Abstract
A cathode for lithium secondary batteries coated with a slurry including an active material, a binder and a solvent, and further including a polymerization inhibitor, is disclosed. Gelation of the slurry is prevented during production of the cathode so that adhesion of the slurry is enhanced, thus achieving improved coating properties of the cathode and facilitating the coating of the slurry.
