ELECTRODE FOR SECONDARY BATTERIES, AND SECONDARY BATTERY

The purpose of the present disclosure is to improve the cycle characteristics of a secondary battery. An electrode for secondary batteries according to one example of the embodiments of the present disclosure is provided with a core body and a mixture layer that is formed on the surface of the core body. The mixture layer comprises a plurality of high-density regions and a plurality of low-density regions; and the high-density regions and the low-density regions are alternately arranged in a first direction of the mixture layer, while extending in a second direction that is perpendicular to the first direction, thereby forming stripes. It is preferable that there are three or more high-density regions and three or more low-density regions.
