The latest in in situ/in operando characterization of Li-ion batteries

With electrification of transportation becoming critical for meeting the decarbonization goal, lithium-ion batteries need multifold upscaling. This increase in scale demands next-level understanding in the depth of phenomena occurring in the batteries. This is critical to enhance the safety, improve the performance, and reduce the total cost of ownership.

Being electrochemical in nature, the resultant performance of lithium-ion batteries culminates from a series of interrelated complex phenomena that are dynamic in nature. The phases that get formed during these dynamic phenomena are metastable in nature and thus difficult to access. Hence it becomes imperative to characterize these transitory phases as they happen. To enable this, several new techniques have been developed that help us to understand the changes in the bulk material, electrode/electrolyte interface, and gas-evolution aspects. These techniques span the use of varying radiations including X-ray, electron, neutron, optical and scanning probes.

This webinar focuses on an overview of each of the major techniques and what we can learn from each technique.

An interactive Q&A session follows the presentation.

Chockkalingam (Chock) Karuppaiah has more than 25 years of electrochemical experience in the energy and technology sectors. Prior to founding Vetri Labs, Chock was the vice-president of Stack Engineering at Bloom Energy, professor at Case Western Reserve University, and fundamentals team manager at Plug Power. While at Bloom, he led the product design, process development, and manufacturing scale-up of seven product generations. His technical work includes the development of solid-state batteries, polymer electrolyte fuel cells, solid-oxide fuel cells, and flow batteries. Recently, he joined Ohmium as chief technology officer where he will help scale their electrolyzer technology for the generation of green hydrogen. He has authored 25 patents in the area of electrochemical technology and devices.
