Description
This research investigates the use of acoustic measurements as an alternative means of non-destructive quality control for Li-ion battery films. The goal of this research is to enable accurate, non-destructive inspection of the battery electrode as it is being manufactured, so that problems can be identified and addressed early on. Here we report on our efforts to distinguish between films with different mechanical properties using acoustic resonances and surface acoustic wave (SAW) velocity. We were able to differentiate between films of various coating thicknesses using resonance measurements. We also used resonance measurements to monitor a material as it dried. SAW velocity measurements need further work for successful implementation.
