3D APPROACH ON BATTERY AND SUPERCAPACITOR FABRICATION BY INITIATION CHEMICAL VAPOR DEPOSITION TECHNIQUES

摘要

Methods and apparatus for forming energy storage devices are provided. In one embodiment a method of producing an energy storage device is provided. The method comprises positioning an anodic current collector into a processing region, depositing one or more three-dimensional electrodes separated by a finite distance on a surface of the anodic current collector such that portions of the surface of the anodic current collector remain exposed, depositing a conformal polymeric layer over the anodic current collector and the one or more three-dimensional electrodes using iCVD techniques comprising flowing a gaseous monomer into the processing region, flowing a gaseous initiator into the processing region through a heated filament to form a reactive gas mixture of the gaseous monomer and the gaseous initiator, wherein the heated filament is heated to a temperature between about 300C and about 600C, and depositing a conformal layer of cathodic material over the conformal polymeric layer.
