Additives for energy storage devices comprising phosphorus-containing compounds are disclosed. The energy storage device comprises a first electrode and a second electrode, where at least one of the first electrode and the second electrode is a Si-based electrode, a separator between the first electrode and the second electrode, and an electrolyte composition. Phosphorus-containing compounds may serve as additives to the first electrode, the second electrode and/or the electrolyte, as well as the separator.
