Bio
Dr. Subhas Chalasani is an esteemed member of the Research and Development team at East Penn Manufacturing, USA. As the company continues to explore new advancement in lead-acid batteries, Dr. Chalasani brings 32 years of R&D experience in both lead-acid and lithium-ion technology to the program. Dr. Chalasani has successfully led other prominent battery development programs at companies including Exide Industries Ltd., Boeing, General Motors, and AT&T Bell Labs. A Ph.D. in Electrochemistry along many patents and publications in battery and battery management designs support his well-respected career and highly valued work.
East Penn Manufacturing Co. (EPM) has been proactively supporting CRADAs (Cooperative Research and Development Agreement) in collaboration with Argonne National Laboratories (ANL), where lead battery chemistry has been researched using state-of-the-art facilities. EPM has been supplying lead electrodes and specially designed minicells to support the CRADA activities at ANL. In this presentation, the results of various electrochemical tests performed at EPM, on single electrodes, as well as on 2V minicells will be presented. These results will be compared with that of 12V batteries, to see how they can predict the battery behavior. The electrochemical tests include cyclic voltammogram and electrochemical impedance techniques. Both the advantages and the short comings of the single electrode and minicell tests, including HRPSoC cycling, will be highlighted. The failure mode analysis of the batteries will also be discussed.
