"The electric current drives the flow of lithium ions through the solid electrolyte," Chiang explains. "That causes a highly concentrated flow of lithium ions at the dendrite tip. We believe that leads to a chemical reduction of the material compound, which leads to its decomposition into new phases. You start with a crystalline phase of the electrolyte, then there's a volume contraction after the deposition that is consistent with the embrittlement we see."
