Li-metal batteries often utilize liquid electrolytes that yield a solid–electrolyte interphase on electrodes; however, the role of anions in interphase formation remains unclear. Now it has been shown that anion-decomposition products provide varying contributions to interphase formation and that high-performance electrolytes balance effective interfacial passivation with minimized degradation.
