One-Pot Synthesis and High Electrochemical Performance of CuS/Cu<sub>1.8</sub>S Nanocomposites as Anodes for Lithium-Ion Batteries
CuS and Cu<sub>1.8</sub>S have been investigated respectively as anodes of lithium-ion batteries because of their abundant resources, no environment pollution, good electrical conductivity, and a stable discharge voltage plateau. In this work, CuS/Cu<sub>1.8</sub>S nanocompos...

CuS and Cu<sub>1.8</sub>S have been investigated respectively as anodes of lithium-ion batteries because of their abundant resources, no environment pollution, good electrical conductivity, and a stable discharge voltage plateau. In this work, CuS/Cu<sub>1.8</sub>S nanocomposites were firstly prepared simultaneously by the one-pot synthesis method at a relatively higher reaction temperature 200 °C. The CuS/Cu<sub>1.8</sub>S nanocomposites anodes exhibited a high initial discharge capacity, an excellent reversible rate capability, and remarkable cycle stability at a high current density, which could be due to the nano-size of the CuS/Cu<sub>1.8</sub>S nanocomposites and the assistance of Cu<sub>1.8</sub>S. The high electrochemical performance of the CuS/Cu<sub>1.8</sub>S nanocomposites indicated that the Cu<sub>x</sub>S nanomaterials will be a potential lithium-ion battery anode. |
