Nyobolt raises £43.9m to scale ultra-fast charging battery technology

An estimated £43.9m has been secured by Nyobolt, a Cambridge-based developer of high-power lithium-ion batteries. The company produces integrated energy-storage systems that offer ultra-fast charging and long operational lifespans.

Founded in 2019, the business combines proprietary anode materials with advanced cell design and integrated power electronics. These technologies target mission-critical sectors including AI data centres, autonomous robotics, warehouse automation, electrified heavy-duty machinery, and electric vehicles.

This funding round contributes to a total of £44.3m raised by the firm throughout 2026. Previous filings show £25.3m was generated in 2025.

Nyobolt currently lists a headcount of 129 employees. Its solutions aim to reduce total cost of ownership for industrial users.

A patent portfolio supports the firm's global operations. Formal documentation for this specific share allotment was filed in April.
