1. A rechargeable battery comprising:
a cathode including a cathode active material selected from lithium iron phosphate, lithium cobalt oxide, lithium manganese oxide, lithium nickel cobalt aluminum oxide, or lithium nickel manganese cobalt oxide;
an anode including an anode active material selected from lithium, lithium titanium oxide, graphite, or silicon;
a separator positioned between the cathode and the anode, the separator being impregnated with an elastic in situ and synchronously polymerized non-flammable quasi-solid-state electrolyte formed from a solution of monomer, lithium salt, and cross-linker, the solution wetting the cathode active material and the anode active material such that the formed non-flammable quasi-solid-state electrolyte impregnates the cathode active material and the anode active material;
wherein the monomers are selected from butyl acrylate, propyl acrylate, ethyl acrylate, methyl acrylate, butyl methacrylate, propyl methacrylate, ethyl methacrylate, methyl methacrylate, methoxy poly (ethylene glycol) methacrylate, vinyl acetate, ethyl cyanoacrylate, or methyl cyanoacrylate.
