Nyobolt, a UK-based pioneer in ultrafast-charging lithium-ion batteries using proprietary niobium tungsten oxide anodes, has raised $60M in Series C funding led by Symbotic. The round achieves a $1B valuation and includes IQ Capital, Latitude, Scania Invest, and CBMM. Proceeds will scale production of battery cells, packs, and integrated systems for AI data centers, robotics, and autonomous vehicles.
AI Power Crunch Fuels Battery Bets
The raise aligns with surging demand for high-power energy storage amid AI infrastructure growth. Nyobolt's batteries deliver millisecond response times and 80% charge in under 5 minutes, targeting power spikes in GPU racks and robot fleets. StoreDot has raised over $226M for silicon-dominant fast-charging EV batteries, while Sila Nanotechnologies secured $1.3B focusing on energy density. Nyobolt differentiates through 20x power density versus supercapacitors for mission-critical applications.
Data Centers Face Transient Power Gaps
AI data centers experience kilowatt-level microsecond spikes from GPU workloads, straining grids and legacy UPS systems. Robotics and autonomous machines demand always-on power without downtime from battery swaps or slow charging. Current lithium-ion batteries fall short on cycle life and response speed for these dynamic loads, per industry analyses.
Niobium Anodes Unlock Instant Response
Nyobolt's Dynamic Response System integrates cells with BMS, power electronics, and chargers using niobium-graphite anodes for controlled lithium transport. This enables 4,000+ cycles at 100% depth of discharge and instant power delivery under 1ms. Unlike energy-focused rivals, Nyobolt prioritizes power density for AI and robotics.
As Nyobolt CEO Sai Shivareddy noted:
"Nyobolt is enabling the always-on, always-moving infrastructure that physical AI demands."
Symbotic's batteries now offer 6x energy capacity, 40% less weight, and 10x cycle life versus ultracapacitors in SymBot robots.
Strategics Validate Robotics Traction
Symbotic, a leader in AI warehouse automation, led the round as Nyobolt powers its SymBots following a September 2025 partnership. IQ Capital brings deep tech expertise with prior battery investments like Molyon. Scania Invest eyes heavy-duty applications, while CBMM supplies niobium materials. The mix signals customer pull and material scale-up.
Fast-Charging Market Scales to $133B
The fast-charging lithium-ion battery market stands at $55.23B in 2025, projected to reach $132.67B by 2032 at 13.5% CAGR, driven by AI and EV adoption. EV battery packs alone hit $179B TAM with 8.1% growth to 2031. Competitors like Morrow Batteries raised $134M for sustainable cells, but Nyobolt targets high-power niches.
Cambridge Spinout Hits Unicorn
Nyobolt spun out from University of Cambridge research by Prof. Clare Grey, a leading battery scientist, and serial entrepreneur CEO Sai Shivareddy. The team holds ISO 9001:2015 certification and serves existing customers across UK, US, Germany, and Japan offices. Recent awards include #17 on The Sunday Times 100 Tech 2026 and Sustainability Champion.
India Expansion Powers AI Hubs
Nyobolt signed an MoU with Rajasthan, India, for 100MW off-grid AI data centers. Hiring accelerates with roles in Cambridge for people operations and Boston for cell engineering. Revenues grew 5x year-over-year ahead of commercial scale-up.
