Study on irreversible capacity loss in lithium ion rechargeable batteries

The irreversible capacity loss that occurs during the first cycle in lithium ion rechargeable batteries was studied. The experimental results showed that binder was a major influential factor for forming the irreversible capacity loss using disordered carbon as an anode material. Decomposition reactions of the binder during the first cycle were confirmed by X-ray photoelectron spectroscopy(XPS). A better binder was suggested for disordered carbon as an anode material.
