The performance and the lifetime of energy storage devices can be hindered by the growth of metal dendrites during operation. Electrolytes having dendrite-inhibiting additives can result in significant improvement. In particular, energy storage devices having an electrode containing a metallic element, M1 can be characterized by a non-aqueous, liquid electrolyte having a first salt and a dendrite-inhibiting salt. The first salt can have a cation of M1 and the dendrite-inhibiting salt can have a cation of metallic element, M2, wherein the cation of M2 has an ionic size greater than, or equal to, the cation of M1.
