US 2016/0104888 A1 · POROUS, THIN FILM ELECTRODES FOR LITHIUM-ION BATTERIES

Abstract

A porous thin film battery is described herein. The battery includes a substrate, a porous thin film cathode formed on the substrate, an electrolyte layer formed on the porous thin film cathode and a porous thin film anode formed on the electrolyte layer. The porous thin film cathode includes a first set of pores initially filled with a quantity of a first polymer material and then the first polymer material is removed to form the first set of pores. The porous thin film anode includes a second set of pores initially filled with a third polymer material and then the third polymer material is removed to form the second set of pores. A method of forming the porous thin film battery is also described. A system for forming the porous thin film battery is also described.
