1. A preparation method of an anode slurry, comprising:
S12, mixing materials containing a plasticizer, an additive, and a solvent to form a premixed slurry B;
S13, mixing the materials containing the premixed slurry B, an anode active material, and a conductive agent to form a premixed slurry A; and
S2, mixing a styrene-butadiene rubber emulsion with the premixed slurry A;
wherein the plasticizer comprises a first functional group, the first functional group comprises at least one of a hydroxyl group, a carbonate group, and a ketone group, the additive comprises a second functional group, and the second functional group comprises at least one of a carboxyl group, a nitrile group, and an amide group.
