Hilton village (one of the meeting place)
The Electrochemical Society (ECS) is a professional association based in the United States. The 230th ECS meeting was held in Hawaii named “The 2016 PRiME meeting”. It is a forum for sharing the latest scientific and technical developments in electrochemistry and solid-state science and technology. Scientists, engineers and industry leaders come from around the world to attend the technical symposia, poster sessions, professional development workshops, networking opportunities and social events. The meeting was held right in the heart of downtown Honolulu, which is the perfect setting to really immerse oneself in all.
In this meeting, I present my research in the symposium E-03, which is about molecular structure of the solid-liquid interface and its relationship to electrodeposition, on October 5th at 16:40-17:00. My presentation was titled as “In-situ Raman spectroscopy study on the preferential adsorption of electrolyte species on electrode surface of Lithium ion battery”. The Solid-electrode interphase (SEI) plays an important role in the performance of Li-ion battery, while the mechanism of SEI was still unclear. We employed in-situ Raman spectroscopy and surface-enhance Raman spectroscopy (SERS) to investigate the electrode/electrolyte interfacial process. We focused on the reaction of two conventional electrolyte solvents, PC-based electrolyte and EC-based electrolyte. The results suggested that Li2CO3 would be generated from PC-based electrolyte, but nearly no generation in EC-based electrolyte. The products of Li2CO3 may responsible for the ineffective SEI formation from PC-based electrolyte. The Li2CO3 generation mechanism was analyzed to be the more 2-electron reduction pathway of PC, which is caused by the low molarity of PC at the edge of graphite.
Beautiful beach in Hawaii
Attending this meeting is a precious experience to me. It made me to understand my merit and disadvantage. Besides, I learned a lot from the many presentations provided by the other experts in the field of Lithium ion battery. This is a very good chance for a student to join an international conference, communicate with other researchers and gain ideas through the plenty of lectures, presentations and posters. With these, I am truly grateful to Marubun Research Promotion Foundation for the travel support granted to me.
