Patent ID: 11949109

Abstract:
An electrode for a rechargeable lithium battery, the electrode comprising an electrode active material layer comprising an electrode active material that is in physical contact with or mixed with a quasi-solid or solid-state electrolyte, wherein the electrolyte comprises a polymer, which is a polymerization or crosslinking product of a reactive additive (reactive liquid electrolyte) comprising (i) a first liquid solvent that is polymerizable, (ii) an initiator and/or curing agent, (iii) a lithium salt, and (iv) an optional second liquid solvent; wherein the first liquid solvent occupies from 1% to 99% by weight and the second solvent, if present, occupies from 0.1% to 99% by weight based on the total weight of the reactive additive; wherein the first liquid solvent has a lower flash point, a higher vapor pressure, a higher dielectric constant, or a higher solubility of the lithium salt as compared with the second liquid solvent.
