Nonaqueous electrolyte battery, cutter and method of manufacturing electrode

摘要

A nonaqueous electrolyte battery includes a case (20), an electrode group (7), positive electrode tabs (3) and negative electrode tabs (4). The electrode group (7) comprises a positive electrode (1), a negative electrode (2) and a separator (8). The positive electrode (1), the negative electrode (2) and the separator (8) are spirally coiled in a flat form. The positive electrode tabs (3) are electrically connected to at least two positions among tab positions P n of the positive electrode (1) and projected from one end surface of the electrode group (7). The negative electrode tabs (4) are electrically connected to at least two positions among tab positions N n of the negative electrode (2) and projected from the one end surface.
