CuFe2S3 as electrode material for Li-ion batteries

Abstract : Electrochemical performances of the isocubanite CuFe2S3 tested as electrode material for Li-ion batteries have been investigated. A first discharge capacity of 860 mA h g(-1) shows a conversion process leading to Li2S, copper and iron nanoparticles. Interestingly, a reversible capacity of 560 mA h g(-1) at 1.5 V is demonstrated with good cyclability up to 30 cycles.
