London-based battery tech start-up Sention Technologies has raised £3.7 million in a seed funding round to accelerate the commercialisation of its cutting-edge diagnostic tools for the battery industry.
The round, led by Twin Path Ventures, attracted backing from a strong line-up of energy and AI-focused investors, including Doral Energy-Tech Ventures, Endgame Capital, Energy Revolution Ventures, G.K. Goh Ventures, Green Angel Ventures, Third Sphere, and the UK Innovation and Science Seed Fund.
Founded with the aim of tackling battery inefficiencies and safety concerns, Sention has developed a proprietary ultrasonic scanning technology that allows users to “listen” inside batteries and produce 3D visualisations of their internal structure. When paired with advanced machine learning models, the platform can predict battery health, forecast degradation, and flag critical safety risks like thermal runaway.
The company says the new capital will be used to bring its Senturion benchtop ultrasound device and Sentinel, its AI-powered diagnostics software, to market. Funds will also support R&D on a third product — Sentry — designed for real-time diagnostics on live production lines.
Sention’s CEO, Professor Dan Brett, called the raise a “significant milestone” and said the company’s mission is to deliver real impact to a battery industry grappling with high failure rates, product recalls, and a lack of reliable, non-invasive testing tools.
“Batteries are transforming the way we live and leading us toward Net Zero, but they come with challenges,” Brett said. “This investment will enable us to deliver our products to customers, making a real difference in the battery industry.”
Twin Path Ventures said Sention’s approach — combining machine learning with electrochemical insights — has the potential to “transform the way batteries are developed, manufactured and used.”
With battery quality control under increasing scrutiny across the energy storage and electric vehicle markets, Sention’s platform promises to reduce scrap rates, improve performance, and enhance safety for battery manufacturers, developers and integrators.
The company has already seen strong early interest and will use the funding to expand its team and scale operations ahead of broader commercial rollout.
