Weighty Polymers Impact Battery Stability and Safety Materials prevent battery failure by inhibiting tree-like growths | Cornell Energy Systems Institute

Optical images of sodium deposited from an electrolyte as electrical current of 1 mA/cm2) (seeded with blue particles for visualizing the associated flow of electrolyte) show the growth of tree-like structures that short circuit batteries in a liquid electrolyte without polymer additions (A to D) and with polymer additions (4 weight%) (E to H) for 15-minute increments, with images D and H being after an hour. Without the polymer additions (A to D), the sodium deposits are mossy and rough. In contrast, the e
