ENERGY STORAGE DEVICE AND METHOD OF PRODUCING SAME

摘要

Provided is an energy storage device that enables elements to be made thinner, and that can be manufactured cheaply and with few man-hours. The energy storage device comprises: a laminated body comprising a negative electrode layer positioned between at least two positive electrode layers, and separator layers disposed between the positive electrode layers and the negative electrode layer, or a laminated body comprising a positive electrode layer positioned between at least two negative electrode layers, and separator layers disposed between the negative electrode layers and the positive electrode layer; an electrolyte; and a package that holds the laminated body and the electrolyte. In the laminated body, adjacent positive electrode and negative electrode layers are directly bonded to the respective separator layers.
