2. Recommendations for use

2.1. Suggested dosage of Sinodur® 25628: Ternary NCM523, NCM622 system: 1.2%-1.8%; Ternary NCM811, NCA811 system: 1.5% or more;

LFP system: 2.2%-2.8%, it is recommended to communicate fully before use;

LMO system: 1.4%-1.6%;

LCO system: 1.0%-1.2%.

Note 1: When doped with carbon nanotubes, it is recommended to reduce the above dosage by an additional 0.1% PVDF.

Note 2: PVDF is mainly used to bond positive electrode material particles, and the dosage is mainly determined based on the density and specific surface area of the positive electrode material. If the density of the positive electrode material is reduced or the specific surface area is increased by doping with manganese, cobalt, etc., the proportion of PVDF can be appropriately increased.

2.2. Instructions for use When gluing with the wet method, first quickly mechanically stir for 1.5-2 hours. If the equipment stirring rate is slow or uneven stirring prevents complete dissolution, the stirring time can be increased by 0.5-1 hour, until the PVDF is completely dissolved before entering the pulping stage. The molecular weight of Sinodur® 25628 is ≥110W, and the dissolution rate is slow.

Measures to promote its dissolution can be taken as follows:

1) Increase stirring time appropriately;

2) Increase stirring and dispersing speed appropriately;

3) Add PVDF in batches to dissolve in the stirring kettle;

4) Increase the dissolution temperature in the stirring kettle appropriately.

2.3. Product storage This product is recommended to be stored in dry, ventilated conditions, avoiding light and heat.

2.4. Other For other special usage and storage situations, please communicate promptly with our relevant personnel.
