Electrochemical Catalysis

更新时间:2018-09-11 00:57:43

      Electrochemical energy storage and conversion devices with high energy densities, like air-battery, fuel cell, and water splitting, are the promising technologies for the development of sustainable energy. For these devices, the electroactive cathode materials play a crucial role in the operation of the whole device. In our lab, via rational design material scheme, we enable to design and fabricate high active electrocatalysts like mullite oxides, layered-double hydroxide, carbon, and perovskite. Furthermore, we decorate the anode material to avoid the problems such as dendrite growth, passivation layer formation, etc. to ensure the safety, cyclicality, and high performance when the temperature is varying from -40oC to 80oC.

       We are also interested in the theoretical design of electrode material for supercapacitors(SCs) in the applications in portable electronics, electric vehicles, and smart grid. Through DFT-based calculations, we mainly focus on the low-dimensional materials like graphene, MXenes, etc.. We consider more realistic device operation conditions and tend to develop a new understanding of capacitance mechanisms and how to further improve and optimize the high-performance electrode materials.
