Novel coating compositions are disclosed for use in Energy Storage devices and Additive Manufacturing. The coatings are comprised of discrete carbon nanotubes wherein the coatings have a selected range of porosity, and optionally the discrete carbon nanotubes have selected surface modifications to improve wetting or flow of material through the pores of the carbon nanotube coating. The coatings have less than about 20% mass of bundles or ropes of carbon nanotubes with a dimension larger than about 5 micrometers The coatings are of average thickness from about 5 nanometers to about 2000 nanometers and can be applied onto particles of diameter less than about 1000 micrometers, or films. Improved energy storage, or additive part performances include, but not limited to, higher electron conductivity for electrodes of energy storage devices, and higher electron conductivity for parts made by additive manufacturing. The coatings are particularly suitable for additive manufacturing of energy storage devices, and electrodes made using a dry electrode process.
