One-Pot Synthesis and High Electrochemical Performance of CuS/Cu<sub>1.8</sub>S Nanocomposites as Anodes for Lithium-Ion Batteries

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...
