As an innovator in advanced lithium-ion battery technology, Enovix follows the work of others in the field closely. Researchers have long tried to develop safe, high-energy batteries using lithium (Li) metal as the active anode material. A July 12, 2017 article by David L. Chandler in MIT News, “Study suggests route to improving rechargeable lithium batteries,” reports on a study that indicates smooth surfaces may prevent harmful deposits from working

Just over a year ago, I wrote a blog post titled THE APPLE WATCH: A Roadblock to Its Future. It referenced an article from Bloomberg Technology that began, “Apple Inc. has hit roadblocks in making major changes that would connect its Watch to cellular networks and make it less dependent on the iPhone.” The article concluded that, “The source of the delay is that current cellular chips consume too much

This is the fourth (and final) in a series of posts from the IEEE Spectrum article, “How to Build a Safer, More Energy-Dense Lithium-ion Battery,” authored by Ashok Lahiri, Nirav Shah, and Cam Dales of Enovix. The article describes how we use photolithography and wafer processing techniques to fabricate our 3D Silicon™ Lithium-ion battery. To fabricate the Enovix battery, we begin with a wafer of silicon that’s 1 millimeter thick. This doesn’t

Power Electronics is a Penton publication. Its expert editors report on the engineering, design and integration of power electronic system applications, such as battery-powered systems, consumer, commercial and industrial power electronic systems; and power systems for electric and automotive transportation. In an August 2, 2017 article, Sam Davis, editor-in-chief, writes that, “Large-scale adoption of wearable devices will depend on availability of two important technologies: improved batteries and higher density transistor

This is the third in a series of posts from the IEEE Spectrum article, “How to Build a Safer, More Energy-Dense Lithium-ion Battery,” authored by Ashok Lahiri, Nirav Shah, and Cam Dales of Enovix. The article describes and illustrates how thermal runaway can occur in a conventional Li-ion battery. The polymer separator is an inactive material and has to be physically longer and wider than the electrodes to make sure

This is the second in a series of posts from the article, “How to Build a Safer, More Energy-Dense Lithium-ion Battery” authored by Ashok Lahiri, Nirav Shah, and Cam Dales of Enovix. Following is an excerpt from the article regarding how our 3D cell architecture enables us to incorporate a 100% silicon anode. Our flat-cell architecture can take full advantage of a number of advances in electrode chemistry. To understand

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 first three posts in this series described how Dr. Richard Swanson started SunPower, how T.J. Rodgers forever changed SunPower’s future, and how Cypress production processes helped SunPower combine innovative technology with low-cost, high-volume production to transform the solar industry. The final post illustrates the results of these events. Creating $7.6 Billion of Shareholder Value SunPower began commercialization of its high-efficiency solar panels in 2004. Revenue quickly grew from $10.9

In the second post of this series, I described how a chance encounter between two old college classmates forever changed SunPower’s fortunes, and that semiconductor and solar cell production had little in common. This post describes how Cypress process controls and production innovations were implemented to accelerate learning and achieve low-cost, high-volume production of high-performance solar cells. The Cypress Years, Part Two: Processes, Autoline and Accelerated Learning Chuck Stone was

In the first post of this series, I described how Dr. Richard Swanson, a professor of electrical engineering at Stanford University, founded SunPower and developed innovative, high-performance solar cells between 1985 and 2001. This post describes how a chance encounter with an old college classmate would forever change SunPower’s fortunes. And that semiconductor and solar cell production have little in common. The Cypress Years, Part One: Semiconductors and Solar Cells Cypress
