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 Enovix model for the development and production of our 3D silicon lithium-ion cells closely resembles the SunPower model for low-cost, high-performance solar cells. This is due to our relationships with Cypress Semiconductor, and, especially, with T.J. Rodgers. I recently had an opportunity to learn more about the history and legacy of SunPower, including interviews with T.J. Rodgers, founder of Cypress Semiconductor, and with Chuck Stone, Enovix vice president of

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

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

Last month I wrote about Samsung recalling about 2.5 million Galaxy Note 7 smartphones. At the time, I noted that the Samsung predicament was just the latest in a string of Li-ion battery detonations that had affected a wide-range of mobile products, including hoverboards, portable computers and even large-passenger aircraft. However, the Samsung situation has now become a fiasco, at considerable cost to the company. But before I elaborate on

Last week 4,000 research scientists and engineers, including many specializing in battery technology, convened for PRiME 2016 at the Hawaii Convention Center in Honolulu. This year’s conference marked the 25th anniversary of the lithium-ion (Li-ion) battery’s commercialization in 1991. Pioneering scientists who helped transform Li-ion technology into the engine that powers today’s mobile devices delivered several symposia presentations. John Goodenough, whose discovery of the lithium cobalt oxide cathode paved the
