Dr. Haichao Chen, master's supervisor, specially-appointed professor of Qingdao University. Dr. Chen received his PH.D. in microelectronics and solid state electronics from Huazhong university of science and technology, and his current research interest focuses on energy storage devices including supercapacitors, lithium-ions battery, lithium-sulfur battery and sodium-ion battery. He first uses bimetallic sulfides and selenides as the electroactive materials for supercapacitors and harvest superior electrochemical performance than current electroactive materials. In addition, using the synergistic effect between graphene and PANI to improve the electrical conductivity of sulfur and suppress the dissolution and shuttle of polysulfide, superior electrochemical performance has been realized.  To date, more than 20 papers has been published on J. Mater. Chem. A、Nanoscale、J. Power Sources、Chem.–Asian J.、Electrochim. Acta, and so on. Wherein, six of the papers have now or once chosen as SCI 1% high cited papers with one of them is chosen as the SCI 0.1% hot paper, and the total citations of all the paper have been more than 700 times.
