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.
Claims14
A method of forming a precursor substance for forming an electrode of an electrochemical cell, the method comprising:
- providing particles of an electrode-forming material;
- coating the particles of electrode-forming material with an inert material to form coated particles of electrode-forming material, wherein the inert material is inert with respect to the electrode-forming material, and wherein coating the particles of electrode-forming material with an inert material comprises applying the inert material to a surface of the electrode-forming particles in a sputtering process;
- and
- mixing the coated particles of electrode forming material with a liquid or gel carrier medium to form the precursor substance.
An ink for printing an electrode of an electrochemical cell, wherein the ink comprises a mixture comprising:
- a liquid or gel;
- and
- coated particles of an electrode forming material, wherein the coated particles of electrode-forming material are coated by a sputtering process with an inert material which is inert with respect to the electrode-forming material.
A method of forming an electrode for an electrochemical cell, wherein the method comprises:
- providing a supply of coated particles of electrode-forming material, wherein the coated particles of electrode-forming material are coated by a sputtering process with an inert material which is inert with respect to the electrode-forming material;
- applying a layer of the coated particles of electrode-forming material to a medium;
- and
- forming an electrode from the layer of coated particles of electrode-forming material.
