Title:

ELECTRODE AND SECONDARY BATTERY COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2021/066494

Kind Code:

A1

Abstract:

The present invention relates to an electrode and a secondary battery comprising same, the electrode comprising an electrode active material layer, wherein the electrode active material layer comprises an electrode active material and conductive materials. The conductive materials comprise a first conductive material and a second conductive material. The first conductive material comprises secondary particles in which a part of one graphene sheet is connected to a part of another adjacent graphene sheet, wherein the secondary particles comprise a plurality of graphene sheets arrayed in different directions. The second conductive material comprises a carbon nanotube structure in which 2 to 5,000 single-walled carbon nanotube units are connected to one another, wherein the carbon nanotube structure is included in the electrode active material layer in the amount of 0.01 wt% to 0.5 wt%.
