Abstract
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.
Claims21
An electrode comprising:
- a conductive non-woven fabric sheet comprising 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.
A method of fabricating an electrode, the method comprising:
- providing a non-woven fabric current collector, the non-woven fabric current collector comprising:
- a conductive non-woven fabric sheet comprising 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;
- impregnating an electrically active material into the non-woven fabric current collector by passing the non-woven fabric current collector through a bath filled with slurries containing a precursor of the electrically active material or a dispersing solvent thereof;
- drying the non-woven fabric current collector pulled out of the bath;
- and
- pressing the non-woven fabric current collector having impregnated thereto the electrically active material.
19-27. (canceled)
