Abstract: The phenolic aldehyde were carbonized to make the resin carbon.The charge and discharge performance of the lithium ion cells used the resin carbon materials as the electrodes were analyzed. The result indicated that there is an optimal carbonized temperature range for resin carbon being used as electrode of lithium ion cells. And for the phenolic aldehyde carbon, the optimal carbonized temperature is about at 700℃. The specific surface of the resin carbon is an impolrtant factor effecting on the electrochemical properties of the lithium ion cell. The bigger the specific surface of the resin carbon is, the higher the capacity of the cell.
