Abstract
Electrolyte additives for energy storage devices comprising compounds containing one, two, or more triple-bonded moieties are disclosed. The energy storage device comprises a first electrode and a second electrode, wherein 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. Compounds containing one, two, or more triple-bonded moieties may serve as additives to the electrolyte composition.
