Document Type and Number:
Japanese Patent JPH0754716
Kind Code:
B2
Abstract:
PURPOSE:To improve battery contents by composing an anode conductive material with the inner layer having the polar group contacting a solid electrolyte tube, and the outer layer unporvided a polar group. CONSTITUTION:An anode conductive material M, housed in the inside of an anode vessel 2 and composed of e.g., graphitic fiber (graphite system fiber) or a carbonaceous porous material of a carbon fiber or felt etc., has a two-layer structure of the inner layer M1 covering the surface of a solid electrolyte tube 5 and the outer layer M2 located at the outer side of the layer M1. The polar group of e.g. carbonyl group, carboxyl group, or halogen group etc. is given to the layer M1, and a polar group is unprovided to the layer M2. This enables battery contents increase since a sulfur generation reaction at the layer M1 part is constrained, and the smooth passing of a sodium ion made.
