Energy and Optical Materials Laboratory involves energy materials, graphene and luminescence materials. For energy storage materials, we are interested in anode materials (Graphite, Hard carbon, Si, SiOx, TiNb2O7), cathode (NCM811, LiFePO4, Na0.7MnO2, Na0.7Mn1-xFexO2), solid electrolytes (Li7P3S11, Li10GeP2S12, Li6PS5Cl, Li3InCl6, Na3SbS4, Na3PS4) and so on. For graphene, we developed a green process to synthesize graphene with high quality. We also investigate graphene-based materials for battery, anticorrosion, heat dissipation, EMI shielding. For luminescence materials, we are interested in perovskite quantum dots, carbon dots, LED phosphors and so on.
