摘要: 测试分析了酚醛树脂碳化产物组装的锂离子充放电性能.实验结果表明,树脂碳化产物作为锂离子电池碳电极材料时,其碳化处理温度有一个最佳温度范围,酚醛树脂碳化产物的最佳温度在700℃左右;树脂碳化产物的比表面积是影响电池充放电性能的重要因素,碳化产物的比表面积越大,电池的充放电量就越高,电池充放电量与充放电电流密度成反比.

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.
