Abstract
A system for rolling electrode plates includes: supplying units for supplying first and second electrode plates and separators; electrode processing units for forming first electrode tabs having gradually increasing intervals between tabs on one side of the first electrode plate and second electrode tabs having gradually increasing intervals between tabs on one side of the second electrode plate by performing cutting processes on the sides of the first and second electrode plates; an assembling unit for forming an electrode assembly by rolling the first and second electrode plates and the separators; and buffer units for temporarily storing the first and second electrode plates to compensate for differences in processing rates and base material transfer amounts between the electrode processing units and the assembling unit, and for transmitting the temporarily stored first and second electrode plates to the assembling unit.
