Abstract: A rechargeable battery has 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 includes an anode active material selected from lithium, lithium titanium oxide, graphite, or silicon. A separator is positioned between the cathode and the anode. The separator is impregnated with an in-situ-formed and synchronously polymerized non-flammable quasi-solid-state electrolyte. The electrolyte is formed from a solution of monomer, lithium salt, and cross-linker. The solution wets the cathode active material and the anode active material such that the polymerized non-flammable quasi-solid-state electrolyte impregnates the cathode active material and the anode active material. The manufacturing procedures are compatible with production methods of Li-ion batteries, such as drop casting, impregnating, injecting, and printing.

Abstract: A meta-solid-state battery includes a first layer disposed on a first current collector, a second layer disposed on a second current collector, and third layer disposed between the first layer and the second layer. The first layer and the second layer are the cathode and anode electrodes. The third layer includes a first meta-solid-state electrolyte material. Each of the cathode and anode electrodes contain: an active material in an amount ranging from approximately 70% to 99.98% by weight, a carbon additive in an amount ranging from approximately 0.010% to 20% by weight, and a second meta-solid-state electrolyte material in an amount ranging from approximately 0.010% to 10% by weight. The first and second meta-solid-state electrolyte material include a gel polymer.
