Name: Ethylene sulfite(ES)（CAS : 3741-38-6）
Brand: Canrud

Question 1

Accepted Answer

"Vinyl sulfate" and "ethylene sulfate" are not standardized in their names, but from the context and industry habits, they usually point to ethylene sulfite (ethylene sulfite, ES). Therefore, it can be inferred that the two essentially refer to the same compound, but the naming is not accurate enough. Strictly speaking, the correct name should be "ethylene sulfite" or "ethylene sulfite".

Question 2

Accepted Answer

There is currently no CAS number available for solid products.

Question 3

Accepted Answer

It's the molar ratio.

Question 4

Accepted Answer

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

Question 5

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 6

Accepted Answer

Polyethylene oxide (PEO) is a polymeric substrate that needs to be dissolved in a solvent, have lithium salt added, and then be dried into a film. It cannot be directly pressed from powder.

Question 7

Accepted Answer

PEO itself is very stable in air, but it is generally used mixed with lithium salts, which are hygroscopic and absorb water; LATP is stable in air.

Question 8

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 9

Accepted Answer

Under normal circumstances, poly(ethylene oxide) (PEO) will become a colorless or slightly yellow liquid when dissolved; the choice of solvent also affects the color.

Question 10

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 11

Accepted Answer

PVA is soluble in water, DMSO, DMF, ethylene glycol, and propylene glycol. PVA is poorly soluble in anhydrous ethanol; at room temperature, adding PVA to anhydrous ethanol will not dissolve the PVA particles no matter how long you stir, and they remain as solid suspensions in the ethanol. Even with increased temperature, the improvement in PVA solubility in anhydrous ethanol is very limited.

Question 12

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 13

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 14

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 15

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 16

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 17

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.).
