ABSTRACT:
The invention relates to electric cells which may comprise, for example, two trough-shaped elementary units mounted in a casing, each elementary unit comprising a relatively concavo-convex or trough-shaped positive electrode of compressed, plastified or sintered material, tightly sandwiched between two thin concavo-convex trough-shaped negative electrode parts obtained by folding a single electrode sheet around the positive electrode. Application of the invention is non-exclusively to alkaline storage cells.
