Question 1

Accepted Answer

Conductive carbon plus some binders

Question 2

Accepted Answer

The melting point of aluminum foil is 660 °C.

Question 3

Accepted Answer

The slurry formulation for the coating is different

Question 4

Accepted Answer

It is carbon-coated

Question 5

Accepted Answer

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

Question 6

Accepted Answer

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

Question 7

Accepted Answer

We apologize, but this is the core technology of TuTan Materials’ enterprise; the technical department does not disclose it externally.

Question 8

Accepted Answer

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

Question 9

Accepted Answer

They are all carbon-coated.

Question 10

Accepted Answer

Yes

Question 11

Accepted Answer

LiFePO₄ has low conductivity. Carbon-coated aluminum foil reduces internal resistance, improves adhesion, and helps prevent electrode cracking.

Question 12

Accepted Answer

Lithium–copper composite strip

Question 13

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 14

Accepted Answer

They are generally coated with carbon via chemical vapor deposition (CVD).

Question 15

Accepted Answer

Yes

Question 16

Accepted Answer

Hardness has not been tested. Check whether this item is listed in the material specification sheet

Question 17

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 18

Accepted Answer

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

Question 19

Accepted Answer

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

Question 20

Accepted Answer

Yes, it is surface-coated.

Question 21

Accepted Answer

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

Question 22

Accepted Answer

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

Question 23

Accepted Answer

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

Question 24

Accepted Answer

Aluminum foil

Question 25

Accepted Answer

Silicon monoxide is the anode material for lithium batteries; its surface has already been coated with carbon material; it is not pure silicon monoxide.

Question 26

Accepted Answer

It is battery-grade purity and can be used directly to assemble batteries. There is no percentage value; the material has been carbon-coated and has extremely low impurity content.

Question 27

Accepted Answer

A thickness of 8–10 μm is recommended.

Question 28

Accepted Answer

Is it all used up? Just a tiny bit of material left at the end?

Question 29

Question 30

Accepted Answer

If carbon-coated nano-silicon is required, products that are clearly labeled as having a "carbon-coated" or "silicon-carbon composite" (Si/C) structure should be selected. The materials in the current list are suitable for basic research, but may not be suitable for direct use in actual battery applications due to poor cycle stability, unless carbon coating is carried out on their own.

Question 31

Accepted Answer

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

Question 32

Accepted Answer

Our graphite anodes are all coated. Industrialized coatings are basically solid-phase, mainly coated with asphalt (this asphalt is available on our Keluode website). The specific coating process is part of the core technology for producing graphite.

Question 33

Accepted Answer

Graphite

Question 34

Accepted Answer

No coating

Question 35

Accepted Answer

Yes

Question 36

Accepted Answer

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

Question 37

Accepted Answer

None

Question 38

Accepted Answer

About 25%.

Question 39

Accepted Answer

Yes, it is multi-walled carbon nanotubes (MWCNT).

Question 40

Accepted Answer

The separators inside dry battery cells are ceramic-coated separators; baking at 85°C is fine.

Question 41

Accepted Answer

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

Question 42

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 43

Accepted Answer

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

Question 44

Accepted Answer

They cannot be baked that high; there is still concern about separator shrinkage

Question 45

Accepted Answer

Carbonate-based.

Question 46

Accepted Answer

This was provided by the original manufacturer.

Question 47

Accepted Answer

Within 200 nm.

Question 48

Accepted Answer

The density of aluminum is 2.7 g/cm3. To find the length from the mass: mass/density/width/thickness/unit conversion. Meters = 3*1000/2.7/20/0.0016/100

Question 49

Question 50

Accepted Answer

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

Question 51

Accepted Answer

Carbon cloth cannot be used directly as a lithium battery anode; it has no capacity. Anodes generally use graphite, hard carbon, silicon-carbon, etc.

Question 52

Accepted Answer

There is currently no XRD data. Normally silicon-carbon 420 shows XRD signals of both graphite and silicon.

Question 53

Accepted Answer

Currently there is niobate-coated NCM811 and lithium borate-coated NCM811; niobate-coated NCM811 is used more widely and feedback is good. There are fewer usage data for lithium borate-coated NCM811.

Question 54

Accepted Answer

This has been done before; directly coordinate with the technical department — we can weld the lithium sheets together

Question 55

Accepted Answer

The customer can make the slurry themselves; we cannot do it at present.

Question 56

Accepted Answer

Common systems: PTFE (water-based, mainly for aqueous supercapacitors); PVDF (NMP, oxide cathodes); CMC SBR (carbon-based anodes); PAALi (silicon–carbon systems).

Question 57

Accepted Answer

All finished ternary materials (111 523 622 811 series 9xx) are coated; the coating is an oxide. Specific compositions vary by manufacturer and are strictly confidential, not disclosed externally

Question 58

Accepted Answer

Yes, it is.

Question 59

Accepted Answer

Separator coating process: after coating and drying, it is finished as a product.

Question 60

Accepted Answer

Solid-state-specific carbon-group anodes are still under development; currently there are no such products. For solid-state-specific lithium metal anodes, lithium–indium alloy is available at present.

Question 61

Accepted Answer

This is determined by trial and error; different equipment will certainly require different settings.

Question 62

Accepted Answer

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

Question 63

Accepted Answer

This is basically the same usage method as graphite anodes.

Question 64

Accepted Answer

The electrolyte pellets are simply ground and polished, then gold-sputtered on both faces, leaving the edges unsputtered. The gold-coated pellet is clamped between the two faces with a coin-cell test clip for measurement.
