Timeline for Nyobolt
Closed £44m Series C at $1bn valuation led by Symbotic, crossing the unicorn threshold
UK Startups and Innovation: Nyobolt hits £1bn on Symbotic-led Series C- How does Nyobolt charge a battery in five minutes?
- Nyobolt replaces the graphite anode in lithium-ion cells with a proprietary niobium oxide material, which allows lithium ions to insert and release much faster without structural degradation.Source: Nyobolt
- Who invested in Nyobolt's Series C?
- Nyobolt's £44m Series C was led by Symbotic with IQ Capital, Latitude, Scania Invest, and CBMM co-investing, valuing the company at $1bn.Source: Lowdown
- What does Nyobolt's battery technology compete with?
- Nyobolt's niobium anode cells sit between standard lithium-ion batteries (higher energy density, slower charge) and supercapacitors (instant charge, low energy density), offering fast charge with twenty times the energy storage of supercapacitors.Source: Nyobolt
- Which industries use Nyobolt batteries?
- Nyobolt's primary customers are industrial robotics (via Symbotic), with strategic investors suggesting interest in heavy commercial transport (Scania) and mining/materials (CBMM).Source: Lowdown
Background
Nyobolt crossed the unicorn threshold on 6 May 2026, closing a £44m Series C at a $1bn valuation led by Symbotic, the Nasdaq-listed AI warehouse robotics company, with IQ Capital, Latitude, Scania Invest, and CBMM also participating. Revenue grew five times year-on-year in the run-up to the round. The Cambridge University spinout, founded in 2019, has developed proprietary anode materials that enable 0-80% battery charge in under five minutes at twenty times the energy density of supercapacitors.
Nyobolt's core innovation is a niobium-based anode that replaces graphite in lithium-ion cells. Graphite anodes limit fast-charging because lithium ions insert slowly into the graphite structure; niobium oxide allows much faster intercalation without the structural damage that shortens battery life. The result is a cell chemistry suited to applications where ultra-fast charging matters more than maximum energy density: electric industrial equipment, robotics, power tools, and eventually electric vehicles in duty-cycle scenarios.
Symbotic's strategic lead investment is significant: Symbotic deploys Nyobolt's batteries in its AI-driven warehouse robots, creating a real-world performance reference. Scania Invest's participation signals interest from heavy transport; CBMM is the world's largest niobium producer and a natural strategic backer. Nyobolt becomes the UK's first battery-materials unicorn, a milestone for Cambridge's deep-tech ecosystem.
