Brand: Canrud
Price: 66.45 USD

Question 1

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 2

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 3

Accepted Answer

This slurry is oil-based; the solvent is NMP. (Of the slurries currently sold, only the LLTO one is water-based)

Question 4

Accepted Answer

Because this electrolyte pellet has a high lithium content, its color is deep (less lithium volatilization); the white ones have too much lithium volatilization and their ionic conductivity is not high.

Question 5

Accepted Answer

You can also coat conductive silver paste; pay attention to the composition of the conductive silver paste.

Question 6

Accepted Answer

The oxide electrolyte powders we currently sell are LATP, LAGP, LLZO, LLTO, LALZO, LLZNTO, NZSPO, and LZSPO; the oxide ceramic sheets available are LATP, LAGP, LLZTO, and NZSPO. Standard thickness is 1 mm, diameters range from 10 to 15 mm, and custom specifications can be discussed with customer service.

Question 7

Accepted Answer

Among the different types of electrolytes, oxide solid electrolytes have better resistance to water and oxygen. In particular, LATP, LAGP, and NZSPO have high water stability; LLZO, LLZTO, and LLTO are secondary. Therefore many manufacturers now perform water-resistant modification on LLZO.

Question 8

Accepted Answer

Compared with several other oxide electrolytes, LLZTO has relatively high ionic conductivity, about 8*10^-4 S/cm, and better stability against lithium metal, which to some extent suppresses lithium dendrite growth. If LLTO or LATP are used, the titanium in them is easily reduced and their stability with lithium is poor. The only issue is that they are not very stable in water, so doping modifications have been made to improve air stability while maintaining ionic conductivity.

Question 9

Accepted Answer

Yes, we need requirements for particle size, solids content, and solvent. Minimum order quantity is 5 kg, and the shelf life is one month.

Question 10

Accepted Answer

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

Question 11

Accepted Answer

LAGP, LATP, and NZSPO are water-stable. LLZO and LLTO are slightly sensitive to moisture; they can be exposed to air for short periods in a low-humidity room, but prolonged exposure will have some effect.

Question 12

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 13

Accepted Answer

Yes

Question 14

Accepted Answer

A thickness of 8–10 μm is recommended.

Question 15

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 16

Accepted Answer

At present, there are none.

Question 17

Accepted Answer

They must not be exposed to water or oxygen, though short exposures are tolerable. The surface has a passivation layer that must ultimately be polished off before gold sputtering. After polishing, transfer quickly, pump down and replace the atmosphere before sputtering gold.

Question 18

Accepted Answer

Store in a cool, dry place, sealed.

Question 19

Accepted Answer

It's the molar ratio.

Question 20

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 21

Accepted Answer

Oxide solid electrolytes like LLZO have poor interfacial stability; their surface residual base and the highly catalytic La element inside make them prone to promoting PVDF self-coupling defluorination side reactions when compounded with PVDF-type polymers. Adding EC can mitigate this side reaction, as EC reacts with the residual base first.

Question 22

Accepted Answer

LATP is stable with most cathodes; NCM811, LFP, and LCO all work. For the anode use graphite or low-silicon anodes; do not use lithium metal — LATP is unstable with lithium, and the titanium is easily reduced.

Question 23

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 24

Accepted Answer

Demand for LLZO-coated separators is currently low; they require customization. The minimum order quantity for customization is 5,000 m².

Question 25

Accepted Answer

Using LLZO would be better; for electrolyte pellets use LLZTO. Relatively speaking, LLZO is somewhat more stable against lithium metal than LAGP or LATP.

Question 26

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 27

Accepted Answer

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

Question 28

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 29

Accepted Answer

None

Question 30

Accepted Answer

This separator is composed of a PE base film, an alumina coating, and a LATP oxide electrolyte coating, and does not contain any lithium salts.

Question 31

Accepted Answer

The current maximum achievable is 4.3 mAh/cm2

Question 32

Accepted Answer

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

Question 33

Accepted Answer

No coating

Question 34

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 35

Accepted Answer

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

Question 36

Accepted Answer

This hasn't been tested. Try searching on Baidu.

Question 37

Accepted Answer

According to the content of the existing knowledge base, it is impossible to determine whether the LATP solid electrolyte slurry 300nm-B is a water system. In the case of aqueous slurries, ensure that water does not adversely affect the LATP material. This requires further reference to product-specific information to confirm.

Question 38

Accepted Answer

Yes.

Question 39

Accepted Answer

Silicon oxide (1400) and silicon oxide (1600): both of these materials have a carbon coating

Question 40

Accepted Answer

Oxide electrolyte slurries are currently available for sale: LATP, LLZO, and LLZNTO slurries. Solid content can be customized from 15% to 40%, and there are minimum order quantity requirements. For details, please refer to the official website.

Question 41

Accepted Answer

Store sealed after use in a dry environment. Some oxide solid electrolytes are slightly sensitive to moisture, but short-term exposure has no effect.

Question 42

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 43

Accepted Answer

It can function as an anode, but generally exhibits poor cycling stability and rate performance. Performance depends on voltage window and requires experimental validation.

Question 44

Accepted Answer

Ionic conductivity is on the product detail page of the official website. Some nano-scale modifications have been done, making water and air resistance slightly better. Specific details are not convenient to disclose.

Question 45

Accepted Answer

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

Question 46

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 47

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 48

Accepted Answer

There is currently no such product.

Question 49

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 50

Accepted Answer

If the electrode sheet parameters are provided, it can be calculated.

Question 51

Accepted Answer

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

Question 52

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 53

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 54

Accepted Answer

Different sizes, different manufacturers, different production processes.

Question 55

Accepted Answer

It is recommended to check whether there is surface contamination of lithium carbonate before use. If there is a history of exposure to air, it is recommended to remove the surface lithium carbonate layer by appropriate heat treatment (such as calcination at about 500°C) or surface cleaning to ensure its ionic conductivity. This recommendation is based on reasonable inferences from material properties and common industry practice.

Question 56

Accepted Answer

Currently there are no experimental conditions for this

Question 57

Accepted Answer

The electrolyte pellets are basically evenly ground at the factory, but they still need to be ground and polished before use (sanded with 2000-grit sandpaper until glossy). This is to remove the surface passivation layer of lithium carbonate and to improve surface smoothness to reduce interfacial impedance.

Question 58

Accepted Answer

Yes, this thickness will not reduce conductivity (copper foil thickness has already reached 4 μm). We’re very sorry, we have not specifically measured this and currently have no data

Question 59

Accepted Answer

Polymer electrolyte base materials are PEO and PVDF-HFP powders; you need to cast the films yourself.

Question 60

Accepted Answer

No SEM images; Na3Zr2Si2PO12 powder shows primary particles of 3–5 µm under the electron microscope, and a particle size analyzer measures 10–40 µm. Depending on the specific use: if used as filler in composite polymers there is no need to sinter, but if making oxide electrolyte pellets you need to press the green body and sinter it into ceramic pellets.

Question 61

Accepted Answer

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

Question 62

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 63

Accepted Answer

LLZTO (tantalum doped lithium lanthanum zirconium oxide) or LAGP (lithium germanium aluminum phosphate) are the best conductivity candidates among these materials, with LLZTO showing the highest conductivity in many studies. But the final result may depend on the specific experimental conditions and material preparation method.

Question 64

Accepted Answer

Prepared by the dry method.
