ECS Webinar: “Latest in In Situ/In Operando Characterization of Li-Ion Batteries”

Chock Karuppaiah Ph.D.
Founder and Chairman, Vetri Labs

Date: May 3, 2023
Time: 1300–1400h ET
Sponsors: BioLogic, TA Instruments – Waters


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 safety, improve 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 which 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.

Benefits of attending the webinar

Understand and appreciate the following:

  • Phenomena occurring in lithium ion batteries and how they affect safety, performance, and cycle life;
  • Time scales and the transitory nature of the above phenomena;
  • Techniques to characterize those transitory phenomena.
