NEGATIVE ELECTRODE WATERBORNE SLURRY COMPOSITIONS FOR LITHIUM ION ELECTRICAL STORAGE DEVICES
Abstract:
The present disclosure provides a negative electrode waterborne slurry composition comprising a binder; optionally a dispersant comprising a copolymer comprising (a) constitutional units comprising the residue of a monomer comprising a nitrogen-containing heterocycle and (b) constitutional units comprising the residue of an alkyl ester of a (meth)acrylic acid and/or the residue of an acid-functional ethylenically unsaturated monomer, wherein the dispersant comprises 1% to 50% by weight of constitutional units comprising the residue of a monomer comprising a nitrogen-containing heterocycle and the % by weight is based on the total weight of the dispersant; a negative electrode active material; optionally a poly(2-alkyl or aryl oxazoline) polymer, wherein at least one of the dispersant and the poly(2-alkyl or aryl oxazoline) polymer are present; and an aqueous medium. Also disclosed are negative electrodes and electrical storage devices.
