Nyobolt, a battery technology company from Cambridge, founded in 2019, has now raised $60 million at a $1 billion valuation to scale its technology.
Symbotic, a Nasdaq-listed AI robotics company whose SymBot robots already use Nyobolt’s batteries, led the Series C funding round. Other investors included IQ Capital, Latitude, Scania Invest, and CBMM. With this round, Nyobolt’s total funding is now about $160 million.
Nyobolt was co-founded by Dr Sai Shivareddy and Professor Clare Grey, a Royal Society fellow and top battery materials scientist at the University of Cambridge. Their technology uses specialised anode materials, advanced cell design, and built-in power electronics to enable ultrafast charging in seconds and deliver at least 10 times the lifespan of conventional lithium-ion batteries.
Nyobolt’s battery gives Symbotic’s warehouse robots six times more energy capacity than the ultracapacitors they used before. The battery is also 40% lighter and lets the robots work around the clock without needing to stop to charge or worry about battery wear, as per the company’s claim.
“Nyobolt is enabling the always-on, always-moving infrastructure that physical AI demands. The enterprises deploying autonomous systems at scale can’t afford downtime, swap time, or power flickers. Our technology delivers a powerful trifecta: improved performance, exceptional durability, and a more sustainable operation, enabling a new generation of machines to run harder and smarter,” says Shivareddy.
Nyobolt is already known for its role in robotics, but it is now making an impact in data centres. Large-scale AI workloads can cause sudden power surges that older backup power systems can’t handle. Nyobolt’s instant-power technology fills this need and creates a new market for the company.
The broader next-generation battery market is crowded. StoreDot, the Israeli fast-charging startup, focuses primarily on extreme fast charging for electric vehicles. Enovix and Amprius, the two most closely watched US players, are advancing silicon-anode approaches aimed at high energy density for consumer electronics, aerospace, and defence. Neither is pursuing the same combination of ultrafast charging, high cycle life, and robotics-specific integration that Nyobolt has built its commercial case around.
“Nyobolt’s proven technology is a key enabler of enhanced uptime and efficiency for our customers, and we’re excited about the overall market potential of a new instant power infrastructure across multiple applications,” adds Symbotic chief strategy officer Bill Boyd.
The company is also working with a major, unnamed humanoid robotics developer to help these robots work longer between charges, since they often struggle with limited power.
The $60 million investment will help Nyobolt grow its development projects, boost manufacturing, and build stronger business partnerships. The company is also moving into the Indian market. It has signed an agreement with the state of Rajasthan to provide more than 100MW of off-grid AI data centre and power management systems.
Nyobolt has about 115 employees and serves customers in the warehouse, humanoid robotics, and data centre sectors.
