Electrode, and method for producing battery and electrode
View Patent ↗Disclosed is an electrode. An electrode according to the present invention includes an active material layer; and a current collector which includes a plurality of conductive filaments, wherein at least one from among the plurality of conductive filaments is embedded in the active material layer so that a set length is exposed from the surface thereof.
1. A method of manufacturing an electrode, comprising:
applying an active material slurry on a metal thin film;
embedding a plurality of conductive filaments in the active material slurry applied on the metal thin film; and
subjecting the active material slurry embedded with the plurality of conductive filaments to heat treatment at a predetermined temperature to separate the active material slurry embedded with the plurality of conductive filaments from the metal thin film.
2. The method of claim 1 , wherein the plurality of conductive filaments include metal fibers, carbon fibers, or carbon nanotubes.
3. The method of claim 1 , wherein the active material slurry includes sulfur (S) or a sulfur compound, and the sulfur compound is an S—C compound or an S-M compound wherein M comprises one or more of Fe, Ni, Ti, Co, and Mn.
4. The method of claim 1 , wherein the heat treatment is carried out at 300° C. to 500° C.
