STUDY ON IRREVERSIBLE CAPACITY LOSS IN LITHIUM ION RECHARGEABLE BATTERIES

The irreversible capacity loss that occurs during the first cycle in l ithium ion rechargeable batteries was studied. The experimental result s showed that binder was a major influential factor for forming the ir reversible capacity loss using disordered carbon as an anode material. Decomposition reactions of the binder during the first cycle were con firmed by X-ray photoelectron spectroscopy(XPS). A better binder was s uggested for disordered carbon as an anode material.
