Pathbreaking studies of electrochemical graphite bisulphate synthesis from artificial graphite produced from hydrolyzed lignin and further production of high quality thermal expanded graphite are described. The studies show that any oxidation level can be achieved as well as over oxidized graphite may be produced at graphite bisulphate synthesis. Parameters of graphite bisulphate synthesis and thermal expanded graphite parameters are close to those of graphite bisulphate and thermal expanded graphite produced from natural graphite's.
