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
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
A Roadblock to Its Future
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.
As I noted in the previous blog post, LI-ION BATTERY MARKET: 1995–2015 Growth and Drivers, Avicenne Energy, a market research and consulting firm, publishes a comprehensive report each year, “The Worldwide Rechargeable Battery Market.” The graph shows the actual growth of Li-ion battery use for portable electronics and electric vehicles since 2000, and the projected growth through 2025. The Rechargeable Battery Market (source: Avicenne Energy) Between 2000 and 2015, the
Avicenne Energy is a market research and consulting firm that has established a well-regarded reputation for coverage of the battery market. Each year Avicenne publishes a comprehensive report, “The Worldwide Rechargeable Battery Market.” The Avicenne graph below shows how Li-ion battery market size and share grew from 1995 through 2015. An earlier post, LI-ION BATTERY PRODUCTION, described how Sony commercialized the first lithium-ion (Li-ion) battery in 1991 to help drive
Frost & Sullivan is a global research and consulting organization that focuses on identifying “The Next Big Things” in the industries it covers by understanding the interplay between industry convergence, mega trends, technologies and market trends. According to a Frost & Sullivan report, Implications of Mega Trends on Batteries, “Rapid advances in wearable devices and the Internet of Things (IoT) are being mirrored by breakthrough innovations in battery technologies.” The
The Enovix 3D cell architecture also provides several safety features not obtainable with a conventional Li-ion battery structure (see illustration below). Safety features of Enovix 3D cell architecture (source: Enovix Corporation) The Enovix cell architecture allows for a ceramic separator that tolerates higher temperatures than the polymeric separator in a conventional Li-ion battery. Excess capacity in the Enovix patented silicon anode reduces risk for lithium metal plating during overcharge conditions.
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
