Title: SOLID CELL, CELL PACK, ELECTRIC VEHICLE, POWER STORAGE SYSTEM, ELECTRIC TOOL, AND ELECTRONIC DEVICE
Abstract:
A solid cell comprises: a positive electrode layer that stores and releases electrode reactant ions; a negative electrode layer that stores and releases electrode reactant ions and also partially faces opposite the positive electrode layer; and a solid electrolyte layer disposed between the positive electrode layer and the negative electrode layer, the solid electrolyte layer including a high-ion-conductivity part that is positioned in a region in which the positive electrode layer and the negative electrode layer face opposite each other and has relatively high ion conductivity, and a low-ion-conductivity part that is positioned in a region in which the positive electrode layer and the negative electrode layer do not face opposite each other so as to face opposite the positive electrode layer and has relatively low ion conductivity.
