Flat Polymer Electrolytes Promise Thin-Film Power.

摘要

In laboratories all around the world, scientist and engineers are working on a new solid-state battery that could be fabricated much thinner than 100 micrometers. The battery uses a solid polymer electrolyte as the ionically conducting medium, instead of a liquid electrolyte. Flat cells have been available for several years and have been incorporated into devices such as the Polaroid instant-film pack. However, these have been modifications of conventional liquid-electrolyte cell designs. Recent innovations in solid-state batteries that use lithium anodes, solid cathodes, and a solid polymer electrolyte that both separates and provides the ionic pathway between the anode and cathode.
