Abstract
Hybrid CuO/SnO2 nanocomposites are synthesized by a facile thermal annealing method on Cu foils. Compared to pristine CuO and SnO2 nanostructures, hybrid CuO/SnO2 nanocomposites exhibit the enhanced electrochemical performances as the anode material of lithium ion batteries (LIBs) with high specific capacity and excellent rate capability. The binder free CuO/SnO2 nanocomposites deliver a specific capacity of 718 mA h g-1 at a current density of 500 mA g-1 even after 200 cycles. The enhanced electrochemical performances are attributed to the synergistic effect between SnO2 nanoparticles and CuO nanoarchitectures. Such hybrid CuO/SnO2 nanocomposites could open up a new route for the development of next-generation high-performance and cost-effective binder free anode material of LIBs for mass production.
