The Synthesis and Characterization of Dispersant for LiFePO₄ Lithium Ion Battery Slurry

Abstract:

The acrylic acid copolymerized with allyl polyethenoxy ether, to produce the dispersant for LiFePO₄ lithium ion battery slurry. Taking the quality of acrylic acid as a benchmark, the orthogonal experiment was used to optimalize the burden: the acrylic acid (AA) is 100%, maleic anhydride (MA) is 10%,ethyl acrylate (EA) is 2%, sodium allylsulfonate (ALS) is 6%, allyl polyethenoxy ether (APEG1200) is 60%. The effect of dispersant concentration to slurry fluidity was studied,LiFePO4 content in pulp was 75%, graphitized carbon black was 0.75%,the optimum amount of the dispersant is 0.3wt% of the LiFePO₄, the slurry initial viscosity is 1806 mPa.s and 2337 mPa.s after 90min which meet requirements for coating technology.
