Abstract
The present invention relates to an electrode assembly and a secondary battery comprising same, wherein by adjusting at least one of a loading level of a positive electrode coating layer and a loading level of a negative electrode coating layer, the negative electrode coating layer can be prevented from unnecessarily increasing in capacity, and a minimum capacity ratio of a positive electrode versus a negative electrode can be maintained in order to minimize lithium precipitation according to the number of winding turns of an electrode assembly.
