Ultrasonic Acoustic Diagnostics for Aqueous Batteries
SUMMARY
This technology delivers enhanced aqueous battery diagnostics through ultrasonic acoustic signatures, enabling improved battery health assessment, manufacturing quality control, performance optimization, and longevity by monitoring critical internal parameters such as gas evolution, component density, state of charge, and electrolyte composition.
The Unmet Need: Accurate, real-time monitoring of aqueous battery internal states
Battery diagnostics are increasingly focused on in situ, non-invasive measurements that can capture multiple internal properties during operation and manufacturing. Existing approaches have limitations in tracking gas evolution, electrolyte variation, and the mechanical properties of internal components in real time. This can hinder performance optimization, failure prediction, manufacturing quality control, and assessment of battery health, state of charge, and local chemical conditions. Acoustic sensing and waveform analysis offer an opportunity to provide spatially resolved information about chemical and structural changes that conventional voltage or coulomb-counting methods may not reveal.
The technology interprets ultrasonic acoustic signatures to assess gas evolution, component density, elastic moduli, charge state, acid density, and local distributions of these properties. It is intended for lead-acid, metal-air, and other aqueous batteries. This approach differs from existing approaches by using battery-specific signal interpretation for simultaneous, noninvasive, in situ monitoring.
