Abstract
The present invention relates to an electrical storage cell (1) comprising a positive terminal (5), a negative terminal (4), a positive electrode (8) and a negative electrode (9) electrically connected to the positive terminal and to the negative terminal, respectively. Additionally, there is a collector of a first polarity (20) having a plane part (21) is electrically connected to the electrode of the first polarity, and bent electrical connection means (26) connecting the plane of the collector to the terminal of the first polarity and having a bending radius of curvature less than that of a part having the same thickness as the plane part. The invention also relates to the method of assembling this kind of electrical storage cell.
