Investigation of the Properties of Anode Electrodes for Lithium–Ion Batteries Manufactured Using Cu, and Si-Coated Carbon Nanowall Materials

The fabrication of high-capacity, binder-free Li–ion battery anodes using a simple and efficient manufacturing process was reported in this research. anode material for lithium–ion batteries utilized is combination two-dimensional (2D) carbon nanowalls (CNWs) Cu nanoparticles (improved rate performance capacity retention) or Si (high capacity) nanoparticles. A methane (CH4) hydrogen (H2) gas mixture employed to synthesize CNWs on copper foil through microwave plasma-enhanced chemical vapor deposition (PECVD). were then deposited the CNW surface an RF magnetron sputtering equipment with four-inch targets. To analyze electrochemical LIBs, CR2032 coin-type cells fabricated materials based other components. It confirmed that Cu−CNW demonstrates improved performance, increased specific capacity, retention compared traditional anodes. Additionally, combined has enhanced LIB minimized volume changes during operation.
