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



In a previous post, Li-ion Battery Production, I reported how Sony decided to produce the initial Li-ion battery in the same manner as magnetic audio tape. This was because Sony had a surplus of magnetic tape production equipment and technicians, due to the shift in the market for recorded music from audio cassettes to compact disks. The production method helped deliver a significant initial improvement in performance over the nickel-cadmium



One of my favorite PBS series (by way of BBC) is Connections, written and presented by James Burke in 1979. Connections explores an “Alternate View of Change,” the subtitle of the series. Rather than a linear path guided by logic and the scientific method, technological progress is often the result of interconnected events driven by other individual or group motivations (e.g., profit, convenience, curiosity). The series illustrates how the interplay



Steve LeVine is the Washington, DC correspondent for Quartz. He writes about the intersection of energy, technology and geopolitics. In 2015, he published “The Powerhouse: Inside the Invention of a Battery to Save the World,” about the geopolitics of lithium-ion batteries. He closely follows and reports on advanced battery development, especially for electric vehicles. Last week Steve published an online article, “We are racing towards an electric-car future. Can battery



Rob Price’s March 14, 2016 Business Insider article, “Google’s smartwatch king has a 50-year vision for the future of Android Wear,” is crafted from his interview with David Singleton, Google’s director of Android Wear. Singleton’s ambitious vision is that, ““The smartwatch will feed you information before you ask for it, act as your ‘agent’ in the internet-connected world around you, and keep you healthy—even talking to your doctor before you



Mark Sullivan’s March 10, 2016 Fast Company article, “Apple Watch 2: How the World’s Best Smartwatch Might Makes Its Great Leap Forward,” takes a stab at answering two questions: How will the Apple Watch 2 be better than the first Watch? What will Apple add to the device to make it more useful and necessary to more people? First, Apple is expected to address shortcomings of its initial smartwatch, which



I recently attended a Gartner webinar and read articles in Business Insider and Fast Company that contemplate the future of the smartwatch. While each presents a slightly different perspective, they all agree that the smartwatch has to untether from the smartphone to fully realize its potential and accelerate market adoption. The Gartner webinar, presented on March 15, 2016, is titled “Wearables at the Peak of Inflated Expectations: Myths and Realities.”
