PURPOSE:To obtain a larger discharge current by employing a material mainly composed of NbxZrSy (0<x<1, 1.8<=y<=2.1) or a compound of NbS2 and ZrS2 as a positive electrode material. CONSTITUTION:A negative electrode mainly composed of metal copper, a Cu<+> ion conductive solid state electrolyte and a positive electrode mainly composed of sulfide of Nb and Zr are laminated sequentially, and the obtained cell can be recharged by irradiating the light onto the positive electrode. Main cause of polarization of cell is the activating energy for moving the charges on a contacting face between an electrolyte and a positive electrode material. The lower the activating energy, the quicker the electrons are passed and received, thereby the polarization as a cell becomes lower. When ZrS2 is doped with Nb, the activating energy will lower so as to reduce the polarization. |
