Abstract
Solid-state battery structures, particularly solid-state lithium-based battery structures, which are fast charging and have a high capacity are provided. Notably, fast charging, high capacity solid-state battery structures are provided that include a plurality of solid-state-thin-film batteries that are stacked one atop the other, or that include an array of interconnected solid-state thin-film batteries, or that contain a solid-state thin-film battery located on physically exposed surfaces of fin structures.
Claims12
A solid-state battery structure comprising:
- a plurality of substrate layers and dielectric material layers stacked one atop the other, wherein each dielectric material layer includes a solid-state thin-film battery located therein, wherein each solid-state thin-film battery comprises at least a bottom electrode, a cathode, a solid-state electrolyte, and a top electrode;
- a first via-filled contact structure interconnecting each bottom electrode together;
- and
- a second via-filled contact structure interconnecting each top electrode together.
