A lithium battery binder includes polyvinylidenefluoride(PVDF) having an IR absorption peak ratio of Iγ in a range from 0.35 to 1.00, wherein Iγ is equal to I820-850/I860-880 where I820-850 is a peak height resulting from a CH2 rocking band in γ-phase PVDF and I860-880 is a peak height resulting from backbones in α- and γ-phase PVDF. The lithium battery containing the cathode and/or the anode which incorporates the binder improves the charge/discharge characteristics and the lifespan characteristics of a lithium battery. |
