Abstract

This disclosure relates to ultrasonic devices and methods to use, manufacture and recondition new and degraded batteries. The disclosure may be used to manufacture or restore primary or secondary type batteries or as a preventive maintenance process for operational batteries. The disclosure utilizes an ultrasound transducer to provide ultrasound energy into a battery. It may be used to charge low or dead batteries, to clean fouled battery plates, to remix stratified electrolytic solutions and to dissolve and/or suspend solid particulates within a battery. Battery reconditioning may be accomplished through the action of the ultrasound waves directly or indirectly through the ultrasound waves producing cavitations and free radicals within the electrolyte 104. Sonication may be accomplished on a batch basis, on a controlled basis such as a timer or voltage signal, or cooperatively with the battery charging.
