Question 1

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 2

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 3

Accepted Answer

Conductive carbon: SP, CNT; binder: PVDF-5130

Question 4

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 5

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 6

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 7

Accepted Answer

Half-cell discharge data, lithium foil used as the anode

Question 8

Accepted Answer

Model code

Question 9

Accepted Answer

Aluminum foil

Question 10

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 11

Accepted Answer

A thickness of 8–10 μm is recommended.

Question 12

Accepted Answer

The melting point of aluminum foil is 660 °C.

Question 13

Accepted Answer

The slurry formulation for the coating is different

Question 14

Accepted Answer

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

Question 15

Accepted Answer

The main solvents are PC, EC, and DEC; the specific formulation is not disclosed by the technical department.

Question 16

Accepted Answer

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

Question 17

Accepted Answer

Different manufacturers vary; recommend the customer use D-3

Question 18

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 19

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 20

Accepted Answer

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

Question 21

Accepted Answer

This temperature is fine.

Question 22

Accepted Answer

In theory it's possible; generally vacuum dry at 40°C for 4 hours is sufficient.

Question 23

Accepted Answer

Refer to other iron-lithium materials; they are the same

Question 24

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 25

Accepted Answer

None

Question 26

Accepted Answer

There is related data in the electrode sheet parameters on the official website

Question 27

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 28

Accepted Answer

Both are coated; they are just different models of LiFePO4. D-3

Question 29

Accepted Answer

The LATP side faces the positive electrode. LATP is easily reduced by lithium metal.

Question 30

Accepted Answer

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

Question 31

Accepted Answer

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

Question 32

Accepted Answer

Yes.

Question 33

Accepted Answer

Yes

Question 34

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 35

Accepted Answer

No, it cannot. It needs to be cleaned off — the LFP electrodes are fully coated and it must be wiped away.

Question 36

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 37

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 38

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 39

Accepted Answer

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

Question 40

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 41

Accepted Answer

There is currently no such product.

Question 42

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 43

Accepted Answer

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

Question 44

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 45

Accepted Answer

The electrode foil is a double-sided carbon-coated aluminum foil; the other side is coated with a carbon layer

Question 46

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 47

Accepted Answer

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

Question 48

Accepted Answer

Key factors include: 1) use carbon-coated aluminum foil as current collector; 2) use CNT conductive slurry; 3) nano-sulfur is preferred over sublimed sulfur; 4) optimize slurry formulation; 5) apply light coating; 6) optimize electrolyte amount; 7) ensure correct material selection. Other improvements depend on lab-specific know-how.

Question 49

Accepted Answer

When preparing carbon-coated aluminum foil, the conductive additive is always prepared as a water-based slurry for coating.

Question 50

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 51

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 52

Accepted Answer

Different sizes, different manufacturers, different production processes.

Question 53

Accepted Answer

Yes

Question 54

Accepted Answer

We are very sorry. Our company mainly provides materials for the preparation of lithium-ion batteries; we are indeed not familiar with the specific preparation processes for battery manufacture. We apologize.

Question 55

Accepted Answer

At present, there are none.

Question 56

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 57

Accepted Answer

There is no PP film coated with LATP; what we have is a PE film coated with LATP.

Question 58

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 59

Accepted Answer

Store in a cool, dry place, sealed.

Question 60

Accepted Answer

Currently there are no experimental conditions for this

Question 61

Accepted Answer

It's the molar ratio.

Question 62

Accepted Answer

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

Question 63

Accepted Answer

Yes

Question 64
