Abstract

A positive electrode according to the present invention includes a current collector, a positive electrode mixture layer provided on a portion on the current collector and including a positive electrode active material, and an insulation layer adjacent to the positive electrode mixture layer and disposed on the current collector on which the positive electrode mixture layer is not provided, wherein the insulation layer includes a non-aqueous binder containing a solution-polymerized conjugated diene-based copolymer, and inorganic particles, so that it is possible to prevent the occurrence of cracks in a region in which the insulation layer and the positive electrode mixture layer overlap each other, and to solve the problem of electrode detachment and the phenomenon of insulation layer depression.
