Abstract
A rechargeable lithium battery comprising an anode, a cathode, and a quasi-solid or solid-state electrolyte in ionic communication with the anode and the cathode, wherein the electrolyte comprises: (a) a polymer, which is a polymerization or crosslinking product of a reactive additive, wherein the reactive additive comprises at least one reactive polymer, reactive oligomer, or reactive monomer and a crosslinking agent or initiator; (b) a lithium salt; and (c) from 0% to 30% by weight or by volume of a non-aqueous liquid solvent, based on the total weight or volume of the polymer, the lithium salt, and the liquid solvent combined. This liquid solvent proportion is preferably <20%, more preferably <10% and most preferably <5% by weight or by volume. The cathode comprises particles of a cathode active material and the electrolyte is in physical contact with at least a majority of or substantially all of the cathode active material particles.
