The London-based startup has developed proprietary ultrasonic scanning technology that provides unparalleled insights into the internal structure of batteries. Their technology allows customers to ‘see inside’ batteries by listening to them and generating 3D images of the internal structure of cells. By combining this with advanced machine learning models, Sention predicts cell health, grades batteries, and forecasts degradation and critical issues like thermal runaway. These capabilities empower battery manufacturers, technology developers and fleet integrators to reduce waste, enhance performance and improve safety.

Sention CEO, Professor Dan Brett, says: "This funding marks a significant milestone for Sention as we continue to innovate at the forefront of battery diagnostics. The support of Twin Path Ventures, and our co-investors, validates our mission to enable the energy transition by transforming the efficiency and safety of batteries and other electrochemical technologies. Batteries are transforming the way we live and leading us toward Net Zero, but they come with challenges. This investment will enable us to deliver our products to customers, making a real difference in the battery industry.”

The continued development and adoption of battery technology require quality control and safety assurance advancements. The ability to inspect the internal structure and performance of batteries is key to achieving this; however, existing techniques are insufficient. Consequently, the industry is experiencing high battery production scrap rates (up to 30%), product recalls that run to billions, limited ability to grade cells and predict useful lifetime. 

With the funds, Sention will accelerate the commercialisation of its Senturion ultrasound instrument, a benchtop device offering real-time, non-invasive battery diagnostics, as well as its AI-driven data fusion software, Sentinel. The company will also invest in R&D for its next-generation product, Sentry, designed to integrate directly into production lines. Additional funding will support team expansion and customer acquisition, enabling Sention to serve a broader spectrum of battery manufacturers and energy innovators.

John Spindler of Twin Path Ventures says: “Sention has enormous potential to transform the way batteries are developed, manufactured, and used. Their technology uses the power of machine learning to predict how batteries perform, age and fail. As an AI specialist fund, we are excited by the tremendous potential that AI has to shape the battery industry.”

By delivering actionable data through its web-based platform, Sention supports critical decision-making across the supply chain, positioning itself as an essential partner for those developing and manufacturing batteries.
