Abstract
Electrochemical reactions of LiVS2, Li2FeS4, and Li4FeS2 were investigated by using a Li+ ion conductive glass, 0.01Li(3)PO(4)-0.63Li(2)S-0.36SiS(2), as an electrolyte. The results showed remarkable differences from that in l iquid electrolyte; the redox couples of both Li2VS2/LiVS2 and LiVS2/VS2 wer e highly reversible, the reduction of Li2FeS2 led to the metastable phase L i4FeS2 that was completely reoxidized to the initial phase, and Li+ ions we re extracted from Li2FeCl4 without dissolution of the chloride itself. Thes e improvements by using the solid electrolyte make a large choice of electr ode materials. (C) 2001 Elsevier Science B.V. All rights reserved.
