Abstract
An electrode assembly for a lithium secondary battery and a positive electrode for the lithium secondary battery including the electrode assembly. By controlling a ratio (CR/CRi) between a content percentage of a positive electrode additive and a silicon (Si)-containing material that is a negative electrode active material, which are contained in a positive electrode mixture layer and a negative electrode mixture layer, respectively, to a specific range, the electrode assembly has an advantage in that high charging/discharging capacity and charging/discharging efficiency can be realized during initial charging/discharging, a capacity retention rate can be excellent during subsequent charging/discharging, and a lithium secondary battery including the electrode assembly can exhibit a high energy density and long lifetime.
