Claim 0:
1. A solid polymer electrolyte comprising:
a multifunctional acrylate-based polymer;
a C2 to C10 polyalkylene oxide;
a lithium salt; and
a non-aqueous solvent, which is present in a solid state at room temperature and is homogeneously mixed within the solid polymer electrolyte through a melting process, and wherein the non-aqueous solvent comprises dimethyl sulfone,
wherein the multifunctional acrylate-based polymer and the polyalkylene oxide form a semi-interpenetrating polymer network (semi-IPN), and
wherein the multifunctional acrylate-based polymer, the C2 to C10 polyalkylene oxide, the lithium salt and the non-aqueous solvent together are present in an amount of more than 70% by weight of solids, based on a total weight of the electrolyte.
