AcouBatt
AcouBatt provides a passive acoustic-emission sensing system that lets battery manufacturers, researchers, and operators listen to internal cell activity in real time during formation, ageing, and operation. The system pairs external sensors with AI-powered signal classification and synchronizes acoustic data with existing electrochemical records to reveal events that voltage, current, and temperature measurements miss. It retrofits onto existing equipment with bespoke sensor fixtures tailored to specific cell formats and can run entirely on-premise for data control.

Problem
Battery formation and testing remain largely a black box, with manufacturers unable to observe internal cell activity in real time. Conventional monitoring relies on voltage, current, and temperature, which often only change after physical or chemical events inside the cell have already begun. This limits process optimization, delays anomaly detection, and contributes to scrap and safety risks.
Solution
AcouBatt provides a passive acoustic-emission sensing system that listens to cells during formation, ageing, and operation, capturing internal physical and chemical activity in real time. The system consists of external sensors, data-acquisition hardware, and AI-powered analysis software that classifies acoustic signals and synchronizes them with existing electrochemical data. This gives manufacturers and researchers a second, richer record of each cell, revealing variation and events that conventional measurements smooth over. The system is retrofitted onto existing equipment, with bespoke sensor fixtures tailored to each cell format and process, and can be deployed on-premise for full data control. In operation, acoustic monitoring adds an early-warning layer that detects abnormal degradation and at-risk cells before voltage or temperature move, complementing rather than replacing the battery-management system.
Target Audience
Primary customers are battery cell manufacturers, formation and quality teams, and R&D researchers working on lithium-ion, sodium-ion, silicon-anode, and solid-state cells across cylindrical, pouch, and prismatic formats. The system also serves BESS operators, integrators, and developers seeking earlier failure detection and health monitoring.
