A rechargeable Mg2+/Li+ hybrid battery based on sheet-like MoSe2/C nanocomposites cathode

Sheet-like MoSe2/C nanocomposites were synthesized and employed as the cathode of a rechargeable Mg2+/Li+ hybrid battery for the first time, which exhibited an excellent electrochemical performance. The structure transformation of the MoSe2/C nanocomposite materials during the charge-discharge processes was identified by in situ XRD, and the electrochemical reactions taking place in the battery were evidenced.
