Ion Storage Systems (ION), the battery technology company founded by ECS President Eric Wachsman, announced the initial closing of its $30 million Series A financing round. Clear Creek Investments, VoLO Earth Ventures, and Alsop Louie Partners led the investment. With the funding, ION will commission and qualify a battery cell manufacturing line capable of producing 10MWh/yr of safe, energy dense and versatile solid state batteries.

Ion Storage Systems

ION started in Dr. Wachsman’s University of Maryland chemistry lab with a $574,275 federal grant. The company’s high-energy dense, nonflammable solid state lithium metal batteries are safer, lighter, pack tighter density, tolerate greater abuse, and have reduced volume and weight. The new financing enables the company to launch a factory near Washington, D.C., and begin commercial production of the batteries. Aerospace and defense customers will receive the first commercial cells followed by development projects with multiple electric vehicle manufacturers, defense contractors, and consumer electronics companies.

Electrochemistry is the magic that binds together the many fields that excite Professor Bilge Yildiz, ECS Awarded Life Member and recipient of the 2012 ECS Charles W. Tobias Young Investigator Award—and invited speaker in the 241st ECS Meeting Symposium I05: Mechano-Electro-Chemical Coupling in Energy Related Materials and Devices 4. Prof. Yildiz was named a 2021 Fellow of the American Physical Society for “innovative contributions to understanding and manipulating ionic defects and charge transport at electro-chemo-mechanically coupled oxide interfaces and devices.” (more…)

The Electrochemical Society hosted Prof. Raphaële J. Clément’s live online webinar, “From order to disorder: NMR insights into ionic conduction in battery materials,” on October 27, 2021. Below are answers to questions posed during the presentation.

Raphaële Clément is an Assistant Professor in the Materials Department at the University of California, Santa Barbara (UCSB), U.S. She received her PhD in Chemistry in 2016 from the University of Cambridge, UK, working under the supervision of Prof. Clare Grey. Her doctoral work focused on the study of layered sodium transition metal oxide cathodes for Na-ion secondary batteries. She then joined Prof. Gerbrand Ceder’s group at the University of California, Berkeley (UC Berkeley), U.S., focusing on cation-disordered rock salt oxyfluorides for Li-ion battery applications. She joined the UCSB faculty in 2018. Her primary research focus is the development and implementation of magnetic resonance techniques (experimental and computational) for the study of battery materials and beyond, with a strong emphasis on operando tools. She is an Associate Editor for Battery Energy, a new open access journal by Wiley. (more…)

Be it improving energy density or cycle life or reducing cost, understanding the failure modes of batteries in a non-destructive mode is critical during the design, product development, and manufacturing of lithium ion batteries. Electrochemical impedance spectroscopy (EIS) provides the ability to access and decouple the failure modes based on the processes’ time scale. Analysis of recorded EIS can be done either through phenomenological modelling or equivalent circuit modelling, with each having its own pros and cons.

This webinar reviews the basics of applying EIS for understanding the phenomena in lithium ion batteries, the experimental details and protocols, and the types of models with a few case studies. (more…)
