An insight into the sodium-ion and lithium-ion storage properties of CuS/graphitic carbon nitride nanocomposite.

ABSTRACT: Metal sulfides are gaining prominence as conversion anode materials for lithium/sodium ion batteries due to their higher specific capacities but suffers from low stability and reversibility issues. In this work, the electrochemical properties of CuS anode material has been successfully enhanced by its composite formation using graphitic carbon nitride (g-C₃N₄). The CuS nanoparticles are distributed evenly in the exfoliated g-C₃N₄ matrix rendering higher electronic conductivity and space for volume alterations during the repeated discharge/charge cycles. The 0.8CuS:0.2g-C₃N₄ composite when used as an anode for lithium ion coin cell exhibits a reversible capacity of 478.4 mA h g^-1 at a current rate of 2.0 A g^-1
