A method for making crystalline graphite composite includes the following steps: additives are dry blended with a melt-flowable polylignin to form a blend. The blend is heated to create a melted flowable polylignin with the additives dispersed therein. The melted flowable polylignin is then solidified to a grindable form or to a shaped article of polylignin with dispersed additives, after which sufficient heat is provided to thermoset and carbonize the polylignin with dispersed additives. Additional heat is then provided to graphitize the carbonized polylignin and form a crystalline graphite matrix with uniformly dispersed additives.
