Dyson Will Spend $1.4 Billion, Enlist 3,000 Engineers To Build a Better Battery (digitaltrends.com)
An anonymous reader quotes a report from Digital Trends: Among the 100 new products the company founder James Dyson wants to invent by 2020, the greatest investment in people and money is to improve rechargeable lithium-ion batteries, as reported by Forbes (Warning: paywalled). And Dyson is not planning incremental improvements. His opinion is that current Li-ion batteries don't last long enough and aren't safe enough -- the latter as evidenced by their propensity to spontaneously catch on fire, which is rare but does happen. Dyson believes the answer lies in using ceramics to create solid-state lithium-ion batteries. Dyson says he intended to spend $1.4 billion in research and development and in building a battery factory over the next five years. Last year Dyson bought Ann Arbor, Michigan-based Sakti3, which focuses on creating advanced solid-state batteries, for $90 million. The global lithium-ion battery market accounts for $40 billion in annual sales, according to research firm Lux as cited by Forbes. Dyson's company (which is an accurate description since he has 100-percent ownership) currently employs 3,000 engineers worldwide. He intends to hire another 3,000 by 2020. Their average age is 26. Dyson values young engineers, saying, "The enthusiasm and lack of fear is important. Not taking notice of experts and plowing on because you believe in something is important. It's much easier to do when you're young." -
Supercapacitor-On-a-Chip Now One Step Closer (ieee.org)
schwit1 writes: In 2010 Spectrum reported a new approach for creating chip-scale supercapacitors on silicon wafers, proposed by researchers at Drexel University in Philadelphia and the Universite Paul Sabatier in Toulouse, France. In an article published in Science, the researchers described how to make supercapacitor electrodes from porous carbon that could stick to the surface of silicon wafers so that they could be micromachined into electrodes for on-chip supercapacitors. Now the same team has finally succeeded in doing just that. In a paper published in this week's Science, researchers from the two initial teams report creating efficient porous carbon electrodes that really stick to the surface of a silicon wafer. They made layers of porous carbide derived carbon (CDC) that are completely compatible with all treatments used in the semiconductor industry, says Patrice Simon, a researcher at Universite Paul Sabatier who has researched porous CDC electrodes over the last ten years and co-authored both the 2010 and this week's paper in Science.
