    摘要: Provided are an electrode for a secondary battery employing an active material layer having improved thickness uniformity by printing low-viscosity ink on the active material layer, a manufacturing method of the electrode, and a secondary battery having improved electrode capacity due to the employing of the electrode. The electrode includes a current collector, and an active material layer formed by printing ink having a viscosity not exceeding 500 mPa·s on the current collector and drying the current collector, wherein the current collector has a surface roughness (Ra) in a range from about 0.025 to 1.0 μm.
