Patent ID: 8614020

Claim:
An electrochemical device, comprising: a pair of electrode layers; and a solid electrolyte layer provided between the pair of electrode layers, wherein at least one layer of the electrode layers is composed of electrode active material particles each providing a function of the one layer, electrochemically inactive insulating particles and a binder which is composed of an organic polymer and binds the electrode active material particles and the electrochemically inactive insulating particles, wherein the solid electrolyte layer contains a silver-ion-conducting solid electrolyte, wherein the binder is carried on at least a part of a surface of each of the electrochemically inactive insulating particles, wherein each of the electrode layers is formed from a mixture material containing the electrode active material particles and the electrochemically inactive insulating particles with the binder, and wherein the electrochemically inactive insulating particles are at least one of an alumina, a silica and a zirconia.
