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
