Abstract: Disclosed is a method for manufacturing an electrode for an energy storage device, including the steps of: (a) preparing a dry mixture of active electrode materials, for example nanoporous carbon and/or metal oxide powder, and a binder; (b) injecting the dry mixture into a carrying gas flow to form a jet of particles from a nozzle; (c) applying a high DC voltage between the nozzle and a substrate to create a high electrostatic field that provides a dense deposition of the dry mixture onto a substrate surface.
