ABSTRACT: The performance of electrochemical energy storage devices relies largely on a scrupulous design of nanoarchitectures and smart hybridization of active materials. Nanoarray electrodes are particularly investigated for power source in microelectronics, which requires high rates, high areal capacity/capacitance and long cycle stability. When the metal-ion battery electrode materials are designed into nanostructures (e.g., 1D array, 2D nanosheets), the pseudocapacitive effect may become dominating and can boost the high-rate performance. Our group has been actively working on nanoarray materials directly on conductive substrates as electrodes of metal-ion battery. In this talk, I will articulate our material design strategies for both vanadium based intercalation-type cathode (VOx, NVOPF) and tin based alloy-type anodes (SnS2, SnS, SnSe2), as well as di-chalcogenide MoSe2. Most of these materials are made to 2D structure and employed for Na-ion and Zn-ion batteries. These examples demonstrate clearly the contribution of extrinsic pseudocapacitance effect to the high-rate performance. I will present array-based full Na-ion hybrid batteries and Zn-ion batteries.
