【摘要】 用酚醛树脂热裂解得到的无序碳为阳极研究了在第一次循环时不可逆容量损失的原因 .实验结果表明 ,不可逆容量损失是由于溶剂分解产生了 Li2 CO3和在碳表面上形成了含—COO-基和 C—H基的化合物以及在碳主体上形成了含— OLi,— CLi化合物所致更多还原

【Abstract】 The irreversible capacity loss that occurs during the first cycle in lithium ion rechargeable batteries was studied. The experimental results show that when a disordered carbon prepared from resole resins by pyrolysis was used as a anode, the irreversible capacity loss was related to not only the solvent decomposition to form Li\-2CO\-3 and to the compounds containing \_COOH groups and \_CH groups on the carbons surface, but also to the compounds containing \_CLi or \_OLi in the bulk of carbons.更多还原
