QA/QC Technologies - High Resolution-High Throughput Ultrasound CALENDARING
Ultrasound has emerged as a promising non-destructive testing approach for battery inspection. Factors such as material properties, density, and porosity influence the interaction of ultrasonic waves with battery materials. In lithium-ion batteries, wave propagation can be described using theories like Biot's theory for fluid-saturated porous media or the slurry model for electrode coatings.
In-line, high voxel count imaging
Thickness & Density Measurement: Measures electrode thickness and uniformity to maintain consistent performance.
Software enabled metrology
Electrolyte Distribution Analysis: Evaluates the uniform distribution of the electrolyte, critical for battery efficiency.
Software enabled electrical test (SoC)
Quality Control: Ensures proper alignment of components and verifies manufacturing precision. Data Integration: Provides data for process optimization and feedback into manufacturing systems. Defects & Voids: Increases resistance, weakens structure → Reduce efficiency and long-term performance.
