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 »
