Abstract
Methods and apparatus relate to methods of making carbonaceous material or coating from a precursor. Oxidation of hydrocarbons forming the precursor occurs upon adding an oxidation agent to a mixture of the precursor and a solvent for the precursor. The oxidation of the hydrocarbons yields constituents that are insoluble in the solvent and may not melt. The constituents that are insoluble in the solvent may further coat solid particles, if the solid particles are provided in the mixture. Carbonization of solids recovered by separation from liquids in the mixture increases carbon weight percent of the constituents that are insoluble in the solvent. The methods result in products that provide the carbonaceous material or coating and are suitable for use in electrodes.
