GRADED COMPOSITION ELECTRODE WITH ACTIVE COMPONENT MIX AND SOLID-STATE ELECTROLYTE

A lithium-ion battery includes multiple electrodes. At least one of the electrodes is comprised of multiple sheets of electrode mixture, and each of the sheets includes a different percentage of a solid-state electrolyte within the electrode mixture. The sheets are laminated together and to a current collector such that a bottom sheet nearest the current collector comprises a lowest percentage of the solid-state electrolyte. A gradient of percentages of the solid-state electrolyte is formed from the bottom sheet to a topmost sheet comprised of a highest percentage of the solid-state electrolyte.
