Self-standing film for anode of lithium secondary battery, and method for manufacturing the same

Abstract

A self-standing film for an anode of a lithium secondary battery, the self-standing film including an anode active material, a conductive material, a first binder containing a triblock copolymer, and a second binder containing a fluorine-based resin, wherein the triblock copolymer includes a soft block derived from aliphatic or cycloaliphatic diene-based monomers and exhibiting a rubber phase at room temperature, and a first hard block and a second hard block each connected to both ends of the soft block, derived from an aromatic ring-containing ethylenically unsaturated monomer, and exhibiting a glass phase at room temperature, and the first binder is in the form of a non-continuous column connecting between any one of a domain of the anode active material or a domain of the conductive material and another one of a domain of the anode active material or a domain of the conductive material.
