Abstract
Electrodes, electrolytes and/or separators for energy storage devices comprising functional boron-containing chemicals 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. Functional boron-containing chemicals may serve as additives to one or more of the electrodes, electrolyte and/or separator.
