Classification: CPC H  Y | IPC H

Claim 0:
1. An electrode for a secondary battery, comprising:
a current collector;
a first electrode mixture layer disposed on at least one surface of the current collector and including a first styrene-butadiene rubber; and
a second electrode mixture layer disposed on the first electrode mixture layer and including a second styrene-butadiene rubber,
wherein the first styrene-butadiene rubber and the second styrene-butadiene rubber include a repeating unit of a styrene-derived structure and a repeating unit of a butadiene-derived structure,
the first styrene-butadiene rubber contains 40 to 90 mol % of a butadiene monomer based on a total content of a monomer, and
the second styrene-butadiene rubber has a lower content of a butadiene monomer than the content of the first styrene-butadiene rubber.
