摘要： A preparation method includes 1) dispersing cellulose nanocrystal in water and adjusting pH to 7; 2) adding carboxylate to the aqueous dispersion of the step 1), and stirring until uniform; and 3) adding a monomer and a ceric ammonium nitrate initiator to the system of the step 2), reacting for 0.5-3 h to obtain a precipitate, and subjecting the precipitate to suction filtration, washing, and drying to obtain the cellulose nanocrystal powder. By adding a small amount of carboxylate into a cellulose nanocrystal graft polymer modification system initiated by ceric ammonium nitrate, hydrolysis of cerium ions can be inhibited through complexation of the carboxylate to the cerium ions which play an initiating role in ceric ammonium nitrate, so that ceric ammonium nitrate can initiate the polymerization reaction under acid-free conditions, thereby achieving polymerization of polyvinyl acetate monomer on the surface of cellulose nanocrystals.

摘要： A multi-functionally modified polymer binder for lithium ion batteries, which is prepared by a free radical graft copolymerization or a Michael addition reaction, with a biomass polymer or a synthetic polymer as a substrate, and a hydrophilic monomer and a lipophilic monomer as functionally modifying monomers. The binder presents a three-dimensional network body with a multi-branch structure, provides more active cites for contacting with the electrode active materials, improves uniformity and flatness in the formation of films from electrode slurry, enhances the binding strength between the electrode active materials, the conductive agents and the current collector, has high elasticity and binding strength, and is applicable in water/organic solvent. Use of the binder in positive electrodes and negative electrodes can facilitate the conduction of electrons/ions during charging and discharging, reduce the electrochemical interface impedance of the electrodes.
