Abstract
Electrolytes and electrolyte additives for energy storage devices comprising a sulfonate ester compound 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, an electrolyte, and at least one electrolyte additive selected from a sulfonate ester compound.
Claims6
A method of forming an energy storage device, the method comprising:
- forming an energy storage device comprising a first electrode, an electrolyte, and a second electrode, wherein said electrolyte is formed by adding one or more sulfonate ester compounds as an electrolyte additive;
- wherein the sulfonate ester compound is of formula (I):
- where R1 and R2 are the same or different and are selected from the group consisting of H, alkyl, fluoro-alkyl, alkylene, alkoxy, alkenyl, alkenylene, alkynyl, alkynylene, cycloalkyl, cycloalkylene, aryl, arylene, heteroaryl, heteroalkyl, heteroalkylene and heterocycloalkylene, which may be optionally substituted.
