Join us for an exciting webinar organized by the Maritime Battery Forum and presented by Judy Jeevarajan, Ph.D., Vice President and Executive Director Electrochemical Safety Research Institute (ESRI) UL Research Institutes on Sodium-ion batteries!

Sodium-ion cells and batteries are gaining traction in the commercial market. ESRI's studies focus on characterizing the performance and safety of cells and modules of this chemistry. Sodium-ion cells are currently being manufactured with various cathode and anode materials as well as electrolyte compositions and it is imperative to understand how these affect both performance and safety trends of this chemistry.

Performance studies include cycle life testing at different rates and different temperature environments and safety tests included overcharge, over-discharge, short circuits and external heating tests. Tests were carried out at the single cell and small module levels. Gas and particulate emission characterizations were also carried out at the single cell level. The results of the studies will be presented.
