1. An acoustic device that is configured to be operably coupled to and used with a battery, the acoustic device comprising:
an acoustic wave generator, wherein the acoustic wave generator comprises a piezoelectric substrate and a transducer, wherein the transducer comprises (i) one or more pairs of metallic interdigital transducers, (ii) a layer of conductive material, or (iii) one or more contact pins, wherein the acoustic wave generator generates acoustic waves during operation of the battery and streams the acoustic waves into the battery to cause uniform distribution of an electrolyte in the battery to prevent or reduce dendrite formation in the battery.
