Abstract
The present invention relates to an electrode comprising multi-layered electrode active material layer and a secondary battery comprising the same. According to the embodiments of the present invention comprises electrode having multi-layered electrode active material layer, wherein the content of the active materials which forms the electrode active material layers is equally maintained and the loading amounts at each layer are either the same or different from each other, thereby solving the problem of performance deterioration caused by an increase in battery resistance due to non-uniform dispersion of a binder or the like.
