Using methyl methacrylate(MMA),butyl Acrylate (BA),2-ethylhexyl acrylate (2-EHA),blocked isocyanate-based monomer,and dextran as main raw materials,sodium dodecyl sulfate (SDS) and fatty alcohol polyoxyethylene ether (AEO-9) as emulsifiers,the polyacrylate-dextran waterborne cathode adhesive for lithium batteries was prepared by emulsion polymerization.The obtained waterborne cathode adhesive was characterized by infrared spectroscopy,DSC analysis and thermogravimetry.The surface morphology of the cathode was characterized by scanning electron microscopy,and the electrochemical properties such as electrode impedance and cycle life of the battery were studied.The results indicated that the polyacrylate-dextran waterborne cathode adhesive for lithium batteries had a good stability in terms of the electrochemical performance of the battery electrode.
