  • COMPOSITION FOR FORMING ANODE OF LITHIUM SECONDARY BATTERY
    Publication number: 20250062353
    Abstract: disclosureDisclosed are, inter alia, a composition for forming an anode of a lithium secondary battery including an anode active material, a conductive material, and a binder. Particularly, the binder contains a triblock copolymer which has a soft block derived from an aliphatic or alicyclic diene-based monomer and forming a rubbery phase at a room temperature; and a first hard block and a second hard block connected to both ends of the soft block, respectively, derived from an aromatic ring-containing ethylenically unsaturated monomer, and forming a glassy phase at a room temperature, and wherein the binder includes particles with an average diameter (D50) of 1 ?m or more and 50 ?m or less.
