Abstract
An electrode for a lithium secondary battery includes a silicon-based alloy, and has a surface roughness of about 1 to about 10 μm and a surface roughness deviation of 5 μm or less. A method of manufacturing the electrode includes mixing an electrode composition, milling the composition, coating the milled composition on a current collector, and drying the milled composition. A lithium secondary battery includes the electrode.
