<p>A prismatic battery has a 'jelly roll' type winding (2) positioned around a rigid spool (20) comprising tightly fitting horizontal plates (21, 22) connected by spaced-apart vertical struts (23, 24, 25). A prismatic battery has a 'jelly roll' type winding (2) positioned around a rigid spool (20) which comprises a horizontal upper plate (21) having the dimensions of the housing opening and a horizontal lower plate (22) having the internal dimensions of the housing base (15), the plates being joined by vertical central and side struts (23, 24, 25) which define two openings (26a, 26c) in the median plane of the spool (20) and a free space (27) at the periphery for fitting of the winding (2).</p> |
