Abstract: As a typical organic-inorganic hybrid material, polyphosphazene material has become popular in the field of porous carbon materials which can be used as electrode materials applying to super capacitors, lithium batteries and other energy storage device to obtain better electrochemical properties. Polyphosphazene microspheres covered with transition metal were prepared by a step of precipitation polymerization. Black powder is obtained after high temperature carbonization. The microstructure structures of the materials are analyzed by IR, Raman, SEM and TEM analysis technique. In the aspect of electrochemical performance, the results show that the obtained carbon materials have high specific capacitance and exhibits excellent stability. Cobalt disulfide carbon composites are a modification of the gauge mesoporous carbon materials. The carbon microspheres grow many layers of cobalt disulfide with a high specific surface area, good electrochemical performance and dimensional stability, which can be widely used in anode materials for lithium ion batteries. This experiment using polyphosphazene microspheres as carbon source, and direct hydrothermal synthesis of cobalt disulfide on the lignin surface, then through the pyrolysis made porous carbon materials. Finally, the electrochemical properties of the carbon materials were tested and analyzed. The purpose is to develop a kind of high performance lithium ion battery cathode material which can utilize polyphosphazene as carbon source.
