1). Hydrogen Storage Materials
Hydrogen storage materials is a sort of materials can absorb or desorb hydrogen under certain conditions. Our lab focuses on the study of high-capacity lightweight hydrogen storage materials through theoretical calculations, nanostructures, multiphase composites, and other means to enhance the catalytic properties of magnesium-based hydrogen storage alloy hydride ligand and light metal hydrides, promote development of solid-state hydrogen storage technology and its application to promote the popularization of hydrogen.
2). Materials for Li-ion Batteries
Lithium-ion batteries are mainly to large and miniaturization two directions, but the battery capacity, energy density, power and other properties need to be further improved. The laboratory is committed to high-capacity, high-performance electrode materials research and development, mainly with a group phase multi-scale structure of Sn, Si, Al and other metal negative electrode and a positive electrode film Li-VO system, powder materials preparation and batteries performance evaluation.
3). Porous Metallic Materials
The porous metallic material is a kind of porous functional materials with high specific surface area, light weight, adjustable mechanical parameters and excellent energy absorption characteristics, has great value in the electrode material and catalyst supports and so on. Our lab committ to the preparation of a porous alloy of various pore structure, and to assess the phase transition behavior, mechanical properties and electrochemical properties.
4). Electrode Materials for Super Capacitor
Supercapacitors compared with rechargeable batteries (including NiMH batteries and lithium-ion battery), have a higher power density and longer cycle life. The electrode material is one of the key factors that determine the performance of electrochemical supercapacitors. Focusing on the development of nano structure, inexpensive transition metal oxide composite electrode material.
5).Advanced Materials Fabrication Methods
We focus on the developing various advanced fabricating methods for energy materials, such as mechanical alloying, PVD and chemical approaches etc. By using these methods, we had prepared various metastable and nanocrystalline materials, as well as hydrogen storage materials and lithium ion battery materials with designing multi-phase and multi-scale grains hydride structure.
6).Theoretic calculation of Materials
In our lab, we aim at understanding the mechanisms of hydrogen storage and dynamics for high-capacity hydrogen storage materials based on the quantum theory and molecule dynamics (MD) calculation, furthermore we try to explore the transportation micromechanism of energy storage particles in energy materials from atomic and molecular scale, and find out the key factors to influence the properties of energy materials.
