Nanocomposite Electrode Materials for High Energy Lithium Batteries
For the next-generation power requirements of 3C integration products and EV applications, the high-energy density and safe lithium-ion batteries should be developed in the future. This presentation will focus on the research results of high-capacity Li-rich composite cathode material and Si/C composite anode material. The rate capability of Li-rich composite cathode materials can be improved by the nanocomposite powder design. The irreversible capacity loss of composite cathode is reduced by the oxide nanocoating layer. The composite cathode materials have shown high reversible capacity (270 mAh/g) and high discharge rate (>5C). For the high-capacity Si/C composite anode materials, the morphologies of Si/C composite anode materials have shown the spherical-type particles and the core-shelled structure have reinforced the material structural integrity and prevent the volume expansion of nano Si. The irreversible capacity loss of Si/C composite anode materials have been reduced by carbon coating. The Si/C composite anode materials have shown high reversible capacity (650 mAh/g), low irreversible capacity loss (15%) and long cycle life (>200 cycles).
