Question 1

Accepted Answer

There is currently no CAS number available for solid products.

Question 2

Accepted Answer

Confirm the voltage window of this fluoride. If it is conventional, LPSC or LLZO are fine; if it is high-voltage, prioritize LLZO.

Question 3

Accepted Answer

It is inferred based on the design and function of the CAS number.

Question 4

Accepted Answer

The CAS number for N-methylpyrrolidone is 872-50-4, which is a direct and unequivocal conclusion based on the information provided.

Question 5

Accepted Answer

Must be cut in a glove box. After cutting, it should be rolled using a PTFE or glass rod. For potassium batteries, the metal is often rolled into thin sheets after forming small spheres. Rolling can be done directly on spacers, which then serve as carriers during coin cell assembly.

Question 6

Accepted Answer

For small quantity orders we do not provide product specification sheets. Product information is available on the product page of our official website.

Question 7

Accepted Answer

Yes, succinonitrile (SN) can be used in lithium batteries. It is mainly used as a functional additive for the electrolyte to improve certain properties of the battery, such as high pressure or high temperature stability.

Question 8

Accepted Answer

Theoretically, you can think of it that way, but impurities are often not simply lithium or sodium metals, so their potentials can differ. Sometimes early reactions can passivate the surface, which is not necessarily bad. That’s also why some electrolyte film-forming additives raise the potential so they react earlier and form a good passivation film on the anode surface.

Question 9

Accepted Answer

Sulfolane (SL, CAS: 126-33-0) has a water content of ≤ 20 ppm. This is the standard control index for battery-grade products and is suitable for lithium-ion battery electrolyte systems that are sensitive to moisture. Use should keep sealed, to avoid moisture absorption caused by performance degradation.

Question 10

Accepted Answer

Based on the knowledge base provided, it is not possible to find a density value for lithium difluorooxalate borate (LiDFOB). The data is not given in the data, need to refer to other documents or the technical specifications provided by the supplier to obtain.

Question 11

Accepted Answer

Yes, trimethyl phosphate (TMP, CAS: 512-56-1) can be battery grade. As an effective flame retardant additive, it has been studied and applied in the electrolyte of lithium ion battery to improve the safety of the battery. As long as its purity, moisture (<20 ppm), acid value and other parameters meet battery-grade standards, it is a battery-grade chemical.

Question 12

Accepted Answer

The "dimethyl carbonate (DMC)(CAS: 616-38-6) electrolyte 20kg, FSI-free" product you requested corresponds to our model MA-EN-SO-0005 high purity dimethyl carbonate (DMC), with purity of 99.99, moisture ≤ 20ppm, no additives (including FSI-like substances), and is suitable for electrolyte preparation.

At present, the standard package of this product is 1kg(1000g) per bottle, and 20kg can consist of 20 bottles. We can support bulk supply, please contact the sales to confirm the delivery cycle and packaging method (if barrel or IBC is required).

Question 13

Accepted Answer

The main component of dimethyl carbonate (DMC)(CAS: 616-38-6) is dimethyl carbonate itself, with a purity of up to 99.99%, which is a high-purity organic solvent. Its chemical formula is C, H, O, and its structure is (CH, O) CO. It does not contain other additives and is a pure substance of a single component. Commonly used in lithium ion battery electrolyte preparation and organic synthesis reaction.

Question 14

Accepted Answer

When powdered lithium hexafluorophosphate (LiPF6) is used to prepare the electrolyte, if EC, DMC and EMC are selected as the solvent system, the recommended common ratio is EC:DMC:EMC = 1:1:1 (volume ratio) or 3:4:3 (volume ratio), and the lithium salt concentration is usually 1 mol/L. This formula is widely used in lithium-ion batteries, taking into account the film-forming properties, conductivity and temperature adaptability. The specific selection can be adjusted according to the actual application requirements (such as high and low temperature performance, cycle life, etc.).
