With Tesla’s $5.5 billion “gigafactory” already producing cells for its line of cars and its “Powerwall” home energy storage systems, it now seems like a tenuous, toe-dipping approach with Volkswagen announcing its own battery plans.  VW may invest up to $15.5 billion according to Tech News, the outlet projecting the highest number.  Others with less money but promising technologies are also betting on better batteries. Tesla Gigafactory Grand Opening – More to Come With only 14 percent of its total area completed, the Tesla Gigafactory on Electric Avenue (what else?) near Sparks, Nevada, is already up and running, producing Tesla’s Powerwall and Powerpack battery systems.  According to Teslarati.com, “Elon Musk told investors at the 4th quarter earnings call earlier this …

All-Electron Battery – Stanford Strikes Again

With recent news of a solid-state battery coming for the labs of Yi Cui, a second solid-state solution seems to follow from another Stanford Laboratory.  The All-Electron Battery, funded at least partly by an ARPA-E grant that underwrote the program from 2010 to 2012, has fostered a startup, QuantumScape. Starting from the stated need for a battery “with twice the energy storage of today’s state-of-the-art Li-Ion battery at 30% of the cost,” ARPA-E worked with the premise that Stanford was “developing an all-electron battery that would create a completely new class of energy storage devices for EVs. Stanford’s all-electron battery stores energy by moving electrons rather than ions. Electrons are lighter and faster than the ion charge carriers in conventional …

Will VW Take on Tesla?

Volkswagen just bought a five-percent stake in a startup company called QuantumScape, a commercial spinoff of work done at Stanford University’s Nanoscale Prototyping Laboratory for Energy Conversion and Storage.  The Labroratory’s head, Fritz B. Prinz, Finmeccanica Professor of Engineering and Robert Bosch Chairman of Mechanical Engineering, explains: “Our team creates, models, and prototypes nanoscale structures to understand the physics of electrical energy conversion and storage. We are exploring the relation between size, composition, and the kinetics of charge transfer. We are also interested in learning from nature, in particular by studying the electron transport chain in plant cells.” (Note that the QuantumScape web site is curiously without detail, showing only four pretty pictures and making three or four non-controversial statements. …
