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

It is recommended to use NaPF6 dissolved in EC/DMC/DEC solvent system, and add a small amount of ionic liquid or fluoride additive electrolyte. This electrolyte system can provide higher ionic conductivity, better interface stability and oxidation resistance, and is suitable for use with sodium-oxygen cathode materials (such as O3 or P2 type). If higher thermal stability and cycle life are required, NaFSI or NaTFSI may be considered as the electrolyte.

Question 6

Question 7

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 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

There is currently no such product.

Question 10

Accepted Answer

Not yet commercially produced.

Question 11

Accepted Answer

Yes

Question 12

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 13

Accepted Answer

None at the moment.

Question 14

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 15

Accepted Answer

We tested it in a half-cell; theoretical gravimetric capacity >95 mAh/g

Question 16

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 17

Accepted Answer

Use fiberglass/regular PE film/alumina ceramic separator, or for all-solid-state use NZSPO.

Question 18

Accepted Answer

For sodium batteries, separators generally use glass fiber separators GF-D, or you can directly use lithium battery separators.

Question 19

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 20

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 21

Accepted Answer

For sodium batteries, it is recommended to use glass fiber / regular thick PE / alumina ceramic separators, or for all-solid-state use NZSPO ceramic sheets.

Question 22

Accepted Answer

Symmetric cells generally do not add electrolyte; if it is an all-solid-state cell, to test performance you can add a little.

Question 23

Accepted Answer

It can be used directly; preferably vacuum bake at 85°C for 6 hours

Question 24

Accepted Answer

No. Currently available products are polymer matrix powders such as PEO, PVDF-HFP, and various lithium/sodium salts.

Question 25

Accepted Answer

Our dry cells have all been baked and can be filled with electrolyte directly.

Question 26

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 27

Accepted Answer

It's because of conductivity issues. Cathode materials themselves have poor conductivity, so they are generally coated.
