Abstract
An anode for a lithium secondary battery according to exemplary embodiments may include an anode current collector and an active material layer formed on at least one surface of the anode current collector and having a value of pore resistance to density within a predetermined range. Accordingly, it is possible to secure both high-capacity characteristics and high speed charging stability, thus to further improve capacity and efficiency of the lithium secondary battery.
