Abstract

The present invention relates to an electrode including an electrode current collector, and an electrode active material layer positioned on the electrode current collector, wherein the electrode active material layer includes an electrode active material, a single-walled carbon nanotube structure, a first dispersant containing a hydrogenated nitrile-based copolymer, and a second dispersant containing a fluorine-based polymer, the single-walled carbon nanotube structure has an average diameter of 60 nm to 300 nm, and an interface resistance between the electrode active material layer and the electrode current collector, measured by a multi-probe resistance (MP resistance) measurement method, is 0.43 Ω·cm<2> or less.
