Bolloré’s electric Bluecar, with novel solid-state batteries, coming to London
Electric car-sharing service Autolib has become a hit in Paris and two other French cities since its 2011 launch, and now boasts a fleet of over 3,500 EVs. Corporate parent the Bolloré Group also has a fleet of electric Bluebuses operating on Parisian streets, and has been working on bringing electric car sharing to Indianapolis… Read more »
PATHION’s superionic solid-state electrolytes point to more powerful and safer batteries
Solid-state electrolytes are the talk of the town these days. California-based PATHION has been working to commercialize solid electrolytes since its founding in 2012, building on its exclusive license from Los Alamos National Laboratories for a promising material called Lithium-Rich Anti-Perovskite (LiRAP). At the recent Materials Research Conference, PATHION presented two new superionic solid-state electrolytes built upon… Read more »
Stanford team improves potential of solid-state electrolytes by enhancing ionic conductivity
Solid-state electrolytes’ potential advantages in energy density and safety compared with conventional liquid electrolytes have made them the hottest topic in the battery world. However, there are several challenges to be overcome, including the low mobility of lithium ions in solid electrolytes. Now, a team of Stanford researchers have used ceramic nanowire fillers to enhance… Read more »
VW may use solid-state battery in its next-generation EV
Volkswagen has acquired a 5% stake in US battery startup QuantumScape, with an option to buy more, and it is evaluating the company’s solid-state battery tech with an eye to using it in VW’s next generation of EVs. Last November, Volkswagen Group CEO Martin Winterkorn said he saw “great potential” in solid-state batteries, which potentially… Read more »
Dyson invests $15 million in solid-state battery-maker Sakti3
Dyson, a manufacturer of high-tech vacuum cleaners, fans, restroom hand dryers and other nifty gadgets, has invested $15 million in Sakti3, a Michigan-based developer of solid-state battery technology. As CEO Ann Marie Sastry explained in a panel discussion last November, solid-state batteries theoretically offer higher energy density than current Li-ion designs, and could also be… Read more »
Beating the polysulfide shuttle to build a solid-state battery approaching theoretical capacity
The latest advance in lithium-sulfur technology comes courtesy of a research team from Samsung and the University of Rome, who have built a solid-state Li-S battery with a capacity (∼1600 mAhg−1) approaching the theoretical value and Coulombic efficiency approaching 99%. In a paper published in the Journal of The Electrochemical Society, the team concludes that… Read more »
Samsung invests in Solid-state battery-maker Seeo, sets sights on 400 Wh/kg
Seeo, a developer of lithium polymer batteries, has closed its largest funding round to date, adding Samsung Ventures to its list of investors. The company will use the new capital to accelerate the commercialization of its high-energy-density batteries. Seeo’s patented DryLyte solid polymer electrolyte is non-flammable and non-volatile, and delivers high energy density. Currently, Seeo… Read more »
Volkswagen buys piece of solid-state battery startup
Volkswagen has bought a five-percent stake in battery startup QuantumScape. Confidential sources told Bloomberg that the Volkswagen Group plans to complete tests of QuantumScape’s technology by mid-2015, and is considering using it in VW, Porsche and Audi vehicles. Closely-held QuantumScape, founded in 2010 by former Stanford University researchers, is working on solid-state batteries, which it… Read more »
Volkswagen sees “great potential” in solid-state batteries
In a speech at Stanford University last week, Dr Martin Winterkorn, Chairman of the Board of Volkswagen, said that he sees great potential in solid-state batteries, which could boost EV range to as much as 435 miles, representing a volumetric energy density of about 1,000 Wh/l. Replacing the traditional liquid electrolyte with a nonflammable inorganic… Read more »
