Layer-by-layer assemblies of carbon-based nanostructures and their applications in energy storage and generation devices

An electrode for an energy storage or production device, the electrode having a thickness of at least about 10 nanometers comprising carbon-based nanostructures and defining a composition volume, each of the carbon-based nanostructures defining a nanostructure volume, wherein the total of the volumes of the nanostructures defines at least about 60% of the composition volume.
