Lithium ion battery positive electrode slurry dispersing agent, preparation method and application thereof

The invention discloses a lithium ion battery positive electrode slurry dispersing agent, which is prepared from the following components in percentage by mass: 40-80% of hydrophilic monomer, 10-20% of solvent, 10-20% of dispersing agent and the balance of solvent. 10%-20% of a hydrophobic monomer; 0.5%-5% of a functional monomer; 1%-5% of a wetting monomer; 0.5%-2% of an initiator; a pH adjusting agent; and an organic solvent. According to the lithium ion battery positive electrode slurry dispersant, the solid content of an active substance in the positive electrode slurry is improved, the higher the solid content of the active substance is, the higher the battery capacitance is, and the electrochemical stability is hardly influenced. According to the lithium ion battery positive electrode slurry dispersing agent, the dispersing agent not only has excellent dispersing capacity on the positive electrode slurry, but also enables the positive electrode slurry to have excellent stability, and a positive electrod
