Electrode material based on multilayer graphene oxide for chemical current sources

The results of the studies of the electrochemical synthesis of multilayer graphene oxide were presented, and the possibility of using it as an electrode material of the supercapacitor was shown. In an alcohol suspension the thickness of the particles of multilayer graphene oxide was less than 0.1 μm with an area of more than 100 μm2. The graphene oxide-based electrode has a high specific capacity of 107 F⋅g − 1 and a high charge retention rate of 97% after 5000 cycles.

Graphite Bisulphate and Thermal Expanded Graphite from Lignin

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. The article also describes results of microstructure and element analysis of thermal expanded graphite as well as its granulometric composition. The product is promising as a component of active masses for electrodes of chemical sources of current.
