1. A method for forming an electrode for an anode or a cathode, comprising:
providing a first source of bulk particles consisting of deagglomerated binder particles having a primary particle size of 100-1000 nm;
providing a second source of bulk particles consisting of active material particles;
mixing the deagglomerated binder particles and the active material particles to form a plurality of dry mixed composite particles wherein the deagglomerated binder particles surround each of the active material particles;
electrostatic depositing of the plurality of dry mixed composite particles onto a surface of a conductive substrate or onto a layer that is bound to the surface of the conductive substrate;
wherein the one or more active particles are positive active particles or negative active particles.
