A graft copolymer composition comprising the following structure:
wherein: Ax represents a polymer backbone having a number of polymerized monomer units x; [By] represents a multiplicity of a graft polymer side chain having a number of polymerized monomer units y, and at least a portion of the monomer units in By contains a group —C(O)OM, with M independently selected from H and alkali metals; [C] represents a multiplicity of positions on the polymer backbone Ax where the graft polymer side chain B or any other graft polymer side chain is not attached; the subscript w represents a grafting density of the group By, wherein w is an integer within a range of 10-50%; and the subscript z represents a density of the group C, wherein z=(100−w) %. The invention is also directed to lithium-ion batteries in which the above-described composition is incorporated in an anode of the battery.
