How NanoGraf is commercializing the “world’s most energy-dense” 18650 battery cell with stable silicon oxide

Q&A with NanoGraf COO Connor Hund Graphite, a pure form of carbon, is a critical material for battery anodes. Graphite’s physical structure allows it to store lithium ions, which merrily migrate to the anode when the battery is charged. Unlike cathodes, which can be composed of various combinations of chemicals (cobalt, nickel, manganese, lithium, iron,… Read more »

JB Straubel talks Tesla, Redwood and the massive challenge of building an EV supply chain in new video

When I was a kid, everyone had a favorite Beatle (mine was George). Now I have a favorite Tesla co-founder: JB Straubel. He’s a visionary who converted a Porsche to electric drive and built a solar-powered racer, long before EVs were cool. He’s the engineering genius who personally went through and redesigned almost every component… Read more »
