Abstract
A manufacturing device of a fiber-type electrode includes: a bath including a coagulant; a transport portion including a supply roll provided outside the bath, a take-up roll provided inside the bath to be immersed in the coagulant, and a winding roll provided outside the bath, and configured to transport a fiber-type substrate; and a nozzle between the supply roll and the take-up roll. The nozzle includes a guide pipe that provides a moving passage of the fiber-type substrate, an inner main body around the guide pipe and that provides a central axis space in which an active material solution is supplied, and an outer main body around the inner main body and that provides a peripheral space in which a polymer solution is supplied.

A manufacturing device of a fiber-type electrode, comprising:
- a bath comprising a coagulant;
- a transport portion comprising a supply roll provided outside the bath, a take-up roll provided inside the bath to be immersed in the coagulant, and a winding roll provided outside the bath, and configured to transport a fiber-type substrate;
- and
- a nozzle between the supply roll and the take-up roll,
- wherein the nozzle comprises a guide pipe that provides a moving passage of the fiber-type substrate, an inner main body around the guide pipe and that provides a central axis space in which an active material solution is supplied, and an outer main body around the inner main body and that provides a peripheral space in which a polymer solution is supplied.
A manufacturing method of a fiber-type electrode, comprising:
- providing a coagulant in a bath;
- providing a nozzle at an upper side of the coagulant, the nozzle comprising a guide pipe, an inner main body around the guide pipe, and an outer main body around the inner main body;
- transporting a fiber-type substrate so that the fiber-type substrate sequentially passes through the guide pipe and the coagulant and concurrently spinning the fiber-type substrate around an active material solution layer and a polymer solution layer from the nozzle into the coagulant;
- and
- coagulating and drying the active material solution layer and the polymer solution layer to form an active material layer and a separation layer.
