SECONDARY BATTERY AND MANUFACTURING OF THE SAME

摘要

PURPOSE: A secondary battery and a manufacturing method thereof are provided to facilitate miniaturization and lighten the weight in case the secondary battery is installed on curved shape electronic devices. CONSTITUTION: A secondary battery comprises housing, electrode assembly(100), a first electrode tap(140) and a second electrode tap. The electrode assembly comprises a first electrode board reeled around a principal axis which is extended from a first direction, a separator and a second electrode board. The secondary battery has a thickness facing towards a second direction and a length of a third direction. The length has a curvature based on a secondary axis. The first electrode tap and the second electrode tap are respectively connected to the first electrode board and the second electrode board and are projected from the electrode assembly.
