Dispersion agent

YK-L01 dispersion agent for lithium cathode material

Non-ionic polymer containing conjugated functional groups as anchoring groups and polar solvation chains. It can be adsorbed on the surface of the positive electrode material particles such as LFP to produce an adsorption layer of sufficient thickness, and prevent the mutual aggregation of the particles through steric hindrance to obtain a low viscosity and stable positive electrode slurry.

● Appearance: Yellow Liquid

Product Description

Non-ionic polymer containing conjugated functional groups as anchoring groups and polar solvation chains. It can be adsorbed on the surface of the positive electrode material particles such as LFP to produce an adsorption layer of sufficient thickness, and prevent the mutual aggregation of the particles through steric hindrance to obtain a low viscosity and stable positive electrode slurry.

Main Features

  • The solid content of positive slurry can be significantly increased.
  • The amount of solvent NMP can be reduced;
  • Can reduce comprehensive energy consumption and cost;
  • Can obviously improve the machining performance of the pole sheet.
  • It does not affect the electrochemical performance of the battery such as resistivity, gram capacity, charge and discharge.
