Battery Safety Science Webinar Series - Sodium-ion Battery: From Materials to Cell Development
Please join us on February 17, 2021, for this one-hour battery safety science webinar during which Dr. Palani Balaya, Associate Professor, Department of Mechanical Engineering, Faculty of Engineering for the National University of Singapore will discuss, "Sodium-ion Battery: From Materials to Cell Development."
Sodium-ion batteries are considered to be a cheaper alternative to lithium-ion batteries on account of the globally abundant sodium resources. To achieve commercialization, sodium-ion batteries need to obtain good cycling performance and energy density with enhanced safety. Dr. Palani Balaya will present selected examples of commercial type Na-ion cells using polyanion and O3 type cathodes against hard carbon anode and non-flammable glyme-based electrolyte. Further supportive information on SEI formation and its characteristics obtained by Attenuated Total Reflection-Fourier-Transform Infrared Spectroscopy, Electrochemical Impedance Spectroscopy, and Differential Scanning Calorimetry will be presented. The pros and cons of the developed sodium battery chemistries in the format of 18650 Na-ion cells will be presented and discussed in terms of the heat generation and associated internal resistance.
Just after his stay at Max Planck Institute for Solid State Research, Stuttgart (2001-2006) with Prof. Joachim Maier, Dr. Palani Balaya joined the Faculty of Engineering, National University of Singapore (NUS) as an Assistant Professor in 2007. Since 2014, he has worked as an Associate Professor at NUS. His research area includes lithium-ion battery and sodium-ion battery. He served as a Topical (Battery, Fuel Cell, Capacitor) Editor for Journal of Solid State Electrochemistry (2013-2017), was elected as an Academician by the World Academy of Ceramics, Italy (2019), and elected as a Fellow of the American Ceramic Society (ACerS) in 2019. He was recognized as an ACerS Global Ambassador in 2016, is a recipient of the Global Star Award (2015) from ACerS, and won the Late Shri Har Mahandar Singh Chhatwal Memorial Award (2015) from the Indian Ceramic Society. He served in Inter-governmental Panel on Climate Change as a Co-ordinating Lead Author for preparing a Special Report on Renewable Energy Sources and Climate Change Mitigation in 2011.
