摘要：
A method of manufacturing a dry electrode sheet for a secondary battery includes providing a dry electrode composition comprising an active electrode material and a binder, calendering the dry electrode composition with a calender roll and forming a first electrode sheet, cutting the first electrode sheet into two or more pieces, and laminating and then calendering the cut first electrode sheet.
