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 polyphosphazene polymer and a lithium salt dissolved or dispersed in the polymer, wherein the lithium salt occupies a weight fraction from 0.1% to 50% based on the total weight of the lithium salt and the polyphosphazene polymer combined; wherein the polyphosphazene polymer permeates into the anode and/or the cathode and in physical contact with the anode active material inside the anode and/or in physical contact with or chemically bonded to the cathode active material inside the cathode; and wherein the electrolyte further comprises from 0% to 50% by weight of a non-aqueous liquid solvent dispersed in the polymer, based on the total weight of the lithium salt, the polymer, and the non-aqueous liquid solvent combined.
