Abstract

The electrolyte includes one or more salts and a silane. The silane has a silicon linked to one or more first substituents that each include a poly(alkylene oxide) moiety or a cyclic carbonate moiety. The silane can be linked to four of the first substituents. Alternately, the silane can be linked to the one or more first substituents and one or more second substituents that each exclude both a poly(alkylene oxide) moiety and a cyclic carbonate moiety.

Claims (21)

1. An electrochemical device comprising:

an electrolyte including one or more salts and a silane, the silane having a silicon linked to one or more substituents that include a poly(alkylene oxide) moiety, and wherein at least one of the one or more substituents includes a spacer positioned between the poly(alkylene oxide) moiety and the silicon, wherein the silane is represented by:
