Abstract
Electrolytes and electrolyte additives for energy storage devices comprising linear carbonate compounds.
Claims6
An energy storage device comprising:
- a first electrode and a second electrode, wherein at least one of the first electrode and the second electrode is a Si-based electrode and where the silicon is present as silicon particles;
- a separator between the first electrode and the second electrode;
- an electrolyte;
- and
- at least one electrolyte additive comprising a compound selected from Formulae (A), (B), and (C):
- wherein:
- each R1 and R2 is independently selected from the group consisting of
- and absent thereby leaving a negative charge;
- and
- R is a C1-C3 alkyl;
- wherein:
- each R1 and R2 is independently selected from the group consisting of
- and absent thereby leaving a negative charge;
- and
- R is a C1-C3 alkyl;
- and
- wherein:
- each R1 and R2 is independently selected from the group consisting of
- and absent thereby leaving a negative charge;
- R is a C1-C3 alkyl;
- and
- X is selected from the group consisting of an alkylene optionally substituted by
- or a chloroalkyl, a cycloalkylene, and a heteroalkylene with at least one —O—.
