Volkswagen AG is likely to decide in July whether to commit to an "all-electronic battery" developed by researchers at Stanford University that promises huge improvements in power density and cycle life, Bloomberg News reports.
Media reports say the solid-state technology could triple the range of today's electric vehicles, helping to make them directly competitive with piston-powered cars.
Researchers describe their system as a new class of electrical energy storage device that could lead to smaller, lighter, longer lasting, more powerful and virtually fireproof batteries. In 2010 the scientists created a San Jose, Calif.-based company, Quantumscape Corp., to commercialize the technology. VW acquired a 5% stake in Quantumscape last December.
The new technology stores energy through the movement of electrons rather than ions. It also uses a novel architecture that uses "electron/hole redox instead of capacitive polarization of a double layer."
VW Chairman Martin Winterkorn tells Bloomberg "progress is being made" on the new technology. The news service notes that Quantumscape has posted 11 job openings that include a head of battery manufacturing and an engineering manager to head a team to develop a new energy storage technology from concept through stable production.

Honda Re-Imagines and Re-Engineers the Ridgeline
When Honda announced the first-generation Ridgeline in 2005, it opened the press release describing the vehicle: “The Honda Ridgeline re-defines what a truck can be with its true half-ton bed payload capability, an interior similar to a full-size truck and the exterior length of a compact truck.” And all that said, people simply couldn’t get over the way there is a diagonal piece, a sail-shaped buttress, between the cab and the box.

Chevy Develops eCOPO Camaro: The Fast and the Electric
The notion that electric vehicles were the sort of thing that well-meaning professors who wear tweed jackets with elbow patches drove in order to help save the environment was pretty much annihilated when Tesla added the Ludicrous+ mode to the Model S which propelled the vehicle from 0 to 60 mph in less than 3 seconds.
