TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The adhesive is polyvinylidene fluoride. The content of the functional polymer is 1~10%. The concentration of function polymer solution is 1-10 %mass. The weight ratio of the composite silicate anode material, electrode conductive agent and adhesive is 100:(1-5):(1-5). Preferred Properties: The composite silicate anode material has particle size of 5~20 mu m or 50-200 nm. Preferred Process: The functional polymer is obtained by copolymerizing methyl methacrylate monomer and vinyl monomer containing transition metal ion chelating functional group, in a mole ratio of 1:1-10. Alternatively, the functional polymer is obtained by mixing methyl methacrylate monomer, vinyl monomer containing transition metal ion chelating functional group and initiator in solvent under anaerobic condition, reacting the obtained mixture by stirring at 40-80 degrees C, adding cross-linking agent to the mixture and reacting, forming a polymerisate, suction-filtering, and drying. During manufacture of composite silicate anode material, the conductive additive is dispersed in the functional polymer solution and nano silicate (I) is added to the solution.
