Dr. Abhik Banerjee received his B.Sc. and M.Sc. in chemistry from University of Calcutta. He did his Ph.D. in 2015 from National Chemical Laboratory, India.  He was then postdoctoral scholar at Ulsan National University of Science and Technology, South Korea. He is currently a postdoctoral scholar in the Department of Nano-engineering at UCSD, working in the “Laboratory of Energy Storage and Conversion” under Prof. Ying Shirley Meng. His research interest includes the design principle and interfacial charge transfer limitation of solid-state electrolytes for Li and Na-ion batteries.

Dr. Thomas Brenner

email: tmbrenner at

Thomas received his B.A. in physics from Carleton College in Northfield MN in 2009. He completed his PhD in Applied Physics at the Colorado School of Mines in 2014, with a thesis exploring monolayer modification of metal oxide contacts in organic solar cells. Following his PhD, Thomas joined the groups of Gary Hodes and David Cahen at the Weizmann Institute of Science, Israel under an Alternative and Sustainable Energy Initiative (AERI) post-doctoral fellowship. At Weizmann, Thomas studied charge transport and formation chemistry in halide perovskite semiconductors. Thomas joined the LESC as a post-doctoral scholar in August 2016. His focus is on interface effects in all-solid-state batteries and advanced scanning electron microscopy characterization techniques.

email: xuw079 at

Xuefeng obtained his M.S. in 2013 and Ph.D. in 2015, both from the Institute of Physics, Chinese Academy of Sciences (IOP, CAS). His interests are focused on the high-energy storage beyond Li-ion batteries, such as Li-S batteries, Na-ion batteries, Li-air batteries and Li-metal. His research in the IOP, CAS involved in exploring new electrode materials, designing nano-architecture, clarifying atomic structure, investigating intercalation mechanism and improving electrochemical performance of the Li-S and Na-ion batteries. He is also interested in the two-dimensional materials for the rechargeable batteries, such as graphene, layered oxides, transition metal dichalcogenides, Mxenes and so on. Currently, he is focusing on the understanding of catalytic mechanism for Li-air batteries as well as the growth mechanism and protection of Li metal.



Dr. Bao Qiu

email: qiubao at

Bao obtained his Ph.D. in 2016 from Ningbo Institute of Materials Technology & Engineering (NIMTE), Chinese Academy of Sciences. In his Ph.D., his interests were focused on the Li-rich layered oxide cathode materials for high-energy Li-ion batteries. His researches are also involved in the high-capacity oxide cathode materials for Li-ion batteries and high-efficiency phosphor materials for white light-emitting diodes. Currently, he is interested in the design of lithium ion battery electrode cathode oxide materials and their structure−electrochemical property relationships.
