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.

Inspection of binders and slurry mixtures for use in battery fabrication based on acoustic signal analysis

Systems, techniques, and computer-implemented processes are provided for acoustic signal based analysis of thin-films, electrode coatings, and other components of batteries. Data analytics on signals obtained by ultrasound excitation of materials is used to analyze electrode coating parameters, analyzing separators, and other battery components. Using the disclosed techniques in battery manufacturing and production can lead to reduction in wastage of damaged/scrapped battery cells and shorten production time.

Acoustic signal based analysis of films

A rechargeable battery cell a casing and first and second electrode materials separately positioned in the casing. A mechanical impulse element is positioned to mechanically move and dislodge gas bubbles from at least one of the first and second electrode materials in response to activation. In some embodiments the mechanical impulse element can include a vibratory piezoelectric element. In other embodiments, a gas vent in the battery cell can be used to release dislodged gas bubbles.
