Nyobolt hits £1bn on Symbotic-led Series C
UK Startups and Innovation- What is CBMM and why does it matter for batteries?
- CBMM is the world's dominant niobium producer, controlling 80-85% of global supply. Niobium enhances battery anodes for fast-charging cells — making CBMM a strategic investor in Nyobolt's ultra-fast battery technology.Source: Lowdown uk-startups-and-innovation U#4
- Why is Brazil's CBMM investing in a UK battery startup?
- CBMM invested in Nyobolt's Series C because Nyobolt's ultra-fast battery chemistry uses niobium-enhanced anodes, directly growing demand for CBMM's core product.Source: Lowdown uk-startups-and-innovation U#4
- What is niobium used for?
- Niobium is used in high-strength steel alloys, superconductors, and increasingly in battery anodes for fast-charging lithium-ion cells — the application Nyobolt is commercialising.Source: CBMM
Background
CBMM (Companhia Brasileira de Metalurgia e Mineração) participated in Nyobolt's Series C in May 2026, joining lead Symbotic and co-investors IQ Capital, Scania Invest, Latitude, and Walmart (via Symbotic's anchor customer relationship). Nyobolt's ultra-fast battery technology is built on niobium-enhanced anode chemistry; CBMM's investment is directly strategic as the world's leading niobium producer, giving it both a financial stake in demand growth and a commercial relationship with a high-profile application customer.
CBMM is a Brazilian mining and metallurgy company headquartered in Araxá, Minas Gerais, controlling approximately 80-85% of global niobium production. Niobium is a specialty metal used in high-strength steel alloys, superconductors, and increasingly in battery anodes for fast-charging lithium-ion and sodium-ion cells. CBMM has invested in battery technology companies globally as part of a strategy to develop and validate new demand sources for niobium beyond its traditional steel industry customers.
