Abstract
A process for the production of coated carbonaceous particles including: providing a carbon residue forming material; providing particles of a carbonaceous material; mixing the carbon residue forming material and the particles of a carbonaceous material at an elevated temperature; depositing a coating of the carbon residue forming material onto the surface of the particles; and stabilizing the coated particles by subjecting the particles to an oxidation reaction. These coated carbonaceous particles are particularly useful in the manufacture of electrodes in electrical storage cells, particularly in rechargeable electrical storage cells.
