Apparatuses and methods for acoustic and current manipulation of anode interface deposits in lithium anode batteries and other battery systems

A method of operating a battery comprising:

• providing a battery including a cell containing an electrolyte,
• a cathode positioned in the cell with an electrical connection to outside the cell,
• an anode positioned in the cell with an electrical connection to outside the cell and separated from the cathode by the electrolyte;
• providing at least one electronically steered ultrasonic array (ESUA) to provide acoustic energy inside the cell;
• and
• controlling, via a processor, the at least one ESUA to produce at least one pressure trap to transport at least one failed dendrite away from the anode.

A method of operating a battery comprising:

• providing a battery including a cell containing an electrolyte,
• a cathode positioned in the cell with an electrical connection to outside the cell,
• an anode positioned in the cell with an electrical connection to outside the cell and separated from the cathode by the electrolyte;
• connecting electrically at least one current source between the cathode and anode;
• and
• controlling, via a processor, the at least one current source to modulate the current relative to a charging current for the battery to weaken at least one dendrite growing on the anode to promote dendrite failure without melting the dendrite.
