An electric car battery developed by UK start-up Nyobolt has successfully charged from 10% to 80% in four minutes and 37 seconds in a live demonstration.

It was achieved with a specially-built concept sports car on a test track in Bedford, and is part of industry-wide efforts to get electric vehicles charging more quickly. By comparison, an existing Tesla supercharger can charge a car battery to 80% in 15-20 minutes. Independent tests confirm Nyobolt batteries can last over 600,000 miles with minimal capacity loss, positioning Nyobolt as a leader in sustainable and efficient EV battery technology.

Founded in 2019, Cambridge-based Nyobolt utilizes next-generation patented carbon and metal oxide anode materials, innovative cell design, and integrated power electronics to create high-power battery systems. These batteries cater to various applications, including heavy-duty trucks, robotics, and consumer devices requiring quick recharge cycles.

Nyobolt’s technology addresses the degradation issues of typical lithium-ion batteries. Nyobolt’s cells complete over 4,000 full Depth of Discharge cycles while retaining significant capacity. Independent testing corroborates these findings, with cells achieving over 4,400 cycles and only a 50 percent rise in internal resistance, much lower than industry norms. Dr. Sai Shivareddy, Nyobolt’s co-founder and CEO, emphasizes that their low impedance cells offer extended battery life and sustainability, crucial for long-term EV adoption.

The Nyobolt EV prototype in which the battery was tested is a sports car weighing just 1,250kg, demonstrating that Nyobolt can enable lighter and better-handling EVs. This compact battery pack allows for energy-efficient vehicles that are cost-effective and resource-efficient. Shane Davies, Nyobolt’s director of vehicle battery systems, highlights that their technology supports creating excitement in the EV segment by reducing charging downtime and making electrification more accessible.

Nyobolt’s immediate goal is to showcase and test its battery technology, with low-volume production feasible within a year and plans for larger-scale manufacturing by 2025. The flexible manufacturing model allows for substantial production capacity. Additionally, Nyobolt’s EV architecture can be retrofitted to existing platforms, significantly reducing charge times and enhancing battery life. The innovative cooling system ensures minimal heat generation, even during fast charging or high-performance driving.

Nyobolt’s battery technology, developed by University of Cambridge scientists, leverages low impedance cells and advanced anode materials for ultra-fast charging without compromising battery life.

The company is already engaging with eight vehicle OEMs and plans to deploy its technology in robotics and heavy-duty commercial vehicles.
