One-pot Solvothermal Synthesis of CuS-CNTs Hybrid as Binder-free Anode Material for Lithium Ion Batteries

CuS-carbon nanotubes hybrid (CuS-CNTs) was prepared by one-pot, facile microwave-assisted solvothermal method, and exhibited both good cycle stability and rate capability due to binder-free electrode and synergistic effect between CuS and carbon nanotubes. The reversible capacity of CuS-CNTs retained 477 mAh/g after 180 cycles at 0.2 A/g.204
