摘要： A laminated battery includes a stacked electrode group including a positive electrode, a negative electrode, a dummy electrode, a first separator interposed between the positive and negative electrodes, and a second separator interposed between the positive and/or negative electrode and the dummy electrode; and an electrolyte. At least one positive electrode and/or at least one negative electrode includes a single-sided electrode including a current collector and an electrode active material layer formed on a first surface of the current collector. A second surface of the current collector is exposed. The dummy electrode is a metal foil facing the second surface of the current collector of the single-sided electrode and having a polarity opposite to that of the single-sided electrode. Adhesive strengths F1 and F2 on both sides of the first separator and adhesive strengths F3 and F4 on both sides of the second separator satisfy F1+F2>F3+F4.

摘要： A flexible battery including a sheet-like electrode group including first electrode, second electrode, and an electrolyte layer; electrode lead terminals; and a housing. First ends of the electrode lead terminals are connected to the electrodes on a side S1t side of the electrode group. Each electrode includes a current collector and an active material layer. First active material layer (A1) on one main surface of first electrode has a non-facing portion (Pt) with respect to second active material layer (A2) on one main surface of second electrode on the S1t side, and a non-facing portion (Pn) with respect to second active material layer (A2) on one main surface of second electrode on the opposite side to the S1t. The shortest length LAt of the non-facing portion (Pt) and the shortest length LAn of non-facing portion (Pn) satisfy LAt

摘要： A thin battery includes a sheet-like electrode assembly; a non-aqueous electrolyte with which the electrode assembly is impregnated; and a housing in a sealed manner. The electrode assembly includes a pair of first electrodes located at an outermost side of the electrode assembly, a second electrode interposed between the pair of first electrodes, and a separator disposed between each first electrode and the second electrode. The first electrode includes a first current collector sheet and a first active material layer attached to one surface of the first current collector sheet. The second electrode includes a second current collector sheet and second active material layers attached to both surfaces of the second current collector sheet. A content x of the non-aqueous electrolyte per unit area of the first active material layer is larger than a content y of the non-aqueous electrolyte per unit area of the second active material layer.
