Abstract: A method of forming a precursor substance for forming an electrode of an electrochemical cell. The method comprises providing particles of an electrode-forming material and coating the particles with an inert material to form coated particles. The inert material is inert with respect to the electrode-forming material. The coated particles are mixed with a liquid or gel carrier medium to form the precursor substance. Useful new electrochemical products are provided.

Abstract: Method of printing and articles A method of printing a separator for an electrochemical cell and articles made therefrom. A method of printing a separator for an electrochemical cell and a method of printing an electrochemical cell comprises providing an ink having particles of a separator-forming substance suspended within it and printing a layer of the ink onto a surface. The separator is formed from the separator-forming substance in the layer of ink. This may be done by drying or curing the layer of ink. The separa-tor-forming particles may host an electrolyte before or after the separator is formed.
