The last decade has seen increased penetration of electrified modes of transport, with vehicles ranging from hybrid-electric vehicles (HEV) to plug-in-hybrid-electric vehicles (PHEV) to battery-powered full-electric vehicles, becoming common on the roads. This increased penetration is a result of significant advances in battery technology, specifically, in improvements in the class of systems referred to as "lithium-ion" batteries. It is hoped that in the next decade, there would be further penetration of these alternate vehicles on the road. However, for this to occur, significant improvements in today's batteries are needed, especially related to the cost.

This talk will provide an overview of the status of lithium-batteries for use in HEV, PHEV, and electric vehicle (EV) applications and describe what is needed to ensure widespread penetration of electrified vehicles. The talk will then describe the efforts now underway to bridge the gap, both in development of new technologies and in manufacturing of these systems with an eye on reducing the cost. Emphasis will be placed on describing the challenges in the various approaches with the aim of educating the audience on the possible evolution of technology in the future.

Speaker Biography

Venkat Srinivasan Ph.D., is head of the Energy Storage and Distributed Resources Department at the Lawrence Berkeley National Lab (LBNL). Dr. Srinivasan also serves as the Acting Director of the Batteries for Advanced Transportation Technologies (BATT) Program and Deputy Director of the recently announced Energy Storage Hub, titled Joint Center for Energy Storage Research (JCESR). Dr. Srinivasan's research interest is in developing the next-generation batteries for use in vehicle and grid applications. At present, he has projects focused on studying the degradation and performance limitations in advanced lithium-ion cathode and anode materials and on developing high power, low-cost flow batteries for use in stationary energy-storage applications. Dr. Srinivasan received his bachelors in Electrochemical Engineering from the Central Electrochemical Research Institute (CECRI) in Karaikudi, India, in 1995 and his Ph.D. from the University of South Carolina in Chemical Engineering in 2000. His thesis topic included various aspects in electrochemical capacitors and the nickel hydroxide electrode. Dr. Srinivasan then worked as a research associate at the Department of Mechanical and Nuclear Engineering at Penn State University for 18 months where he was involved with projects in lead-acid, alkaline, Ni-MH, and Li-ion batteries. Subsequently he moved to the Lawrence Berkeley National Laboratory/University of California at Berkeley as a postdoc working on modeling iron phosphate-based Li-ion cells. Dr. Srinivasan joined the scientific staff at LBNL in 2003.
