摘要: 測試分析了酚醛樹脂碳化產物組裝的鋰離子充放電性能.實驗結果表明,樹脂碳化產物作為鋰離子電池碳電極材料時,其碳化處理溫度有一個最佳溫度范圍,酚醛樹脂碳化產物的最佳溫度在700℃左右;樹脂碳化產物的比表面積是影響電池充放電性能的重要因素,碳化產物的比表面積越大,電池的充放電量就越高,電池充放電量與充放電電流密度成反比.

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.
