INSPECTION OF BINDERS AND SLURRY MIXTURES FOR USE IN BATTERY FABRICATION BASED ON ACOUSTIC SIGNAL ANALYSIS
Systems, techniques, and computer-implemented processes for acoustic signal based improvements to one or more process steps in the manufacture of battery cells. Information gathered based on an acoustic signal based analysis in one process step can be used in one or more other process steps using any suitable combination of feedback and/or feedforward of the acoustic signal based analysis. Such feedback and/or feedforward can improve the overall quality of battery cells produced using the manufacturing process, efficiency/cost of the manufacturing process, improvement in yield/reduction in wastage of the battery cells produced using the manufacturing process and/or improvements in individual process steps.
1 . A method of manufacturing battery cells, the method comprising:
performing acoustic signal based analysis during a first process step for manufacturing one or more battery cells or components thereof; and
based on the acoustic signal based analysis performed during the first process step, determining one or more improvements to at least one of the first process step and a second process step for manufacturing the one or more battery cells or components thereof.
