AI Technical Summary
Technical Problem
Conventional acoustic analysis methods for electrochemical devices and materials require contact and the use of couplants, which can cause measurement inaccuracies, damage, and hinder automation and scaling.
Method used
The use of an electromagnetic acoustic transducer (EMAT) configured for contactless acoustic analysis, eliminating the need for couplants and allowing for non-destructive, automated measurement of electrochemical devices and materials.
Benefits of technology
Contactless EMAT-based acoustic analysis enhances measurement reliability, safety, and throughput by reducing errors from inconsistent contact and couplant variations, and enables early-stage monitoring and quality control in electrochemical device production.

Abstract
Acoustic analysis systems and methods for electrochemical devices and materials An acoustic analysis system for an electrochemical device or electrochemical material is provided. The system comprises a housing configured to receive an electrochemical device or electrochemical material for acoustic analysis; and at least one electromagnetic acoustic transducer configured for contactless acoustic analysis of the electrochemical device or electrochemical material received by the housing. Preferably, the system further comprises a motion controller configured to enable translation and / or rotation of the at least one electromagnetic acoustic transducer relative to the electrochemical device or electrochemical material received by the housing. A method of acoustic analysis for an electrochemical device or electrochemical material is also provided, the method comprising performing acoustic analysis on an electrochemical device or electrochemical material using an electromagnetic acoustic transducer, wherein the electromagnetic acoustic transducer is configured for contactless acoustic analysis by generating Lorentz force which induces acoustic waves in the electrochemical device or electrochemical material.
