Abstract
There is provided a layer-built chemical cell device, which comprises: a positive electrode including a current collecting material and an active material layer; a negative electrode including another current collecting material and another active material layer; an electrolyte introduced in a sealed space formed by fixing together the positive electrode and negative electrode; a separator layer interposed between the positive electrode and the negative electrode. The active material layer of either the positive electrode or the negative electrode is formed by laminating a plurality of active material sub-layers containing one or more active materials, such an active material layer being depositted on a current collecting material so as to form either the positive electrode or the negative electrode.
