Abstract:

Electroacoustic battery sonication rehabilitates a battery by decreasing metallic shorting across battery elements through sonication. Sonication may be produced by application of an electrical signal of selected frequency to the terminals of a battery, thereby establishing a resonant condition within the battery. Alternately, sonication may be provided by transducers placed within a battery and receiving a drive signal of selected frequency to establish a resonant condition within the battery. By removing metallic shorting, e. g. , lead hydrates in the case of a lead acid battery, undesirable electrical conduction between battery plates diminishes and battery charging efficiency and capacity increase.
