Micro Batteries in Tomorrow’s Smartphones

In the era of connected devices, intelligent connected micro sensors require miniature embedded energy sources with great energy density. For ultra-thin—or planar—micro batteries, increased energy density means using thicker layers of materials, which has obvious limitations. A second method consists in machining a silicon wafer and producing an original 3D structure made of simple or double micro tubes. 3D batteries keep their 1mm2 footprint area, but develop a specific area of 50 mm2—an enhancement factor of 50! These robust micro tubes are large enough (of the order of the micron) to be coated with multiple layers of functional materials.
