Details are not abundant yet, but according to Bloomberg, VW of America bought a five-percent stake in QuantumScape (and has an option to raise its holding). The tech could "more than triple" the EV range of VW, Porsche and Audi plug-in vehicles as soon as the middle of 2015, according to unnamed sources that Bloomberg talked to.
Former Stanford University researchers started QuantumScape in 2010. The bare-bones QuantumScape website (there's nothing there other than some contact information) doesn't offer many hints about what's happening at the company, but GigaOM's Katie Fehrenbacher notes that QuantumScape is licensing tech from the "All Electron Battery" project at Stanford a few years ago. It certainly sounds amazing:
If that's what's coming in a future e-Golf or E-Tron, sign us up.
[It's] a completely new class of electrical energy storage devices for electric vehicles that has the potential to provide ultra-high energy and power densities, while enabling extremely high cycle life. The All-Electron Battery stores energy by moving electrons, rather than ions, and uses electron/hole redox instead of capacitive polarization of a double-layer. ... If successful, this project will develop a completely new paradigm in energy storage for electrified vehicles that could revolutionize the electric vehicle industry.
