Question 1

Accepted Answer

No. It must be handled in a controlled atmosphere.

Question 2

Accepted Answer

Although the knowledge base does not provide relevant information, according to the research progress of magnesium batteries, the following electrolyte and solvent combinations are recommended for magnesium battery systems:

-Solvents: Ether solvents are preferred, such:
-Tetrahydrofuran (THF)
-1,2-Dimethoxyethane (DME)
-Triglyme (Triglyme)

-Electrolyte system:
1. APC electrolyte: composed of MgCl₂, AlCl3 and NaCl, soluble in THF, has good reversibility of magnesium deposition (but contains chlorine, which may corrode the current collector).
2. HMDS-based electrolyte: such as Mg(HMDS)/AlCl3/DME, excellent performance but higher cost.
3. Borate or magnesium amine systems: such as Mg (BHalready) or Mg(TFSI) in DME, are relatively mild and do not contain chlorine, suitable for research applications.
4. Commercialization tendency system: Some new non-corrosive magnesium electrolytes are being developed, such as DME solutions based on magnesium bis(fluorosulfonyl)imide (Mg(FSI)), with additives to improve stability.

Recommendation: In laboratory studies, the exploration can be started from the dissolution of Mg(TFSI) in DME or THF, paying attention to strict water removal and inert atmosphere operation, and evaluating its cycle performance and interface stability in button batteries.

Question 3

Accepted Answer

There is currently no CAS number available for solid products.

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

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

The official website does not recommend or sell dilute nitric acid electrolyte. The platform mainly provides functional electrolytes (such as LiFSI-containing FEC:TEGDME system), solid electrolytes, conductive slurries, etc., which do not involve conventional inorganic electrolytes such as dilute nitric acid. If such reagents are required, it is recommended to obtain them through chemical reagent suppliers.

Question 8

Accepted Answer

Lithium electrolyte (KLD-FS15)(1.0M LiFSI in EC:DEC = 1:1) is not a 'commercial electrolyte' in the current sense '.

The reasons are as follows:
1.✅Its lithium salt is LiFSI, instead of LiPF, which is used in mainstream commercial electrolytes;
2.✅High cost, easy moisture absorption, glove box operation, not suitable for large-scale automated production;
3.✅Sales specifications are small, the customer is a university, and the positioning is clear for experimental materials;
4.✅It has not yet entered the mainstream power battery supply chain.

But it is a high-performance functional electrolyte suitable:
-Research and development of new battery systems (e. g. silicon anodes, solid-state batteries);
-High and low temperature performance optimization;
-It may serve as a technical reserve for the next generation of commercial electrolytes in the future.

👉Therefore, it is not a commercial electrolyte at present, but it represents a development direction of commercial electrolyte in the future.

Question 9

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 10

Accepted Answer

To prevent LiFSI corrosion, it is recommended to use gold-plated or inertly-treated stainless steel die components (e. g., punches, gaskets) with a corrosion-resistant current collector material (e. g., aluminum or nickel). At the same time, corrosion inhibitors (such as TMSPa) can be added to the electrolyte to enhance the protective effect. Although the knowledge base does not directly list the specific "material name", it is clear from its description that the corrosion problem is clear and can be alleviated by means of material substitution and additives.

Question 11

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 12

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 13

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 14

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 15

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.
