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Li2CO3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.

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 Li2CO3 and to the compounds containing COOHgroups and CHgroups on the carbons surface, but also to the compounds containing CLi or OLi in the bulk of carbons.

Key words: Resole resins, Lithium ion battery, Irreversible capacity loss
