JPS55104079A - Solid electrolyte cell - Google Patents

Abstract

PURPOSE: To obtain a small sized and highly reliable cell by using as an electrolyte a AgI-Ag₂O-GeO₂ ternary composition made up in a fixed proportion in a solid electrolyte cell with Ag as cathode and I₂ as anode.

CONSTITUTION: A unit cell is made up by laminating the cathode(Ag) 3, the solid electrolyte (an AgI-Ag₂O-GeO₂ ternary composition) 4, and the anode (solid I₂) in order. The preferred molal proportion, or x, y, and z, of the AgI-Ag₂O-GeO₂ ternary composition as the solid electrolyte should be within the range surrounded by the points A, B, C, D, E, F, and G on the ternary composition ratio (x, y, and z) graph, as shown separately. For example, the molal ratios of the point A(x; 0.95, y; 0.025, z; 0.025), the point B(x; 0.9, y; 0.02, z; 0.08), the point C(x; 0.6, y; 0.08, z; 0.32), the point D(x; 0.63, y; 0.148, z; 0.222), the point E(x; 0.2, y; 0.4, z; 0.4), the point F(x; 0.4, y; 0.36, z; 0.24), and the point G(x; 0.86, y; 0.073, z; 0.067) are recommedable.
