Abstract
An electrode plate winding device and rolling method for cylinder type battery that is to increase a battery capacity by rolling the electrode plate in a cylinder-like shape. The electrode plate winding device has a mandrel which winds electrode plates coated with the active material layers having different polarity and separators, interposed between the plates. The mandrel is of a generally round cross-section but divided into two parts by a groove. The mandrel having at least one electrode tap region formed in one of the divided parts.
