Abstract
Provided is a binder for secondary battery electrodes comprising polymer particles obtained by polymerizing three or more kinds of monomers wherein the polymer particles have a mean particle diameter of 0.3 μm to 0.7 μm. The binder exhibits superior adhesion force to electrode current collectors and excellent support force to the active material and basically improves safety of electrodes, thus providing a secondary battery with superior cycle characteristics.
