Lithium ion battery, magnets and thermoelectric devices for sustainable transportation

Friday, 26 August 2016, 11:00-12:30
Institute of Nanotechnology Seminar room 0-167
Talk given by Prof. Raghavan Gopalan Associate Director International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI) IITM Research Park Chennai, India Abstract: Battery, fuel cells, magnets, thermoelectric materials form important components for energy saving devices in automotives, and energy storage applications. It is predicted that in the next ten years major changes will be required for sustainable transportation energy. Current research on energy materials demonstrate that well defined process- chemistry map strategy is required to tune the properties for matured Materials Technology. In recent times, the progress in Li-ion battery technology, especially among the electrode materials for high charge / discharge capabilities, is a great boom to Electric Vehicle(EV) / Hybrid electric vehicle sectors. One of the concerns with well known LiFePO4 cathode material is on how to enhance its electronic conductivity and this demands development of conducting coating on the particle surface and powder size reduction or go for new chemistry electrode materials. ARCI has established lithium ion battery fabrication line for electric vehicle application and has developed assorted prototype cells (3-10 Ah) using LiFePO4 and graphite electrodes. Establishment of the facilities and development of the prototype of cells will be discussed in details along with cathode materials for large scale fabrication technology during my presentation. In EV technology, apart from battery, the other major component of energy saving part is the motor which involves new magnetic materials development and a brief about this research will be touched upon in this presentation. In conventional automobile, an effective way of utilizing the excess waste heat of fuel combustion for vehicular operation will result in many benefits both from economic and environmental point of view. A thermoelectric generator (TEG), which converts the heat into electricity, is one of the ideal methods for this purpose. However, the efficiency of TEG available as on today is very low (around 5-8%), and hence the applications are limited. ARCI’s effort in thermoelectric generator programme for automobile applications will also be discussed.
