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



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
