报告摘要:
The performance of electrochemical energy storagedevices relies largely on a scrupulous design of nanoarchitectures and smarthybridization of active materials. Nanoarray electrodes are particularlyinvestigated for power source in microelectronics, which requires high rates,high areal capacity/capacitance and long cycle stability. When the metal-ionbattery electrode materials are designed into nanostructures (e.g., 1D array,2D nanosheets), the pseudocapacitive effect may become dominating and can boostthe high-rate performance. Our group has been actively working on nanoarraymaterials directly on conductive substrates as electrodes of metal-ion battery.In this talk, I will articulate our material design strategies and how theextrinsic pseudocapacitance effect contributes to the high-rate performance ofa few types of 2D materials (VO2, SnS, MoSeS, NVOPF). This effectapplies to intercalation, conversion, as well as alloy type electrodes. Fullhybrid batteries (or called Li-ion or Na-ion capacitors) will also be presentedbased on such subtle designed electrodes.
