MULTILAYER ELECTRODE FOR SECONDARY BATTERY AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a multi-layered electrode for a secondary battery and a producing method thereof and, more specifically, to an electrode comprising: a first electrode mixture layer applied on a surface of a current collector; and a second electrode mixture layer applied on the first electrode mixture layer, and to a producing method thereof. Porosity of the first electrode mixture layer is greater than porosity of the second electrode mixture layer, wherein the porosity of the second electrode mixture layer is greater than or equal to 15%.
