THE COMPOSITIONS AND CONSTRUCTIONS AS WELL AS CHARGE AND DISCHARGE PROPERTIES OF THE CARBONS DERIVED FROM MACROMOLECULE DOPED BY DIFFERENT IONS

The polystyrene cation exchange resin was exchanged by La 3+ ,Ni 2+ ,Li + ions and then carbonized to make carbon materials. The compositions and constructions of the resin carbon materials were analyzed. The charge and discharge properties of the resin carbon materials as the electrodes of lithium ion cells were also tested. Results indicate that doping ions into resin has catalysis effect for sulfur removal from resin in carbonized process, and the higher valence the metal ion, the more remarkable the catalysis eaffect. It is also found that doping of metal ions has promoted the preferred orientation of graphite crystallite in the lengthway direction. The electrochemical test demonstrated that there is obvious law for the capacity of the charge and discharge of the resin carbon materials doped by different valence metal ions, the capacities of the charge and discharge increase gradually with the valence of doping metal ions.
