4 INSTRUCTIONAL TEAM Dr. Greg Less, Senior Battery Manager, University of Michigan Battery Lab Greg Less is the Senior Laboratory Manager at the UMEI Battery Fabrication and Characterization User Facility, responsible for the day-to-day operation of the laboratory. Less received a doctorate in Chemistry from the University of Michigan. Prior to joining UMEI, he was a research scientist with battery companies T/J Technologies and A123 Systems. Prof. Bart Bartlett, Associate Professor of Chemistry Professor Bartlett s research interests are in inorganic materials, particularly investigating the correlation between atomic/molecular structure and electronic structure for the applications of photoanodes for solar water splitting and ion-insertion materials for electrical energy storage. Research in The Bartlett Group aims to exploit inorganic synthesis to control the composition and morphology of complex materials.

5 Dr. Tal Sholklapper, CEO and Co-Founder, Voltaiq. Inc. Dr. Tal Sholklapper is Voltaiq, Inc. CEO and Co-founder. Prior to founding Voltaiq, he worked as the lead engineer on a DOE ARPA-E funded project at the CUNY Energy Institute, developing an ultra low-cost grid-scale battery. Before joining CUNY, Dr. Sholklapper co-founded Point Source Power, a low cost fuel-cell startup based on technology he developed while at Lawrence Berkeley National Laboratory and UC Berkeley, where he also did his graduate work in Materials Science and Engineering. As a Materials Postdoctoral Fellow at LBNL, he successfully led the transfer of lab-scale technology to industry partners.

6 Brief presentations by: Prof. Jeff Sakamoto Jeffrey Sakamoto is an Associate Professor in the Department of Mechanical Engineering at the University of Michigan. Prior to joining UM, he was a faculty at Michigan State University for six years. Prior to that, he was a Senior Engineer at the California Institute of Technology, Jet Propulsion Laboratory for 7 years. He earned his Ph. D. (2001) in Materials Science and Engineering from UCLA. The Sakamoto group studies materials and manufacturing processes to develop new energy storage and biomedical technologies. In the context of advanced solidstate batteries, the recent work demonstrates that deliberate and controlled creation of Li-ion vacancies, in garnet-based crystal structures, is key in demonstrating fast-ion conductivity at room temperature. This ceramic material conducts ions as fast as state-of-the-art liquid Li-ion electrolyte membranes, perhaps enabling advanced solid-state batteries. Prof. Neil Dasgupta The Dasgupta group performs research at the intersection of nanotechnology, energy science, and manufacturing. Their goal is to develop scalable, low-cost techniques for the synthesis and assembly of nanostructures to address complex energy-related environmental challenges. Example applications include solar photovoltaics, artificial photosynthesis, catalysts, and batteries. Their research is highly interdisciplinary, drawing from influences in mechanical engineering, materials science, electrical engineering, physics and chemistry. Prof. Levi Thompson Professor Thompson s research focuses on the design and development of high-performance catalytic, electrocatalytic and adsorbent materials, and defining relationships between the structure, composition and function of nanostructured catalytic and electrocatalytic materials.
