Study of new electrode materials based on sulfides with a spinel structure

In this study, sulfide based spinel materials of tin and titanium were synthesized (Cu 2 FeTi 3 S 8 and Cu 2 FeSn 3 S 8 ). A topotactic substitution of tin by titanium atoms was performed in order to obtain electrode materials with high specific capacity associated to a good conductivity. According...

Description
Summary:In this study, sulfide based spinel materials of tin and titanium were synthesized (Cu 2 FeTi 3 S 8 and Cu 2 FeSn 3 S 8 ). A topotactic substitution of tin by titanium atoms was performed in order to obtain electrode materials with high specific capacity associated to a good conductivity. According to the first electrochemical tests the Cu 2 FeTi 3 S 8 spinel appears as a possible anodic material for the Rocking-Chair batteries.
