1. A method of electrodepositing metal on electrically conductive particles, comprising:

  • allowing a force to cause a bed of electrically conductive particles to flow across a particle contacting surface of a cathode support spaced from an anode, wherein the force has a direction and the particle contacting surface is at an angle between about 15 and 85°

    relative to the direction of the force;

    avoiding sustained contact between the particles and the anode without use of a separator; and

    providing an electrical current between the bed of particles and the anode, thereby electrodepositing metal on said electrically conductive particles as they flow across the particle contacting surface of the cathode support.
