Developed by Nyobolt, a spin-off company from the University of Cambridge, the prototype of an electric sports car equipped with new batteries has achieved charging speeds twice as fast as vehicles on the roads today. These high-performing batteries do not suffer from degradation issues associated with lithium-ion batteries.
Nyobolt’s proprietary carbon and metal oxide anode materials, low-impedance cell design, integrated power electronics, and software controls have enabled the creation of high-energy-density batteries and charging systems that support various applications such as heavy-duty off-road trucks, electric vehicles, robotics, and consumer devices that require high power and fast recharge cycles.
The initial testing of the Nyobolt EV prototype using 350kW (800V) DC fast chargers confirmed its impressive charging capabilities. The battery can be charged from 10% to 80% in just four minutes and 37 seconds, allowing the prototype to achieve a range of 250 kilometers. Independent testing has shown that Nyobolt’s durable batteries can withstand over 4,000 rapid charge cycles or 965,000 kilometers with over 80% battery capacity retention.
Nyobolt’s compact size of the battery pack enables energy-efficient electric vehicles that are cheaper to buy and operate while also using fewer resources to manufacture. The company plans to start low-volume production of its battery assembly within a year and ramp up to 1,000 packs by 2025. Their flexible manufacturing model allows for volumes of up to two million cells per year.
Nyobolt’s technology is based on a decade of battery research conducted by scientists Clare Grey and Sai Shivareddy who invented cutting-edge supercapacitors. Key to their ability to deliver ultra-fast charging without compromising battery life are their low-impedance cells that generate less heat facilitating the management of high power levels during charging.
Nyobolt is currently in discussions with eight other vehicle manufacturers to adopt its technology for automotive applications while also utilizing its fast charging technology in robotics for improved performance in demanding environments where speed is essential.
