CATHODE BINDER FOR SECONDARY BATTERY PROVIDING EXCELLENT ADHESION STRENGTH AND LIFE CHARACTERISTICS

摘要

The present invention provides a cathode binder for a secondary battery, which comprises a copolymer of hydrophilic monomer and hydrophobic monomer, which has 800-10000 cps of the viscosity of 5% solution based on the NMP solvent. The cathode binder of the present invention provides a secondary battery with excellent life characteristics by fundamentally improving the stability of the cathode from the manufacturing process of an electrode.
