  • Patent number: 10680276
    Abstract: An electrode mixture of the present invention comprises: an electrode active material; a binder; and a conductive material. When a cross-section of the electrode mixture is imaged such that a pixel filled 100% with a conductive material among a plurality of divided pixels is considered to be a condensed pixel and a value obtained by counting condensed pixels is considered to be the degree of agglomeration, the degree of agglomeration of a conductive material in the electrode mixture in the depth direction of the electrode mixture has a standard deviation less than 3.0. The electrode mixture as described above includes a conductive material uniformly distributed therein and thus has low electrode resistance. Therefore, the electrode mixture can improve output and lifespan properties of a lithium secondary battery to which the electrode mixture has been applied.
