Question 1

Accepted Answer

Currently, the sulfide electrolyte powders we have on sale are Li6PS5Cl, Li5.5PS4.5Cl1.5, Li5.3PS4.3Cl0.8Br0.7, Li3PS4, Li7P3S11, and LGPS.

Question 2

Accepted Answer

Consider using electrolytes with relatively soft particulate textures; under pressure their interparticle interface impedance and grain boundary impedance are smaller, such as sulfides and halides. However, in general, sulfides can serve as electrolyte layers, while halide electrolytes are often used as ion-conducting additives in cathode materials. Currently, the sulfide electrolyte powders we have on sale are Li6PS5Cl, Li5.5PS4.5Cl1.5, Li5.3PS4.3Cl0.8Br0.7, Li3PS4, Li7P3S11, and LGPS. The halide is Li3InCl6.

Question 3

Accepted Answer

Comparing solvent polarity, sulfide electrolytes are more stable in nonpolar solvents.

Question 4

Accepted Answer

Sulfide electrolytes are synthesized as plates; after refinement processes to control particle size, they are not sieved.

Question 5

Accepted Answer

Not yet commercially produced.

Question 6

Accepted Answer

Particle size analyzer measured; under conditions of a drying oven with a dew point below -50°C, short-term rapid testing is fine.

Question 7

Accepted Answer

None at the moment.

Question 8

Accepted Answer

Not used as the primary electrolyte layer; it is generally used as an ion-conducting additive in the cathode. It can be directly paired with cathode materials such as LCO and NCM622, and the cathode material surface does not need coating.

Question 9

Accepted Answer

As a polymer electrolyte matrix, it is combined with other components, for example lithium salts, fillers, polymers, etc.

Question 10

Accepted Answer

There is currently no such product.

Question 11

Accepted Answer

Different manufacturers and preparation processes; purity is all 99.9%. Can be used as precursor materials for sulfide electrolytes or cathodes for Li–S batteries. Specific electrochemical performance has not been tested and is unclear.

Question 12

Accepted Answer

Which system do you want to work on? Sulfide or oxide? For oxide systems use LLZO; for sulfide systems use LPSC.

Question 13

Accepted Answer

Sulfide and halide electrolyte systems can use lithium-indium as the negative electrode, but oxide systems are more suitable for graphite and low-silicon negative electrodes.

Question 14

Accepted Answer

Yes.

Question 15

Accepted Answer

Store in a cool, dry place, sealed.

Question 16

Accepted Answer

NASICON-type solid electrolyte, such as Na₃Zr₂Si₂PO₁₂.Kaolinite-based solid electrolyte, which is more suitable for aqueous zinc-ion batteries.

Question 17

Accepted Answer

It's the molar ratio.

Question 18

Accepted Answer

The film used in the tableting process was carbon coated aluminum foil.

Question 19

Accepted Answer

If lithium salt is added, evaporation must be done in a glovebox; lithium salts must not contact water, as they are hygroscopic and deliquescent.

Question 20

Accepted Answer

The slurry formulation for the coating is different

Question 21

Accepted Answer

There are currently no all-solid-state films; oxide sheet separators are available. Finished sulfide pure solid electrolyte films are under development and will be launched soon—stay tuned.

Question 22

Accepted Answer

Not listed yet; they will be launched later. Please stay tuned.

Question 23

Accepted Answer

It’s best not to use graphite crucibles or graphite-lined furnaces. During the sintering of lithium-ion solid electrolyte pellets, lithium volatilization occurs; the exact species are unclear, and the volatiles can affect the furnace. The same applies to crucibles—the lithium volatiles can reduce crucible lifespan. Graphite crucibles may also contaminate the material, and atmosphere control during sintering would need to be more stringent. Commonly used crucible materials are platinum, alumina, and magnesia.

Question 24

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 25

Question 26

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 27

Accepted Answer

Only polymer matrix powder, no finished polymer film.

Question 28

Accepted Answer

Yes, it is stable in air and moisture; it just depends on whether other materials in the experiment require environmental control.

Question 29

Accepted Answer

The information on the official website is what it is; if it's not there, it's not there.

Question 30

Accepted Answer

Oxide solid electrolyte powders are themselves formed by sintering. There are several uses: (1) make into a slurry to coat separators; (2) mix into the cathode as an additive to enhance ion conduction; (3) press the powder into green bodies and then sinter to make discs for cell assembly. Note: green bodies made by pressing oxide electrolyte powder have excessively high grain boundary resistance and cannot be used directly for cell testing; (4) use as fillers in composite polymer electrolytes.

Question 31

Accepted Answer

If it needs firing, a binder must also be added.

Question 32

Accepted Answer

None

Question 33

Accepted Answer

Lithium cobalt oxide (high-voltage type) - Z-4.45V

Question 34

Accepted Answer

No coating

Question 35

Accepted Answer

What is the purpose of the experiment? For preparing composite electrolyte membranes, choose the solvent based on the lithium salt used; you can consider DMAC   acetone. Of course, for specific solvent selection and usage, consult relevant literature for your experiment.

Question 36

Accepted Answer

The slurry is generally used for coating separators or added into the cathode as an ion-conducting additive. Electrolyte pellets can be assembled into button cells, pouch cells, or used for research into novel batteries such as seawater batteries.

Question 37

Accepted Answer

LATP solid electrolyte coating separators can theoretically be used with liquids. (If the anode is lithium metal, the LATP-coated side should face the cathode)

Question 38

Accepted Answer

High molecular weight, narrow molecular weight distribution, low catalyst residue, can be completely dissolved in water.

Question 39

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 40

Accepted Answer

An aqueous slurry for cathode materials has not yet been developed.

Question 41

Accepted Answer

Two approaches: pressing and sintering into dense pellets; or slurry coating with binder and solvent, which usually requires additional liquid electrolyte due to limited density.

Question 42

Accepted Answer

Currently commonly used are graphite, silicon–carbon, and lithium metal anodes. Silicon–carbon options use low silicon content to avoid excessive volume expansion. For lithium metal anodes, serious lithium dendrite growth must be considered in applications; lithium–indium alloy can be used to suppress the longitudinal growth of lithium dendrites to some extent.

Question 43

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 44

Accepted Answer

"1~3um" represents the particle size range of the sulfide LPSCI lithium ion solid electrolyte powder, I .e. the size distribution of most particles is between 1 and 3 microns. This is obtained by synthesis and refinement process control, not the result of sieve classification. This interpretation is inferred based on information in the knowledge base about particle size descriptions and preparation processes.

Question 45

Accepted Answer

Powder can be made into discs; you need to consult the literature for fabrication methods. Discs cannot be reused

Question 46

Accepted Answer

A thickness of 8–10 μm is recommended.

Question 47

Accepted Answer

This is basically the same usage method as graphite anodes.

Question 48

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 49

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 50

Accepted Answer

We haven't weighed it precisely. If using the powder-burying method, a relatively large amount is needed to fully cover the pellet.

Question 51

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 52

Accepted Answer

The intermediate layer electrolyte between it and the anode is generally LPSC (Li6PS5Cl is more stable, micron-sized; nanopowder reacts somewhat more with lithium metal). When assembling the two electrolyte layers apply a relatively large pressure, about 300 MPa, to ensure the electrolyte layers are highly dense; after adding the lithium anode the applied pressure should be very low to avoid instability at the LPSC//LiIn interface.

Question 53

Accepted Answer

It is not a polymer. It is a sintered ceramic oxide and can be used directly.

Question 54

Accepted Answer

Among these three separators, the most suitable for high-rate batteries are:

✅Double-sided single-coated ceramic separator (2μm CCS 9μm PE 2μm CCS)

Followed:

🟡LATP solid electrolyte coating separator GMSS01(L2 9 2um) -if its ionic conductivity is indeed effectively utilized, the future potential is greater, but the current process maturity may not be as good as ceramic coating.

❌Meta-aramid coated isolation film (9μm PE 3μm aramid)-Although the safety is high, but because of the aramid itself non-ionic conductor, easy to cause ion transmission obstacles, is not conducive to high-rate discharge.

Therefore, it is recommended to choose a double-sided ceramic coated separator, which maintains good ion transmission while improving thermal stability and wettability, and is currently the most balanced and widely used solution for high-rate batteries.

Question 55

Accepted Answer

Electrolyte must be added, because this is not a pure solid electrolyte membrane; the intermediate base film is polyethylene (PE), which requires electrolyte to transport lithium ions.

Question 56

Accepted Answer

The sintering temperature of LLTO is generally around 1100–1300°C; the optimal sintering temperature needs to be determined experimentally — we can only provide a rough reference range.

Question 57

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 58

Accepted Answer

Different sizes, different manufacturers, different production processes.

Question 59

Accepted Answer

It depends on the intended use. If it is for assembling pellet cells for electrical testing, the powder needs to be pressed into green bodies, then sintered into ceramics, and finally ground and polished for use. The green body can be made without adding other substances, or sintering aids, binders, etc. can be added. If used as a filler for polymer composite electrolytes, it can be added directly, or the particle size can be controlled according to experimental requirements before use.

Question 60

Accepted Answer

Yes

Question 61

Accepted Answer

At present, there are none.

Question 62

Accepted Answer

You can try ball-milling the LATP powder in anhydrous ethanol or isopropanol to increase the powder surface activity, then dry it before pressing and sintering. Alternatively, add a PVA binder solution; this requires adding a drying temperature hold and a binder burn-out hold during the sintering process, for example 100°C for 1 h and 500°C for 1 h, then raise to the sintering temperature. This is for reference only; specific parameters need experimental investigation.

Question 63

Accepted Answer

We haven’t tested it, but based on the material’s properties it may be possible; however, no one here has used it that way before. We recommend that if the researcher plans to study this, they should perform their own experiments to see the effects.

Question 64

Accepted Answer

The main differences between LLZO lithium lanthanum zirconium oxide solid electrolyte (400nm) and (3um) are particle size, tap density and powder physical properties. The 400nm product has finer particles, low tap density and large specific surface area, which is suitable for applications requiring high dispersion or densification of sintered precursors, while the 3μm product has larger particles and high tap density, which is conducive to powder processing and molding. Both are comparable in ionic conductivity, about 2 mS/cm. Therefore, the choice of which product depends mainly on the specific experiment or application of the powder particle size and accumulation performance requirements.
