Anode for lithium secondary battery and lithium secondary battery including the same
Abstract:
An anode for a lithium secondary battery includes an anode current collector, and an anode active material layer formed on the anode current collector. The anode active material layer including a lower anode active material layer formed on the anode current collector and an upper anode active material layer formed on the lower anode active material layer. Each of the lower anode active material layer and the upper anode active material layer includes a first anode active material and a second anode active material having a hardness less than that of the first anode active material. A total intrusion amount of mercury to pores having a diameter of 3 nm to 10 μm in the anode active material layer measured by a mercury porosimeter is 0.27 ml/g or more.
