We report characterization of spray-based nanoporous particle synthesis for use in the cathode of lithium-ion batteries. Ultrasonic Microarray Spray Tuning (uMIST) was used to create microdroplets of salt solutions and battery material precursors, and the size distributions of produced microdroplets were investigated with a MicroOrifice Uniform Deposit Impactor (MOUDI). Experimental challenges associated with spray orientation, flow control and consistency of operation were addressed, and a promising solution for continuous droplet collection to obtain a statistically relevant droplet size distribution was proposed. Improved analysis capabilities will lead to a better understanding of the uMIST droplet formation mechanism.
