Synthesis and Electrochemical Properties of CuC₂O₄·H₂O and CuC₂O₄·H₂O/Carbon Nanotubes (CNTs) Anodes for Lithium-Ion Batteries.

Pure CuC₂O₄·H₂O and CuC₂O₄·H₂O/carbon nanotubes (CNTs) composites are synthesized by a low-temperature hydrothermal process. The structure and morphology of the products are analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), thermogravimetric analysis (TG) and Raman spectrum. The results demonstrate that the as-prepared CuC₂O₄·H₂O takes on a microsphere-like morphology, all CuC₂O₄·H₂O/CNTs nanocomposites are constructed by the intertwining of tabular CuC₂O₄·H₂O nanoparticles (NPs) and CNTs to form a tanglesome net.
