The sports car prototype and the battery charger (close-up above), which completely charges in 5 minutesNyobolt
Nyobolt, a company founded in 2019 at the Department of Chemistry of the University of Cambridge, UK, presented its ultrafast charging batteries in a prototype electric sports car in July. According to the company, the battery can be charged from 10% to 80% in 4 minutes and 37 seconds, twice the speed of most current electric vehicles with fast charging batteries. Nyobolt used materials that allow electrons to be transferred more quickly between the anode and cathode, as well as cells with low impedance (a circuit’s resistance to the passage of an electrical current), which generate less heat and make it easier to manage high power levels while charging. The product is based on research into supercapacitors, which complement batteries and allow a charge to be transferred to an electrode within minutes, carried out at the University of Cambridge by Clare Grey and Sai Shivareddy, the company’s cofounder and CEO (University of Cambridge, July 1; Science, April 18).
