More Information
Summary:A binder includes a polyacrylate copolymer and a lithium-containing compound. A preparation method of a binder includes adding monomers of a polyacrylate copolymer to a first emulsifier solution to obtain a pre-emulsion, adding an initiator to the pre-emulsion for reaction to obtain a reaction solution, and adding a lithium-containing substance to the reaction solution to adjust pH value to 7 to 8 and performing filtering to obtain the binder.
