NOVELTY - A binder composition comprises fluorine-containing binder (a) including polar functional group, fluorine-containing binder (b) which does not include polar functional group and non-fluorine-containing binder comprising repeating unit (r1) derived from polymerizable acryl monomer and repeating unit (r2) derived from polymerizable olefin monomer. The binder (a) is vinylidene fluoride-containing binder.    USE - Binder composition is used for cathode for lithium battery (all claimed). Uses include but are not limited to laptop computer, smartphone, electric vehicle, hybrid vehicle, and plug-in hybrid electric vehicle.    ADVANTAGE - The binder composition improves flexibility and adhesiveness of an electrode plate, and dispersibility of conducting agent simultaneously, and enhances adhesiveness with current collector, thereby improving the energy density and cycle life characteristics of lithium battery. The binder (a) provides excellent adhesiveness to the current collector. The binder (b) is capable of retaining an electrode structure during battery operation. The binder (c) is capable of improving electrode plate flexibility and conducting agent dispersibility. When the conducting agent is uniformly distributed in the electrode, the internal resistance of the cathode is decreased, thereby improving the life characteristics and output characteristics of the lithium battery. The uniform electrode is easily manufactured using the binder composition. The lithium battery including the binder composition has improved cycle life characteristics at high voltage of 4.3 V or more, and is capable of operating at high temperature and charging and discharging large amount of electricity, and has excellent long-term usability and lifetime. By introducing the repeating unit having linear alkylene structure into the polymer containing non-fluorine containing binder, the battery characteristics is improved when swelling of the electrode with respect to an electrolyte is optimized.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for cathode (3), which comprises a cathode active material, a conducting agent and binder composition.
