Applications:

LFP/LMFP/lithium cobalt oxide cathode cell slurry homogenization

 

Key features

It provides steric hindrance, and adding it to the slurry can significantly reduce the viscosity of the cathode slurry. improve the fluidity of the slurry;
reduce the settling, flocculation and other adverse phenomena of slurry; improve the processing performance of slurry coating, improve the yield rate, and help reduce costs and increase efficiency;
It can increase the solid content of LFP slurry by about 4-6%; It can increase the solid content of LMFP slurry by about 6-8%; It can increase the solid content of lithium cobalt oxide slurry by about 6-8%; reduce the amount of NMP, reduce the loss in the process of NMP recovery, and help reduce costs and increase efficiency;
reduce the internal resistance of the electrode, improve the rate charging performance, and realize the fast charging function;
Electrochemical stability: 0.1V-5.0V.

 

How to use

Method 1： DispersantXOANONS ® LD 1128-20 was added to the NMP by 30:70 (XOANONS ® LD 1128-20: NMP) is stirred and dissolved, and then added to the slurry according to the recipe amount to grind and disperse together.

Method 2: After PVDF is completely dissolved, add DispersantXOANONS ® LD 1128-20, high speed dispersion until completely dissolved, and then other components are added to grind and disperse.

The system applicability of the Dispersant should be judged according to the particles and viscosity of the slurry. This product is a polymer, which can be partially used as a substitute for binders, in order to maintain the consistency of energy density, so after adding wetting Dispersant, the amount corresponding to the binder PVDF should be recalculated according to its active substance content. It is calculated as:

PVDF dosage = PVDF (amount without dispersant) - amount of dispersant added× active substance content

 

 

Suggested dosage

Amount added ( effective portion ) based on

LFP/LMFP/lithium cobalt oxide cathode material: 0.1-0.5%

The above recommended addition amount has little effect on the resistance, and the optimal addition amount needs to be determined by a series of tests.

 

Storage stability

Seal and store in a dark place. Store for 24 months in its original unopened packaging. Products that have exceeded the storage period can continue to be used after passing the inspection. The container is not completely used and must be closed immediately after use.

 

Packaging

20 kg (plastic drum lined with aluminum-plastic bag).
