| description | The invention discloses a dispersing agent for lithium ion battery slurry and application of the dispersing agent, and relates to the technical field of lithium ion batteries. The dispersing agent for the lithium ion battery slurry comprises the following components in percentage by mass: 25%-80% of R (CH2CH2O) nPO3H2, 15%-50% of organic amine and 0%-50% of a lubricating and softening agent, wherein R is a long-chain alkyl group, and n is 1-50. The dispersing agent for the lithium ion battery slurry simultaneously contains amido with positive charges and phosphate groups with negative charges, can be effectively adsorbed on the surfaces of solid particles through an electrostatic effect so as to reduce the viscosity of the slurry, and contains oleophylic long-chain groups to form effective steric hindrance in the slurry; the steric effect and the electrostatic effect act at the same time, so that solid particle sedimentation can be effectively prevented, the viscosity of the slurry is reduced, viscosity rebou |
