Abstract: An amorphous composite solid electrolyte is provided that includes one or more three-dimensional branched macromolecules with a core portion and at least three arm portions connected to the core portion. Each arm portion includes a random copolymer or a block polymer comprising a first monomer and a second monomer with a molar ratio of the first monomer to the second monomer in the range from greater than 0 to less than or equal to 1. An ion conductive electrolytic solution including at least one lithium salt solution in an amount of approximately 1 mol/l to 10 mol/l is entrained within the branched macromolecule, with a weight ratio of the branched macromolecule to the ion conducive electrolytic solution equal to or lower than 1:9, such that the branched macromolecule has a swelling degree of at least 5:1 (liquid:polymer in weight) of the ion conductive electrolytic solution.

Abstract: The present invention provides a rechargeable lithium-ion battery with an in situ thermally-curable electrolyte. The thermally-curable electrolyte is cured from the thermally-curable electrolyte precursor solution including a first crosslinking agent, a second crosslinking agent, an initiator, an electrolyte solvent, an electrolyte salt, one or more electrolyte additives, and one or more monomers or a monomer polymerization product. The viscosity of the thermally-curable electrolyte precursor solution is below 200 cps such that the thermally-curable electrolyte precursor solution is infiltrated within the separator and the pores inside the cathode and anode layers then cured to form porous separator and porous electrodes fully permeated with a solid electrolyte.
