Nyobolt is a British battery technology company, spun out of research at the University of Cambridge, that develops high power battery systems using niobium tungsten oxide cells. Its technology has been used in warehouse robotics and is being developed for applications including physical AI, data centre power infrastructure and mobility.
History Nyobolt was established in 2019 by Professor Clare Grey and Dr. Sai Shivareddy, following research into niobium-based anode materials at the University of Cambridge.George Simister, The company initially focused on scaling its proprietary anode material and testing its integration into commercial cell manufacturing processes.David Manners,
Over the following years, Nyobolt expanded its capabilities in battery systems and power electronics, secured Series A, B and C funding rounds, and began pilot testing in high-power applications such as electric vehicles, Physical AI applications (humanoids, warehouse robotics), AI Data Centres and industrial automation.Sofia Chesnokova,Cate Lawrence,
In 2020, Nyobolt opened a cell and prototyping hub in Boston, United States.Mike Scialom, A year later, it established a materials research and development facility in Cambridge, United Kingdom. Three years later, the company unveiled an electric vehicle demonstrator capable of six-minute charging to demonstrate its technology.
By 2025, the company's commercial focus had expanded beyond electric-vehicle applications. Reporting by The Next Web described physical AI, warehouse robotics and data-centre power systems as emerging markets for its high-power batteries.
Funding In May 2026, Nyobolt raised $60 million in a Series C round at a valuation of $1 billion. The round was led by Symbotic, whose autonomous warehouse robots use Nyobolt batteries, with participation from IQ Capital, Latitude, Scania Invest and CBMM. The investment brought the company's total funding to approximately $160 million.
At the time of the funding round, The Next Web reported that Nyobolt's revenue was growing fivefold year-on-year, alongside increased demand from physical-AI and AI data-centre applications.
Battery technology model Nyobolt develops high-power lithium-ion batteries utilising both niobium-based and graphite-based anodes designed for ultrafast charging and long operational life.David Manners, The niobium-based technology grew out of research by Clare Grey and colleagues into a family of niobium tungsten oxides whose structure allows lithium ions to move rapidly through the anode material.
The company's technology integrates materials science with battery cell engineering, power electronics, and system-level controls.Matt De Prez, Its batteries have been developed for applications including electric vehicles, robotics, consumer electronics and industrial tools where rapid charging and repeated charge-discharge cycles are important operating requirements.
AI data centres Nyobolt has also developed the Dynamic Response System (DRS), a rack and sidecar level energy storage system designed for the Open Compute Project Open Rack V3 power infrastructure. According to the company, the system is intended to respond to short duration GPU power transients during AI workloads while also providing backup power.
The company's work on high power energy storage for data centres was discussed by Nyobolt co-founder Sai Shivareddy in a February 2026 episode of Compass Datacenters' Not Your Father's Data Center podcast. The discussion covered the use of fast-response battery systems to manage fluctuating AI workloads and high-density computing infrastructure.
Awards and recognitions In March 2025, Nyobolt won the annual Start Up Energy Transition (SET100) Award in the category Mobility & Transportation, held by German Energy Agency (dena).
In summer 2025, Nyobolt was selected as a winner of Hyundai Motor Europe's Open Innovation Challenge, organized in collaboration with HYUNDAI CRADLE and Plug and Play Tech Center.
In January 2026, Nyobolt was ranked 17th in the hardware category of The Sunday Times 100 Tech 2026, based on three-year annual sales growth of 102.54%.
In May 2026, Nyobolt was also ranked among the 50 most innovative companies in the robotics space by The Robot Report.
Customers and partnerships In September 2025, Nyobolt announced that its high-power, ultra-fast charging battery technology was being integrated into Symbotic's fleet of autonomous mobile robots (AMRs). The system provides greater energy capacity at a lower weight than the ultracapacitors previously used in the robots. Symbotic began limited production use in June 2025, with wider deployment announced for September 2025. The module was designed to be compatible with earlier robot models and existing charging infrastructure.
The relationship expanded in 2026 when Symbotic led Nyobolt's Series C financing round. Tech Funding News reported that Symbotic's SymBot robots were already using Nyobolt batteries at the time of the investment.
