From cutting-edge cars to appliances in the home and ones you wear on your wrist, battery technology is evolving rapidly, racing to keep up with consumer and industry demands. Understanding battery chemistry is essential in battery research that could hold the key to enhancing both technological efficiency and how we live our lives.

Understanding the fine details of battery performance is crucial. For example, structural evaluation of the electrode during lithation and delithation is fundamental to battery function. New technology like the Battery Cycler Microcalorimeter Solution offers structural evaluation from in-operando real-time electrochemical and thermal signals to empower new discoveries. This webinar will cover these exciting new developments. We’ll also pose your questions to the speakers, who will offer their expert insights on everything from general thoughts on where batteries are headed to the fine details you’re exploring in your career.

During this one-hour webinar, the speakers will also present a case study, showing how to identify phase changes of silicon anode and quantify parasitic reactions to gain insight for cycling dependence in Li-Si structure and energy efficiency of Si. Join us to learn how to gain novel insights into battery materials and cell behaviour through isothermal microcalorimetry.

By the end of the webinar you will have learned to:

• Evaluate new battery chemistries with in-operando microcalorimetry

• Understand battery materials’ structural and chemical changes

• Obtain thermodynamic parameters and parasitic heat measurements

Larry Krause, founding researcher, Cyclikal

Larry Krause received a PhD in physical chemistry from the University of Illinois in Chicago, USA. After a post-doctoral appointment at Argonne National Labs, USA, he joined 3M in 1982. Following several assignments in technology areas involving electrochemistry and electrochemical engineering, in 1993 Larry became involved with 3M’s entry into the United States Advanced Battery Consortium. This project involved the development of a 30kWh polymer electrolyte battery. The consortium was composed of 3M as the prime contractor, Hydro-Quebec and Argonne National Laboratory as co-partners. In 1996, Dr, Krause started an internal 3M project in lithium-ion chemistry. Larry is a founding member of the experimental consulting firm Cyclikal, which provides unique analytic experimental techniques for lithium-battery technologies.

Vincent Chevrier, founding researcher, Cyclikal

Vincent Chevrier completed an MSc and PhD in Physics at Dalhousie University, Canada, with professor Jeff Dahn and a post-doc at Massachusetts Institute of Technology, USA, with professor Gerbrand Ceder. Vincent joined 3M in 2010 and focussed on the optimisation, production and scale up of silicon-based materials for high energy density lithium-ion batteries. Topics of interest included material design and characterisation, electrode design, cell optimisation, prelithiation, cell failure modes, and high precision coulometry and calorimetry. In 2018, Vincent and Larry Krause founded Cyclikal, a battery research and consulting company with a focus on high precision cycling and calorimetry. In 2021, Vincent additionally took on the role of chief technology officer at Trion to lead the development and commercialisation of a portfolio of silicon-based materials. Vincent has 30 academic papers, with over 9000 citations.
