ABSTRACT:
A secondary battery includes an anode for a secondary battery, a cathode which absorbs and discharges lithium ions, and an electrolyte which is placed between the anode for the secondary battery and the cathode. The anode for the secondary battery includes an anode active material layer which absorbs and discharges lithium ions, the anode active material layer including a first layer including carbon as a chief ingredient, and a second layer including at least one first element having a theoretical capacity greater than a theoretical capacity of graphite, and at least one second element which has a theoretical capacity equal to or less than the theoretical capacity of graphite. The second layer includes particles, and the particles include the first element and the second element.
