Electrostatic assembly methods have been used to generate a range of new materials systems of interest for electrochemical energy and storage applications.   Over the past several years, it has been demonstrated that carbon nanotubes, metals, metal oxides, polymeric nanomaterials, and biotemplated materials systems can be incorporated into ultrathin films to generate supercapacitors and battery electrodes that illustrate significant energy density and power.     The unique ability to control the incorporation of such a broad range of  materials at the nanometer length scale allows tailoring of the final properties of these unique composite systems, as well as the capability of creating complex nanoporous morphologies based on the scale of the nanomaterial that is absorbed within the structure, or the conditions of self-assembly.     Recently we have expanded these capabilities to achieve must thicker electrodes via Spray-layer-by-layer and filtration methods that enable the generation of electrode systems with unusually high surface and porosity, while maintaining significant active material within the electrode structure.   Templating of nanostructured thin LbL films on macroscopic porous templates such as electrospun mats has ultimately led to additional means of creating novel materials for supercapacitor applications.   These methods will be discussed in detail, as well as the performance characteristics of the resulting energy devices.
