1. An electrode for an all solid-state battery, comprising:
an electrode current collector; and
an electrode active material layer formed on at least one surface of the electrode current collector,
wherein the electrode active material layer comprises
electrode active material particles,
a solid electrolyte coated on at least part of a surface of the electrode active material particles to connect the electrode active material particles to each other, wherein the solid electrolyte consists of a polymer-based solid electrolyte formed by adding polymer resin to a solvated lithium salt, comprising polyethyleneoxide and lithium salt,
a linear structure distributed between the electrode active material particles,
wherein the linear structure comprises halloysite nanotube,
wherein microporous channels are formed between the electrode active material particles and the linear structure,
wherein the microporous channels are in communication with the outside of the electrode to provide a gas flow path, through which gas within the electrode can be discharged out of the electrode,
wherein the linear structure is 3 μm to 100 μm in length;
wherein the linear structure has an aspect ratio of 3 or more, and
wherein the linear structure exhibits a tensile strength in a range of 10 MPa to 100 MPa.
