Abstract
Provided is an anode for a secondary battery including: a first anode active material; and a second anode active material having relatively lower hardness than that of the first anode active material. The first anode active material and the second anode active material satisfy Relational Formula 1 0.167<RB/RA<1, and have a volume ratio of 1:0.5˜2. In Relational Formula 1, RA is an average particle size of the first anode active material, and RB is an average particle size of the second anode active material.
