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.
