CoSe2 hollow boxes(HBs)/Ti3C2Tx composite is prepared by electrostatic self-assembly to take advantage of the high conductivity of Ti3C2Tx flakes and high theoretical capacity of CoSe2. The synergistic relationship between Ti3C2Tx and CoSe2 is studied by electrochemical impedance spectroscopy. CoSe2 HBs/Ti3C2Tx when used as the anode of sodium ion battery exhibits excellent rate performance and life cycle.
