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

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

Question 15

Accepted Answer

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

Question 16

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 18

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 19

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 20

Accepted Answer

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

Question 21

Accepted Answer

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

Question 22

Accepted Answer

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

Question 23

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 24

Accepted Answer

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

Question 25

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 26

Accepted Answer

Refer to the anode slurry stirring formulation. Check the article on anode stirring on the KeLude public WeChat account.

Question 27

Accepted Answer

rest 2h, 0.2C DC to 0V, 0.1C DC to 0V, 0.01C DC to 0V, 10 μA DC to 0V, rest 3 min, 0.1C CC to 2V — this is the first cycle gravimetric capacity test step

Question 28

Accepted Answer

rest 4h, 0.2C DC to 0V, 0.1C DC to 0V, 0.01C DC to 0V, 10μA DC to 0V, rest 3 min, 0.1C CC to 2V. This is the test procedure.

Question 29

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.).

Question 30

Accepted Answer

Recommended hard carbon capacity testing procedure: Rest 4 h, 0.2C DC to 0 V, 0.1C DC to 0 V, 0.01C DC to 0 V, 10 μA DC to 0 V, rest 3 min, 0.1C CC to 2 V.

Question 31

Accepted Answer

Stirring is recommended. If heating is necessary, do so in an anhydrous environment at 35–40 °C, with strict safety precautions due to strong oxidizing properties.

Question 32

Accepted Answer

For our sodium nickel manganese iron oxide we use our own 12 4 2 separator. For the hard carbon capacity tests, our testing procedure is: rest 2 h, 0.2C DC to 0 V, 0.1C DC to 0 V, 0.01C DC to 0 V, 10 μA DC to 0 V, rest 3 min, 0.1C CC to 2 V.

Question 33

Accepted Answer

Battery grade CMC is sodium carboxymethyl cellulose (sodium Carboxymethyl Cellulose), is a commonly used in lithium ion battery anode water-based binder. It is mainly used to stabilize the electrode slurry, improve the coating quality, and enhance the adhesion between the active material and the current collector, thereby improving the cycle life and processing performance of the battery.

Question 34

Accepted Answer

Because the sintering temperature for ceramic plates reaches 1500–1600°C, they are generally used as inorganic fillers; I haven't done it myself so I'm not familiar. 2.8–4.3 V is acceptable.

Question 35

Accepted Answer

Na3Zr2Si2PO12 is a sodium-ion-conducting solid electrolyte used in sodium solid-state battery research. Cells are assembled as button cells; the assembly structure is similar to conventional liquid electrolyte button cells, but the central separator is replaced with a solid electrolyte disc, and no liquid electrolyte is required (a very small amount of liquid electrolyte is added when testing cell performance to wet the interfaces).

Question 36

Accepted Answer

Common academic methods include: 1) removing surface oxide in a glove box, rolling into thin sheets, then punching; 2) slicing after oxide removal, placing between plastic films, and flattening with plates. Rolling directly on spacers is also recommended.

Question 37

Accepted Answer

This material itself has no capacity. The ionic conductivity hasn't been specifically measured; the data are for reference only, since this product is generally used as an inorganic filler. If you want to sinter it into a pellet to measure ionic conductivity, the sintering temperature needs to reach 1500–1600°C, which requires high-spec equipment.

Question 38

Accepted Answer

I confirmed with our engineering department that this inflection point is basically related to the electrolyte formulation; some formulations exhibit this inflection point while others do not. The specific technical details have not been fully researched by the engineering department yet.

Question 39

Accepted Answer

NZSPO — this is a relatively mainstream and mature sodium-ion solid electrolyte technology at present. Regarding stability, it is stable across a voltage range of 0–4.5 V; it is stable at high voltage, and at low voltage it undergoes some reduction and valence change, but this does not greatly affect battery performance. If examining the mechanism microscopically, the low-voltage behavior may involve valence changes at the nanolayer level.

Question 40

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.
