Abstract
A method of producing an electrode slurry for use in battery manufacturing includes mixing a plurality of slurry components within an internal volume of a mixing container, transmitting ultrasonic signals across the internal volume of the mixing container, monitoring an attenuation of the ultrasonic signals over a period of time, determining when an end-of-mixing condition is met when the acoustic attenuation reaches a predetermined value, and stopping the mixing when the end-of-mixing condition is met.
