LA133 aqueous binder is the water dispersion of acrylonitrile multi-copolymer, it has good antioxidant and anti-reduction ability and can be applied to a variety of cathode and anode materials(including LiCoO2、LiMn2O4 and LiFePO4 cathode material、carbon anode material and activated carbon)
LA133 has a relatively high viscosity compared to LA132 and has a better suspension ability to powder materials.
LA133 aqueous binder has a high viscosity and pure quality, thickener and organic solvent are not needed while using it, so the cost of materials can be reduced effectively, at the same time, the environmental pollution caused by solvent-based binder during the production of lithium-ion battery and poor safety can also be effectively avoided.
The lithium-ion battery which uses LA133 aqueous binder has excellent cycle performance and rate capability, the cell polarization is slight.
