Peking University, Nov. 30, 2018: Professor Pan Feng from PKU’s School of Advanced Materials of Shenzhen Graduate School won the 2018 Battery Division Technology Award of the Electrochemical Society (ECS). In the 234th Americas International Meeting on Electrochemistry and Solid State Science (AiMES) (Cancun, Mexico), Pan Feng presented an award-winning report entitled “Research on Crystal Structure and Interface Structure and Performance of Lithium Battery Materials”. The meeting was jointly held by the ECS, the XXXIII Congreso de la Sociedad Mexicana de Electroquimica (SMEQ), the Sociedade Brasileira de Eletroquímica e Eletroanalítica (SBEE), the Sociedad Iberoamericana de Electroquímica (SIBAE), and the Asociación Colombiana de Electroquímica (ACEQ). Nearly 2,000 scholars from relevant research fields around the world attended the meeting.

In the report, Professor Pan Feng reviewed the academic achievements made by the School of Advanced Materials in the fields of energy storage as well as power batteries and materials in recent years and expressed his hope for future progress. He introduced his team’s research on the capacity and function of the anode materials used in the electric vehicle power battery industry, such as lithium iron phosphate and layered ternary materials. Besides, Pan also summarized the team’s progress on the formation mechanism of inorganic solid electrolyte interface (SEI) of the cathode carbon material and the correlation between the structure and the electrochemical window of the new super-concentrated electrolyte solution. During the report, Pan noted that in-situ quantitative monitoring of the formation process of the SEI at the carbon cathode at different electric potentials can be made possible by coordinating the electrochemical method with the electrochemical quartz crystal microbalance (EQCM) for weighing atoms/molecules, the atomic force microscope (AFM) for observing atomic scale morphology, and the differential electrochemical mass spectrometry (DEMS) for monitoring the composition of very trace gases. This work was published in the latest Nature Nanotechnology (DOI: 10.1038/s41565-018-0284-y, IF:37.5).
