The solvated metal particle-coating system includes a metal additive and a polar outer-sphere electron transferring solvent. The metal additive is solvated in the polar outer-sphere electron transferring solvent. The polar outer-sphere electron transferring solvent may include liquid ammonia, methylamine, and/or hexamethylphosphoramide. The metal additive may include an alkali metal and/or an alkaline earth metal. The solvated metal additive within the polar outer-sphere electron transferring solvent may be used to coat a metal particle and/or a metalloid particle as a layer. As the polar outer-sphere electron transferring solvent evaporates, the solvated metal additive is coupled to the metal particle and/or the metalloid particle.
