Abstract:
A dendrite resistant battery may include a first electrode, a second electrode, and an electrolyte interposed between the first electrode and the second electrode. The dendrite resistant battery may further include at least one acoustic wave device configured to generate a plurality of acoustic waves during a charging of the battery. The charging of the battery may trigger cations from the first electrode to travel through the electrolyte and deposit on the second electrode. The plurality of acoustic waves may agitate the electrolyte to at least homogenize a distribution of cations in the electrolyte. The homogenization of the distribution of cations may prevent a formation of dendrites on the second electrode by at least increasing a uniformity of the deposit of cations on the second electrode. Related methods and systems for battery management are also provided.
