Abstract

ABSTRACT: Electrochemical performances of a prototype Lithium-Bromine battery (LBB) employing a solid electrolyte was investigated. It showed the discharge capacity of c.a. 147 mAh/(g-LiBr) for the first cycle, which decreased with repeating charge/discharge cycles. The capacity fading was mainly due to increase of the interfacial resistance between an aqueous active material solution and a solid electrolyte. From the results of symmetric cells and structural analysis of the surface of the solid electrolyte immersed in Br2 solutions, it was suggested that a Li + -depletion layer was formed on the surface of the solid electrolyte by contact with bromine.
