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 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

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

I’ve written several posts over the past two months about the Galaxy Note 7 battery fires that led Samsung to remove it from the market. In my prior post, I reported, from a Wall Street Journal article, that “investors have shaved off roughly $20 billion in Samsung’s market value. The company has said the recall would cost it $5 billion or more, including lost sales.” The big question now is

It’s been a rough month for Li-ion smartphone batteries. I’ve chronicled the unfortunate events Samsung has experienced with its Galaxy Note 7 smartphone in prior posts: Samsung is Just the Latest and The Cost of Battery Failure. The October 24 issue of The Wall Street Journal provides the latest update in its article, “The Fatal Mistake That Doomed Samsung’s Galaxy Note.” Fear: Samsung Incident Triggers a Wide-Ranging Inquiry into Li-ion

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

Last week’s post, THE APPLE WATCH: A Roadblock to Its Future, produced a comment on LinkedIn from a reader regarding the time it’s taking to commercialize our 3D Silicon™ Lithium-ion Rechargeable Battery. It read, in part, “You guys have been in business since 2007 so where is it, bring it on.” It’s a fair question, but one without a short or simple answer. So I’m going to devote several posts

In June, I posted a series of three perspectives on the future of the smartwatch. While each has a slightly different viewpoint, they all agree that the smartwatch has to untether from the smartphone to fully realize its potential and accelerate market adoption. The second post in the series, A GREAT LEAP FORWARD: Don’t Leave Home Without It, focused on the future of the Apple Watch. It noted that the

The previous post, LI-ION BATTERY MARKET: 2015 – 2025 Projections, included a graph from the Avicenne Energy report, “The Worldwide Rechargeable Battery Market.” The graph showed that Li-ion battery use for portable devices is expected to double between 2015 and 2025. An important factor will be the growth of wearable devices. IDTechEx is an analyst and consulting firm that conducts detailed examinations of emerging technologies based on extensive primary research.

A previous post, Li-ion Battery Disadvantages, examines how the original magnetic recording tape production paradigm for the Li-ion battery has created performance limitations and safety issues. In contrast to the “jelly roll” structure of a conventional Li-ion battery, derived from magnetic recording tape production techniques, Enovix uses 3D cell architecture (see illustration below). Cross-section of Enovix 3D cell architecture (source: Enovix Corporation) The Enovix 3D cell is inherently rectangular. This
