The present invention relates to a battery technology, and more particularly, to a current collector that may be widely used in secondary batteries and an electrode employing the same. The current collector according to an embodiment of the present invention includes a conductive substrate; and a conductive fiber layer, which is dispersed on the conductive substrate and comprises pores. The conductive fiber layer comprises a plurality of metal filaments and liner binders mixed with the plurality of metal filaments, and the conductive fiber layer is combined with the conductive substrate via the mixed linear binders.

Current collector for secondary battery and electrode using same

Provided are a non-woven fabric current collector and a method and system of fabricating a battery using the same. An electrode according to an embodiment of the present invention includes a non-woven fabric current collector including a conductive non-woven fabric sheet including a network of conductive fibers and pores for communication between a main surface and the interior thereof; and conductive patterns partially blocking the pores on the main surface of the conductive non-woven fabric sheet.

Electrode, method of fabricating the same, and battery using the same

The present invention relates to a battery technology, and more particularly, to a current collector that may be widely used in secondary batteries and an electrode employing the same. The current collector includes a conductive fiber layer including a plurality of conductive fibers. Each of the conductive fibers includes a conductive core consisting of a plurality of metal filaments; and a conductive binder matrix surrounding the outer circumferential surfaces of the conductive core.

Provided are a non-woven fabric current collector and a method and system of fabricating a battery using the same. The non-woven fabric current collector comprises a upper conductive non-woven fabric sheet and a lower conductive non-woven fabric sheet including a network of a conductive fibers; and a tension reinforcing layer that has a greater tensile strength than the conductive non-woven fabric sheets, arranged between the upper conductive non-woven fabric sheet and the lower conductive non-woven fabric sheet, mediates adhesion between the upper conductive non-woven fabric sheet and the lower conductive non-woven fabric sheet, and has pores via which the upper conductive non-woven fabric sheet and the lower conductive non-woven fabric sheet communicate with each other.
