QUASI-SOLID AND SOLID-STATE ELECTROLYTE FOR LITHIUM-ION AND LITHIUM METAL BATTERIES AND MANUFACTURING METHOD

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
