The facile synthesis and enhanced sodium-storage performance of a chemically bonded CuP2/C hybrid anode

A chemically bonded CuP2/C hybrid synthesized using a one-step mechanochemical reaction has been evaluated as an anode in sodium-ion batteries. Due to the synergistic effects of the formation of a strong P-O-C bond and the stable nanoscale conducting framework, it exhibits a high capacity with superior cyclability and rate performance.
