2. Research on application technology of graphene Using graphene oxide or electrochemically exfoliated graphene as raw materials, the large-scale preparation technology of graphene fibers, membranes and three-dimensional macroscopic bodies was studied, and its potential applications were explored, which provided scientific and technical basis for the industrial application of graphene. 

3. Development of ionic liquid-based electrolyte Development of aqueous two-phase green synthesis and low-temperature recrystallization of ionic liquid technology, development of ionic liquid-based gel electrolyte and wide temperature range electrolyte, study its application in supercapacitors and micro energy storage devices. 

4. Supercapacitors and microelectrochemical devices The batch preparation process of high specific surface activated carbon with bimodal slit pore structure suitable for low temperature supercapacitors was carried out. Combined with ionic liquid-based electrolyte, an electric double layer supercapacitor with low temperature and high temperature resistance (> 85 oC) was developed. Research and development of electrochemical energy materials and devices for micro energy storage systems.
