Abstract
A method for coating particulate substrate materials is provided which comprises (a) combining particles and an electrolyte in an imperforate container; (b) vibrating the container to generate a fluidized bed of particles in the electrolyte; and (c) electrochemically depositing a coating on the particles from reactants in the electrolyte. An apparatus for coating particles is also provided which comprises an imperforate container for receiving particles to be coated and an electrolyte and a device for generating a fluidized bed in the container, the device being operatively associated with the container.
Claims19
A method for coating particulate substrate materials comprising:
- combining particles of a particulate substrate material and an electrolyte in an imperforate circular container including a particle pathway comprising a recessed annular portion;
- vibrating said container to agitate said particles to generate a fluidized bed of said particles in the electrolyte, wherein the fluidized bed of said particles is a dense fluidized bed of said particles which is in continuous contact with said recessed annular portion;
- and
- electrochemically depositing a coating on the particles from reactants in the electrolyte.
