ABSTRACT:
There is provided a layer-built chemical cell device, comprising a positive electrode including a current collecting material and an active substance, a negative electrode including another current collecting material and another active substance, an electrolyte and a separator both interposed between the positive electrode and the negative electrode. In such a layer-built cell device, the positive electrode and the negative electrode are in a belt-like shape, and are folded upon each other in a manner such that one electrode is always faced on both sides thereof with the other electrode, so as to form an electrode pair.
