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:
- an array of solid-state thin-film batteries located on a surface of a substrate, wherein each solid-state thin-film battery of the array of solid-state thin-film batteries comprises a bottom electrode, a battery cell material stack and a top electrode;
- a fuse element in proximity to each solid-state thin-film battery of the plurality of solid-state thin-film batteries, wherein each fuse element has a first end connected to the bottom electrode of one of the solid-state thin-film batteries and a second end connected to a first bus bar, wherein the first bus bars are located on the substrate;
- and
- at least one second bus bar located above, and spaced apart from, each first bus bar, wherein the at least one second bus bar contacts a surface of the top electrode of each solid-state thin-film battery.
