IEEE Spectrum recently published an article, “How to Build a Safer, More Energy-Dense Lithium-ion Battery,” authored by Ashok Lahiri, Nirav Shah, and Cam Dales of Enovix. It describes how our patented 3D cell architecture and silicon wafer production produces a lithium-ion battery with increased energy density and improved safety. I’ll be serializing key parts of the article over the next few posts. Following is the first excerpt from the IEEE

The U.S. Department of Energy’s Argonne National Laboratory has named Venkat Srinivasan the next director of the Argonne Collaborative Center for Energy Storage Science (ACCESS). ACCESS is a collaborative of scientists and engineers from across Argonne that helps public and private-sector customers create energy storage solutions through multidisciplinary research. Venkat holds a special place at Enovix. He was a technical advisor to the Enovix co-founders at the inception of the

The Institute of Engineering and Technology (IET) traces its heritage to 1871. Today its mission is to, “inspire, inform and influence the global engineering community, supporting technology innovation to meet the needs of society.” E&T (Engineering and Technology) is the IET’s award-winning monthly magazine and associated website for professional engineers. E&T recently published an article by Holly Cave titled, “Charging ahead: the bid for better EV batteries.” The article’s premise

The last few months of 2016, I wrote several posts about lithium-ion safety issues. This included reporting on the cost of the Samsung Galaxy Note 7 failure, and that it was just the latest in a series of high-profile lithium-ion battery mishaps. Previously, I had written about how Li-ion battery safety problems were the legacy of Sony’s decision to repurpose audio cassette magnetic recording tape equipment for battery production in

On Friday, November 18, I had the privilege of participating on a panel at the 2016 Bay Area Battery Summit: Energy Storage at Inflection Point. The one-day summit, organized by CalCharge and SLAC National Accelerator Laboratory, addressed fundamental questions about energy storage Research, Development, Demonstration and Deployment (RDD&D). I was a member of the “Innovation in Energy Storage Panel,” moderated by Brian J. Bartholomeusz, Executive Director Innovation Transfer at Stanford

If this is the first post you’ve read in this series, BUILDING A BETTER BATTERY, you may want to take a look at Parts One, Two, Three, and Four for complete context. A Better Business Model Enovix was conceived with a conviction that building a better battery involves more than just technology; it requires a new business model with ownership of intellectual property (IP) and direct production control. Since 2012,

If this is the first post you’ve read in this series, BUILDING A BETTER BATTERY, you may want to take a look at Parts One, Two and Three for complete context. In the prior post, I outlined the Enovix co-founders’ vision for building a better battery. It’s differs from that of many other battery startups in several aspects. First, rather than pursue a novel chemistry, Enovix sought to unlock the

BUILDING A BETTER BATTERY is a series that started in response to a reader’s comment about the length of time it’s taking to commercialize our 3D Silicon™ Lithium-ion Rechargeable Battery. Part One benchmarked the most recent battery breakthrough, and presented an explanation as to why there has been no significant advancement in battery performance over the past quarter-century. Part Two benchmarked product breakthroughs essential to modern mobility—ICs, LEDs and LCDs—that

This series started in response to a reader’s comment about the length of time it’s taking to commercialize our 3D Silicon™ Lithium-ion Rechargeable Battery (Enovix was founded in 2007). Part One described Sony’s 12-year pursuit to develop and commercialize a lithium-ion (Li-ion) battery in 1991. It also presented an explanation as to why there has been no significant advancement in battery performance over the past quarter-century. The second post in

I’m going to deviate from the series I began with my last post to address the timely topic of battery safety. I’ll return to why it’s taking so long to build a better battery next week. Last week Consumer Reports published an online article about Samsung Note 7 smartphones catching fire while charging. Over the Labor Day weekend, major media, including The Wall Street Journal, reported that “Samsung Electronics is
