1. A method comprising:
in a battery including a first electrode and a second electrode, applying a direct current (DC) bias to one of the first electrode and the second electrode; and
applying an alternating current (AC) electrical waveform to at least one of the first electrode or the second electrode of the battery comprising a plurality of layers, the AC electrical waveform inducing an electrodynamic effect in at least one layer of the battery.
