Conference: A sustainable rechargeable seawater battery

Speaker: S.T. Senthilkumar (Postdoctoral Researcher of the Electrochemical Processes Unit)

Short Bio

Senthilkumar received his Ph.D. in Physics at Bharathiar University, Coimbatore, Tamil Nadu (India) in 2014. Afterwards, he spent about a year in the Hong Kong Polytechnical University (PolyU), Hong Kong as Research Assistant. After that, he moved to Ulsan National Institute of Science and Technology (UNIST), South Korea for his postdoctoral research and worked there for about four years. These various research environments made him an expert in supercapacitors and seawater batteries. Since October 2019, Senthilkumar working as a postdoctoral researcher in Electrochemical Processes Unit of IMDEA Energy Institute. His research focuses on the development of membrane-free redox flow battery.


The development of inexpensive rechargeable batteries is expected to be enabled by developing new concepts or use of sustainable materials.  Likely, rechargeable seawater batteries (SWBs) have been designed for the storage of electrical energy that utilises seawater, as an infinite resource, as a source of the Na+ ion cathode. Seawater is an infinite resource for the Na element, which is the fourth most abundant element due to its availability in the form of Na+ ions in seawater. The concentration of Na+ ions in seawater is approximately 0.47 M; thus, it can possibly act as a Na+ ion source, like the cathodes used in rechargeable Na-ion batteries. In this presentation, I will talk briefly about the rechargeable seawater battery and their possible applications.
