2 2 BINDER COMPRISING RANDOM COPOLYMER ANODE FOR LITHIUM-ION SECONDARY BATTERY COMPRISING THE SAME LITHIUM-ION SECONDARY BATTERY COMPRISING THE ANODE AND METHOD FOR POLYMERIZING THE COPOLYMER

摘要

The present invention is a hydroxyalkyl (meth) acrylate monomer; at least one selected from (meth)acrylic acid monomers and alkali metal salt monomers of (meth)acrylic acid; And (meth) comprising a copolymer of monomers comprising an acrylonitrile monomer, The copolymer is a binder, characterized in that it does not contain a conjugated diene monomer, a fluorine-containing (meth) acrylic acid ester monomer, and starch, a negative electrode for a lithium ion secondary battery comprising the same, and a lithium ion secondary battery including the negative electrode to provide. In addition, the present invention provides a polymerization method of the copolymer.
