Patent ID: 8603195

Claim:
A method of producing an energy storage device, comprising: 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; selectively depositing an insulator layer on the exposed portions of the surface of the anodic current collector such that portions of the one or more three-dimensional electrodes remain exposed; depositing a conformal polymeric layer over the insulator layer and the exposed portions of 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 300° C. and about 600° C., wherein the insulator layer prevents deposition of the conformal polymeric layer onto the surface of the anodic current collector; depositing a conformal layer of cathodic material over the conformal polymeric layer; and depositing a cathodic current collector over the conformal layer of cathodic material.
