Ultra-Thin Battery One-Half Millimeter Thick

Ultra-Thin Battery One-Half Millimeter Thick
Mar-23-15
By arranging electrodes alongside each other instead of stacked, engineers have created an ultra-thin battery that is practically two-dimensional.

The battery, created by a team from KAIST, is said to be the first to use this "coplanar interdigitated structure" for bulk applications (previous iterations in microbatteries had limited applications). The electrodes are about 400 µm apart, and are protected from short circuiting by a system of interelectrode barriers, which prevent direct electrode contact, and a "curvy electrode structure" that prevents contact when the battery bends. The battery also has a relatively high voltage even after 5000 bending cycles.

Possible applications for the battery include use in a smart card or wrinkle smoothing patch, or as a backup battery concealed in the band of a watch.
