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 »
ORNL team demonstrates high-voltage solid-state battery with impressive cycle life
Researchers at the Oak Ridge National Laboratory have demonstrated a solid-state high-voltage (5 V) lithium battery with an extremely long cycle life (10,000 cycles) and high Coulombic efficiency (99.98%). The solid electrolyte enables the use of high-voltage cathodes and lithium anodes with minimal side reactions. The energy stored in a battery of a given size… Read more »
Could Sakti3 build GM’s 200-mile battery?
After years of operating in secrecy, battery startup Sakti3 has been much in the news lately, the subject of feature articles in Scientific American and Fortune (via Green Car Reports). The Ann Arbor company, founded in 2008 by Ann Marie Sastry, has developed a solid-state electrolyte, which could eliminate some of the drawbacks of liquid electrolytes, including… Read more »
Sakti3 demonstrates impressive energy density with solid-state battery cells
For a few years, battery insiders have been talking about a startup company called Sakti3. The University of Michigan spin-out has received millions in funding from backers including Khosla Ventures and GM Ventures. Until recently, the company has been pretty secretive, but this week CEO Ann Marie Sastry told Scientific American that the company’s prototype… Read more »
Toyota researchers develop all-solid-state Li-ion batteries
As Toyota plans to bring a fuel cell vehicle to market in 2015, its researchers continue to work on next-generation battery technologies. In a presentation at the International Meeting on Lithium Batteries in Como, Italy, Dr. Hideki Iba from Toyota’s Battery Research Division and Dr. Chihiro Yada from Toyota Motor Europe’s Advanced Technology Group noted… Read more »
Wildcat’s new copper fluoride cathode material offers 2.5x more capacity than today’s battery tech
The current generation of lithium-ion battery materials is quickly approaching its theoretical limit. In commercial layered oxide cathodes, like the popular nickel-manganese-cobalt (NMC), there is only one lithium ion for every metal. So, the most energy you could possibly store with those materials is one full lithium in and out, or about 300 mAh per… Read more »
US/Chinese/Korean research team details the challenges of Li-air battery research
Lithium-air batteries are widely expected to be the next big thing – more than 300 research papers have been published on the topic in the past 3 years. Li-air has the potential to deliver far more energy density than current lithium-ion technology. A new review in the ACS journal Chemical Reviews sums up the current… Read more »
ORNL researchers extend battery life with dual-function electrolyte
Researchers at the DOE’s Oak Ridge National Laboratory have developed a unique battery chemistry that promises to greatly extend battery life by making the electrolyte serve two functions. In a study, Pushing the Theoretical Limit of Li-CFx Batteries: A Tale of Bi-functional Electrolyte, which was published in the Journal of the American Chemical Society, ORNL… Read more »
