Thinkclock Ltd Secures £25k to Advance Battery Health Analytics

Thinkclock Ltd, a company specialising in advanced battery prototyping and health analytics, has successfully raised £25k in a recent funding round. The investment, filed on 29 April 2026 with an allotment date on the same day, values the company at an estimated post-money valuation of £1.9m.

Based in Sunbury-On-Thames, with its headquarters in London, Thinkclock Ltd was incorporated on 28 October 2019. The company addresses critical challenges in battery performance and longevity by offering sophisticated solutions to a diverse clientele. Its services include battery prototyping powered by Digital Twins and in-depth battery health analytics utilising advanced spectroscopic techniques such as Electrochemical Impedance Spectroscopy (EIS), Acoustic Spectroscopy, and RF/mmWave Spectroscopy. Thinkclock Ltd also provides fully characterised recycled cells for second-life applications.

The company's offerings are designed for a broad market, including battery pack developers, cell OEMs, battery pack manufacturers, fleet operators, recyclers, system integrators, and financial partners. Thinkclock Ltd aims to provide diagnostic insights into battery health by relating microscopic data with observable system-level behaviour, leveraging models based on physics and machine learning.

Beyond its core services, Thinkclock Ltd is developing a Cell Benchmarking Database for commercially available cells, providing an independent source of truth for system integrators. Complementing this, the company has developed CellScope, a portable tool that quickly assesses cell health using spectroscopic techniques.

Regarding its operational scale, Thinkclock Ltd's latest accounts indicate a team of 2 employees. However, its LinkedIn profile suggests a larger team of 12 employees, reflecting potential growth or a broader network of contributors.

The £25k funding round, with a post-money valuation of £1.9m, positions Thinkclock Ltd as an early-stage venture in the burgeoning deep tech and clean energy sectors. This investment will likely support the company's ongoing research and development efforts in battery characterisation, modelling, and non-invasive sensing.

The UK's deep tech sector has shown significant resilience and growth, attracting substantial venture capital. In the first half of 2025, UK tech startups raised over $7 billion in venture capital investment, with deep tech and AI firms leading the way. Deep tech now accounts for 31% of all UK VC funding, a threefold increase over the last decade. This robust environment is further bolstered by government initiatives like the Faraday Battery Challenge and the new Battery Innovation Programme, which are investing hundreds of millions into battery research, development, and manufacturing to position the UK as a global leader in clean energy.

Specifically, the UK's electric vehicle (EV) battery sector has attracted record levels of VC investment, with UK-based EV battery startups raising $2.7 billion since 2018. The country ranks as the fourth largest recipient of EV battery VC investment globally since 2018, moving to third place in 2023 and 2024. The broader clean tech sector in the UK also saw a significant surge, securing £2.1 billion in climate-focused funding during the first half of 2025, a 34% increase from the previous year. Energy storage solutions, a key area for Thinkclock Ltd, are a significant component of this investment, with £588 million directed towards renewable energy infrastructure, including energy storage, in the first half of 2025.

Thinkclock Ltd's focus on battery health analytics and the use of machine learning aligns with the increasing integration of AI in deep tech, which accounted for 39% of all UK deep tech funding in 2025. This strategic alignment places Thinkclock Ltd within a dynamic and well-supported segment of the UK's innovation economy, poised to contribute to the nation's clean energy transition.
