Abstract
Disclosed is a method for manufacturing a cable-type secondary battery, which includes successively supplying a first electrode member, a separator ribbon and a second electrode member around a rod-shaped winding core, wherein a width of the first electrode member and a width of the second electrode member are respectively smaller than a winding circumference, and a width of the separator ribbon is greater than the winding circumference.
Claims20
An apparatus for manufacturing a cable-type secondary battery, comprising:
- a rod-shaped winding core;
- and
- a battery element supply unit having a first electrode bobbin configured to successively supply a first electrode member, a separator bobbin configured to successively supply a separator ribbon, and a second electrode bobbin configured to successively supply a second electrode member,
- wherein at least one of the winding core and the battery element supply unit is rotated to twist the first electrode member, the separator ribbon and the second electrode member in order on a circumference of the winding core along a length direction of the winding core.

A method for manufacturing a cable-type secondary battery, comprising:
- (a) disposing a first electrode bobbin configured to successively supply a first electrode member, a separator bobbin configured to successively supply a separator ribbon, and a second electrode bobbin configured to successively supply a second electrode member, around a rod-shaped winding core;
- (b) rotating the first electrode bobbin based on an axis coinciding with an axis of the winding core to twist the first electrode member of a strip structure at an outside of the winding core;
- (c) rotating the separator bobbin based on an axis coinciding with an axis of the winding core to twist the separator ribbon at an outside of the first electrode member;
- and
- (d) rotating the second electrode bobbin based on an axis coinciding with an axis of the winding core to twisting the second electrode member of a strip structure at an outside of the separator ribbon,
- wherein a width of the first electrode member and a width of the second electrode member are respectively smaller than a winding circumference, and a width of the separator ribbon is greater than the winding circumference.
