Abstract

The present specification discloses a technique relating to an electrode material mixture composition, wherein the electrode material mixture composition is characterized by including a binder mixture including a large-crystal binder having a crystal size of 50 nm or more and a small-crystal binder having a crystal size of less than 50 nm; and an electrode active material. The electrode material mixture composition may improve mechanical properties of a powder-sheeting film by utilizing different degrees of fibrillization by using a binder mixture in which binders having different crystal sizes are mixed, may improve processability of a calendering process, and thus may provide a secondary battery having excellent resistance characteristics.
