The CuCrO2-carbon nano-tubes (CNTs) nanocomposites synthesized by in-situ hydrothermal method exhibit excellent specific capacity retention and cyclic performances. Due to the poor conductivity and large volume variation of CuCrO2, its discharge capacity only remains 304 mAh g-1 (0.2 C) after 140 cycles. The electrochemical performances of CuCrO2 anodes are improved remarkably by adding 5-20 wt% CNTs. The CuCrO2-CNTS composite anodes maintain a specific capacity of 742 mAh g-1 after 60 cycles (0.2 C) when the CNTs proportion is over 10 wt%. Even at 1 C charge/discharge rates, they still exhibit high capacity retention of 530 mAh g-1 after 40 cycles. The SEM micrographs show that CNTs are dispersed well within the CuCrO2 matrix to form a 3D network. Such a network structure provides good electrical conductivity and restrains the volume variations during the cycling processes, which collaboratively improve the discharge specific capacity and cycling performance.
