摘要:
An anode for a secondary battery includes a first anode mixture layer disposed on an anode current collector and a second anode mixture layer disposed on a surface of the anode, wherein the first and second anode mixture layers include a graphite-based anode active material of graphite secondary particles, at least the second anode mixture layer includes a graphite-based anode active material of graphite primary particles, and a content [A2] of graphite primary particles included in the second anode mixture layer is greater than a content [A1] of graphite primary particles included in the first anode mixture layer.
