Improved battery systems, apparatuses, and methods for use in electric air, land, and marine vehicles and mobile, portable, and stationary electrical appliances and devices are provided. The systems employ acoustic and current manipulation of anode interface deposits including dendrites on or proximate lithium and other anodes. This invention may employ multistatic ultrasonic phased arrays and current modulation to 1) minimize deposit, e.g., dendrite, initiation and formation by acoustic stirring, 2) acoustically image dendritic growths to monitor changes in dendrite growths, 3) cue dendrite cleaning and battery shutdown to avoid short circuit, 4) induce failure in dendritic structure and shearing of at least a portion of the dendrite from the anode, and 5) transport sheared dendrites and other dead metal to a graveyard.
