Battery diagnostics firm AcouBatt raises £1.1m led by Creator Fund with Ada Ventures
This article covers AcouBatt, a London-based greentech startup that has raised £1.1m in a pre-seed funding round to commercialise acoustic sensing and AI for battery manufacturing quality and safety. The funding will be used to expand engineering capacity, improve machine-learning models and advance pilots with battery manufacturers, supporting efforts to reduce scrap, speed formation and enhance safety as domestic battery production scales across the UK and Europe.
AcouBatt has raised £1.1m in a pre-seed funding round to commercialise acoustic sensing and AI for battery manufacturing quality and safety. The London-based greentech startup, spun out of University College London, says the cash will be used to expand engineering capacity, improve its machine-learning models and advance pilots with manufacturers as domestic battery production scales across Europe.
Why it matters
Battery production is a bottleneck for the electric vehicle and energy storage transition. Governments and industry are investing to build domestic capacity, but manufacturers face a familiar tension: scale up quickly while avoiding quality lapses that can create safety risks, production delays and material waste. Diagnostics that surface what is happening inside cells during formation could reduce scrap, speed throughput and improve safety — outcomes that matter to suppliers, OEMs and policymakers pushing to lessen reliance on overseas manufacturing.
Inside the product
AcouBatt builds acoustic emission sensors that listen for electrochemical and mechanical activity inside cells during manufacture. Those signals are fed to AI models that the company says can distinguish meaningful events from background noise and indicate when key formation processes have completed.
The company says the system can shorten formation times by up to 30% by identifying precisely when a cell has stabilised, and that it can detect early signs of defects that would otherwise remain hidden until later testing or field use. AcouBatt is positioning the technology for factory floors but also for battery energy storage installations and, potentially, electric vehicles, where early detection of underperforming or failing cells could avoid safety incidents or operational disruption.
Sensors and models are currently being trialled at the UK Battery Industrialisation Centre, where AcouBatt is benchmarking performance ahead of a planned commercial rollout next year. The underlying research was developed at UCL’s Electrochemical Innovation Lab as part of the Faraday Institution-backed SafeBatt project.
Who are the investors?
The round was led by Creator Fund, with participation from Ada Ventures. UCL Ventures supported the company’s creation and commercialisation work.
Creator Fund led the pre-seed cheque, citing the need for better factory-level visibility as battery demand grows faster than manufacturers’ ability to maintain quality at scale. Ada Ventures participated to back a diagnostics approach that could cut waste during the lengthy formation stage. UCL Ventures acted as a university commercialisation partner, helping translate lab research into a product being tested at UKBIC.
The new capital is earmarked for hiring engineers, advancing AI models and scaling pilot projects with battery manufacturers.

Founder perspective
AcouBatt was founded in 2025 by Dr Arthur Fordham and Chris Haoxin Xu after they met on London Business School’s Innovation to Market programme. The company’s approach builds on Dr Fordham’s research at UCL.
In the announcement, Dr Arthur Fordham, co-founder and chief executive of AcouBatt, said:
Batteries are the foundation of modern infrastructure, yet up until now, they have been tightly locked in a black box. That is why advanced diagnostics are the next major frontier. AcouBatt provides a diagnostic tool that not only saves massive amounts of time on the factory floor but helps manufacturers and operators truly understand and look after their battery systems from the moment they are formed to the end of their working life.
In the announcement, Chris Haoxin Xu, commercial director and co-founder of AcouBatt, said:
Western battery manufacturers are under immense pressure to scale and innovate at speed, while keeping safety and cost top of mind. Our technology opens the door for manufacturers to drastically cut waste, optimise their processes, and bring safer, better batteries to the market more quickly.
The bigger picture
AcouBatt’s funding and pilots sit at the intersection of two trends: a push to localise battery supply chains in the UK and Europe, and growing investor interest in tools that improve manufacturing yield and safety rather than only cell chemistry. The deal reflects growing interest from greentech investors in hardware diagnostics and production technologies that can be deployed across factories and storage sites.
As manufacturers and policymakers aim to scale production capacity, diagnostics startups such as AcouBatt will be watched closely. Trials at facilities like UKBIC and links to Faraday Institution research illustrate a pathway from university lab to industrial application that the UK wants to cultivate if it is to compete in the wider European battery ecosystem.
