Abstract
A bicyclophosphate-modified ionic liquid compound, the synthesis thereof, an electrochemical electrolyte containing a bicyclophosphate-modified ionic liquid compound, and energy storage device containing the electrolyte are disclosed.
Claims31
An electrical energy storage device electrolyte comprising:
- a) an aprotic organic solvent system;
- b) a metal salt;
- and
- c) an ionic liquid compound comprising:
- an anion (A−);
- and
- a cation attached to a bicyclophosphate moiety according to the formula:
- wherein:
- CAT+ is a pyrrolidinium, piperdinium, azepanium, sulfonium, phosphonium, pyridine, imidazolium or a 5- or 6-membered heterocyclic ring having 1 to 3 heteroatoms as ring members including nitrogen, oxygen, silicon or sulfur;
- and
- L is (a) a linker, including a C1-C8 alkyl, alkenyl, alkynyl, alkoxy, ester, carbonyl, phenyl, thioether, sulfoxide, azo or aryl group, wherein any of the carbon or hydrogen atoms therein are optionally further substituted with a halide;
- (b) O, S, NH, or C;
- or (c) O, S, NH, or C attached to the linker, with the proviso that when L is an ester group then CAT+ is not an imidazolium.
