▎ 摘　　要

NOVELTY - The aqueous agglomerant comprises high-hardness aqueous polymer agglomerant and high-flexibility aqueous polymer agglomerant, where the high-hardness aqueous polymer agglomerant is polymerized from water-soluble monomer with aggregate point of higher than 0℃. The high-flexibility aqueous polymer agglomerant is polymerized from water-soluble monomers with aggregate point of lower than 0℃. The mass ratio of the high-hardness aqueous polymer agglomerant to the high-flexibility aqueous polymer agglomerant is 95:5-5:95. USE - Aqueous agglomerant for positive electrode material of lithium ion battery (both claimed) for electric tool, electric toy, hybrid electric vehicle, and pure electric vehicle. ADVANTAGE - The aqueous agglomerant has high toughness, strong adhesive force, so that the prepared positive electrode has high flexibility and high adhesive force. The conductive agent is tightly combined, which is effective for the movement of the lithium ion, reduces the battery internal resistance, and improves the discharge rate and cycle performance of the battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a positive electrode material which comprises positive electrode active material, conductive agent, agglomerant, and solvent, where the solvent is water, and the agglomerant is aqueous agglomerant; and (2) a lithium ion battery. DESCRIPTION OF DRAWING(S) - The drawing shows a low-temperature discharge performance curve under -20 of the lithium-ion battery. (Drawing includes non-English language text)
