode. The E1 [μm] is a thickness of the negative electrode.
