PVP K30 (Tech-grade) Applied on The Field of Lithium Battery

Name: Polyvinylpyrrolidone (PVP K30)
Abbreviation: Povidone K30
CAS Number: 9003-39-8
Molecular formula: (C6H9NO)n
Appearance (Colour): White or off-white powder
Usage: Dispersant
PVP-K30 is an ideal dispersant for lithium positive electrode slurry. PVP-K30 molecular structure contains strong polar lactam hydrophilic group and c-c long-chain lipophilic gene, which can be well compatible with a variety of solvents. At the same time, it can be coated on the surface of particles, forming a good dispersion through the steric effect. Adding an appropriate amount of PVP-K30 to the cathode paste of lithium battery can significantly improve the dispersion of the paste, make the paste change from Newtonian fluid to non-Newtonian fluid, stabilize the viscosity of the paste to a lower level, and ultimately help to reduce the impedance of the anode and improve the performance of the battery.

PVP-K30 (tech-grade) as dispersant for cathode material of lithium batteries

Slurry is very important in lithium-ion battery production. 70% of the quality of the battery is related to the quality of the pole piece, and 70% of the quality of the pole piece is related to the quality of the slurry. Making the paste is equivalent to completing 50% of the battery, which is the core work of battery manufacturing. Lithium-ion power battery slurry is basically composed of active material, conductive agent, binder and solvent. In the pole piece preparation section, the three processes of material drying, sol and slurry directly determine the quality of the slurry.

Lithium-ion battery cathode materials are difficult to disperse evenly during the homogenization process, and dispersants need to be added. The cathode materials of lithium batteries mainly include lithium cobalt oxide, lithium manganese oxide, lithium iron phosphate, etc., due to their low conductivity, in the battery preparation process, it is often necessary to add an appropriate amount of conductive agent, such as graphene, carbon nanotube, etc., to
improve the conductivity of the cathode material.

However, due to the small particle size and large specific surface area of ultra-fine battery cathode materials, such as lithium iron phosphate, it is difficult to disperse evenly during the homogenization process, resulting in high viscosity or low solid content of the slurry, this further leads to difficulty or even impossibility of coating, so the selection of dispersant is particularly important for the dispersion of lithium-ion battery cathode slurry.
