Synthesis, characterization and electrochemical performance analysis of nanomaterials for high capacity lithium batteries
School of Automotive Engineering, Nantong Institute of Technology, Nantong, 226002 Jiangsu, China
The synthesis and electrochemical characteristics of nanomaterials for high-capacity lithium batteries are analyzed. α-CuV2O6 nanowires were obtained by the hydrothermal method. The mechanism of lithium intercalation and the electrochemical characteristics of α-CuV2O6 nanomaterials have been studied. The results show that α-CuV2O6 nanomaterials have the advantages of large surface area and short path of solid-state diffusion of lithium ions, which can greatly improve the electrochemical performance. At a current density of 20 mA/g, the specific discharge capacity of α-CuV2O6 nanomaterials can reach 514 mAh/g, and the apparent activation ability of the TV output reaction can reach 39.3 kJ/mol, which is much better than that of submicron wires and micron rods with particles of α-CuV2O6 nanomaterials. Therefore, α-CuV2O6 nanomaterials exhibit more efficient electrochemical performance in lithium primary batteries and have great development prospects.
