Abstract: A battery includes a power generating element containing a solid electrolyte, and a first member in contact with a principal surface of the power generating element. The principal includes a central portion and an end portion with a ring-like shape surrounding the central portion in a plan view. The first member includes a central region overlapping with the central portion of the principal surface in a plan view, and an end region overlapping with the end portion of the principal surface in a plan view. At least one of the central region or the end region is in contact with the principal surface. A Young's modulus of the end region is smaller than that of the central region.

Abstract: An apparatus for manufacturing an electrode includes a plurality of guide rollers configured to transport an electrode plate. The apparatus detects a defect on the electrode plate being transported and cut, upon detecting the defect, the electrode plate at a starting part of the defect on the electrode plate to form a defective electrode plate. The apparatus also includes a first taping part connecting the defective electrode plate to a defective electrode roll. The apparatus cuts the electrode plate at an ending part of the defect on the electrode plate to form a normal electrode plate. The apparatus connects the normal electrode plate separated from the defective electrode plate in the second cutting part with a normal electrode roll. The apparatus winds and transports the normal electrode roll.

Abstract: The invention relates to a method and a device for producing an electrode-separator assembly for a battery cell. The method comprises the following: supplying a separator material (2) by means of a separator supply device; supplying an electrode (9; 10) by means of an electrode supply device; and producing an electrode-separator assembly by means of a joining device, the electrode (9; 10) being joined to the separator material (2) and an adhesive bond being formed between the electrode (9; 10) and the separator material (2). The electrode (9; 10) and the separator material (2) are joined using at least one vacuum roller (5; 6) which is designed, by means of a roller suction device in a first surface region of a roller body of the vacuum roller (5: 6), to hold the electrode (9; 10) on the roller body at least for supply and, by means of a roller nozzle device in a second surface region of the roller body which is different from the first surface region, to push the electrode away from the vacuum roller (5: 6) towards the separator material (2) for joining, the separator material being supported for joining by a support device which is arranged opposite the vacuum roller (5; 6).

Abstract: A non-aqueous rechargeable battery includes an electrode body, a non-aqueous electrolyte solution, and a case. In the electrode body, a cathode sheet and an anode sheet are stacked with a separator arranged in between. The case accommodates the electrode body and the non-aqueous electrolyte solution. A cell compression parameter obtained by dividing a cell compression force, obtained by multiplying a difference of an internal pressure of the case relative to an atmospheric pressure by an area of a flat portion of the electrode body, by a spring constant of the case is in a range of 0.000 to 0.007.
