A lithium battery binder includes polyvinylidenefluoride(PVDF) having an IR absorption peak ratio of I.sub..gamma. in a range from 0.35 to 1.00, wherein I.sub..gamma. is equal to I.sub.820-850/I.sub.860-880 where I.sub.820-850 is a peak height resulting from a CH.sub.2 rocking band in .gamma.-phase PVDF and I.sub.860-880 is a peak height resulting from backbones in .alpha.- and .gamma.-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.
