Nyobolt

Nyobolt is a Cambridge-based battery-technology company building ultra-fast-charging, high-power energy systems for industries where uptime is non-negotiable. Founded in 2019 as a spin-out from the University of Cambridge's Yusuf Hamied Department of Chemistry, the company combines proprietary niobium-based anode materials, advanced cell design and integrated power electronics to deliver batteries that recharge in minutes and survive thousands of high-power cycles without significant degradation.

Its cells are designed for applications that cycle dozens or hundreds of times a day: autonomous warehouse robots, humanoid robots, industrial automation and AI data-centre infrastructure. Nyobolt's batteries are already deployed in Symbotic's SymBot autonomous mobile robots, where the company says they deliver six times the energy capacity of the ultracapacitors previously used, are 40% lighter, and offer at least ten times the cycle life of traditional lithium-ion technology.

The company is co-founded by CEO Dr Sai Shivareddy and Professor Dame Clare Grey FRS, the Cambridge electrochemist whose research underpins the technology. Nyobolt employs around 115 people across the UK, US and Asia, and in May 2026 reached unicorn status after a $60M Series C led by Symbotic at a $1B valuation, on revenues that grew fivefold year-on-year. Earlier rounds have been backed by IQ Capital, Latitude, Scania Invest, CBMM and H.C. Starck Tungsten Powders.
