Abstract
A battery electrode that can be bent in any shape without deterioration in battery performance. The metal current collector of the battery electrode has cut lines. This battery electrode is used for the positive or negative electrode of a non-aqueous electrolyte battery. The length of the cut lines is such that the ratio of y/x is from 0.2 to 0.9, with y being the total length of cut lines, and x being the distance between two points at which the extension of the cut line crosses both edges of the current collector.
