Materials Engineering for Advanced Batteries and Recycling Spent Li-ion Batteries

Ganguli Babu

Department of Materials Science and NanoEngineering

Rice University

Abstract: The state-of-art Li-ion batteries have been at the forefront among various energy storage technologies due to their uniqueness of lightweight and high energy density. However, if the future energy needs are taken into account, especially energy density, power density, cost-effectiveness, etc., then the currently available electrode and electrolyte materials and their interphases will need significant modifications at a fundamental level, and thus considerable opportunities exist for scientific advancements in materials science and technological developments. Based on these challenging problems, we have been working at the innovative front of materials design and development for advanced energy storage systems such as Li-S batteries. This talk will discuss the various strategies with respect to electrode and separator materials engineering to mitigate polysulfide dissolution and thus boost the performance of Li-metal free sulfur battery configuration that simultaneously provides high energy density and safety. On the other hand, the consumption of Li-ion batteries (LIBs) for use in the transportation and consumer electronic sectors continues to grow, so does the pile of battery waste accompany the mass production of these Co-rich devices. Posing a threat not only economically but also to human health, these wastes have incited research in battery recycling. Herein, I will also discuss the recycling process for spent LIBs to sustainably extract and reuse expensive metals such as lithium, cobalt, Nickel, Aluminum, and Copper.


Short Bio: Dr. Babu Ganguli is working as a Research Scientist in the Department of Materials Science and Nanoengineering at Rice University since July-2016. He received his Master’s in Chemistry from Central College, Bangalore University, and his Ph.D. from CSIR-Central Electrochemical Research Institute. Babu has over 13 years of industry and academic experience in energy storage systems (Supercapacitors, Li-ion, Li-S, and Na-ion batteries). With three research grants as a PI from both federal and industry funding agencies, he has published over 58 research articles in reputable international journals including Nature Energy, JACS, Science Advances, Advanced Materials, and filed 12 patents in the field of materials chemistry and engineering. His research interests are lie in the interdisciplinary field of materials science and electrochemistry, using an engineering and sustainable perspective to fabricate next-generation energy storage and conversion systems.
