Introducing Tiny, an ultra-thin, high-capacity battery

The Tiny lithium-ion microbattery is redefining the international state of the art in miniature energy storage, with a thickness of less than 100 microns, a surface area of just a few square millimeters, and a capacity three times that of competing batteries. Leti and Liten developed Tiny, which is made using a thin-layer deposition technique. A solid electrolyte makes the battery safe, robust under high temperatures, and extremely long-lasting—Tiny’s lifespan is excellent, both during cycling and on the shelf.

The technology is currently being scaled up to ready it for manufacturing and is expected to hit the market in late 2021. The product will initially target medical applications and, specifically, implanted devices and integration into contact lenses.
