Nyobolt raises £40.2m to scale ultra-fast charging battery systems

High-power lithium-ion batteries capable of ultra-fast charging are the core focus of Nyobolt Limited, which has secured an estimated £40.2m in its latest funding round. This investment brings the Cambridge-based company to an estimated post-money valuation of £50.9m.

Founded in 2019, Nyobolt develops integrated energy systems designed for applications requiring rapid charging and long operational lifespans. Its technology targets sectors including electric vehicles, robotics, industrial tools, and AI data centers. The company uses proprietary anode materials and advanced cell designs to provide high power density and extended lifecycles for heavy-duty applications.

The latest financial filings show Nyobolt generated £19k in revenue and reported a loss of £23.1m. The company currently employs between 116 and 122 people across its operations. This new capital follows a series of smaller funding injections throughout 2025, including a £13m round in March, £5m and £2.6m rounds in April, and a £1.7m round in December. Previous significant funding includes a £17m round closed in late 2022.

Nyobolt operates from its headquarters in Cambridge and maintains a global footprint to support its patent portfolio. The company's solutions aim to reduce the total cost of ownership for power-demanding industries by providing mission-critical uptime through its instant power technology. Documentation for this latest allotment was filed in April 2026.
