Abstract
Described herein are borate salts useful as additives, binders, and electrolyte salts for solid state lithium ion batteries. In particular, the borate salts of Formula (I), Formula (II) and Formula (III) as described herein: can be polymerized, or can be bound to an existing polymer, to provide polymeric binders for ceramic solid state electrolytes that are themselves capable of ion transport independent of the ceramic.
Claims18
A single-ion conducting polymer-ceramic composite comprising particles of a lithium ion conducting ceramic in matrix of a single-ion conducting polymer;
- wherein the single-ion conducting polymer is formed by polymerization of a bis(2-allyl-2-fluoromalonato)borate salt in the presence of a cross-linking co-monomer comprising trimethylolpropane tris(3-mercaptopropionate) initiated by exposing the precursor mixture to ultraviolet light.
A single-ion conducting polymer-ceramic composite comprising particles of a lithium ion conducting ceramic in matrix of a single-ion conducting polymer;
- wherein the single-ion conducting polymer is formed by ultraviolet light initiated polymerization of lithium bis(2-allyl-2-fluoromalonato)borate in the presence of trimethylolpropane tris(3-mercaptopropionate) and 4-dimethylaminopyridine.
