Abstract

Abstract: Transition metal selenides/oxides have received extensive attention, due to there suitable voltage plateaus and abundant reserves. However, intrinsic low electrons conductivity and huge volume change during sodiation/desodiation progress limit its wide application. To address these issues, CoSe2 @Fe3 O4 @Fe2 O3 with heterogeneous structure was successfully synthesized. As a SIBs anodes, the CoSe2 @Fe3 O4 @Fe2 O3 composite presents high electrochemical reversibility with a capacity of 360 mA h g −1 after 100 cycles at 100 mA g −1 .
