He received the university-wide (one per year) Outstanding Graduate Teaching Award in 2012, the Battery Division Research Award from the Electrochemical Society in 2014, the Distinguished Alumnus Award of the Indian Institute of Technology Madras in 2015, the Billy and Claude R. Hocott Distinguished Centennial Engineering Research Award in 2016, and the Da Vinci Award in 2017. He is a Web of Science Highly Cited Researcher in 2017.
This presentation will focus first on developing a fundamental understanding of the factors that control the capacity fade and air-reactivity, employing samples with secondary particle sizes of ~ 10 microns and advanced bulk and surface characterization methodologies. In-depth understanding obtained with cathodes with Ni contents of as high as 94% and graphite anodes retrieved from full cells before and after thousands of cycles based on a combination of characterization techniques, viz., X-ray photoelectron spectroscopy, time-of-flight – secondary ion mass spectroscopy, and high-resolution transmission electron microscopy, will be presented. Utilizing the understanding gained, the presentation will then focus on the development of layered oxide compositions with capacities of > 220 mAh/g.
