Question 1

Accepted Answer

Recommend just using the most conventional graphite.

Question 2

Accepted Answer

Dry powder is pressed into green bodies in a steel mold at 250–500 MPa; the master powder is buried or directly sealed to control lithium volatilization. Sintering parameters: 1000–1300°C for 3–24 h. Sinter in an argon atmosphere, or sinter sealed in a container under conventional atmosphere. After sintering, the plates are ground. More detailed parameters need to be explored independently.

Question 3

Accepted Answer

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

Question 4

Accepted Answer

Store in a cool, dry place, sealed.

Question 5

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 6

Accepted Answer

Under dry, sealed conditions, six months to one year.

Question 7

Accepted Answer

Stored for 2 years if kept in a glovebox atmosphere and bottles are well sealed.

Question 8

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 9

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 10

Accepted Answer

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

Question 11

Accepted Answer

Yes

Question 12

Accepted Answer

Key points include: capacity balancing between cathode and anode; electrolyte compatibility; formulation to minimize polarization; proper alignment and stacking to ensure stable internal contact.

Question 13

Accepted Answer

We really haven't tested the hardness of the powder material.

Question 14

Accepted Answer

Conventional cathode and anode sheets and ceramic sheets form the battery, and there are contact interfaces that require adding a small amount of electrolyte to wet the interfaces. However, if the ceramic sheet surface is treated together with the cathode and anode material processes so that the electrode materials make better contact with the electrolyte sheet, electrolyte wetting of the interface is not necessary.

Question 15

Accepted Answer

We really haven’t tested hardness for the powder material.

Question 16

Accepted Answer

Tear open the sealed bag inside the glove box. The structure of the lithium-indium alloy is double-layer indium foil sandwiching lithium powder. Layering is normal; do not pry it apart. Normally punch out pieces of the appropriate size with a punch, assemble the cell mold, finally insert the lithium-indium alloy piece, apply pressure of 5–10 MPa, and an alloy will form within tens of seconds; of course, waiting a few minutes yields a more uniform alloy.

Question 17

Accepted Answer

Yes, their crystal structures are the same.

Question 18

Accepted Answer

Different manufacturers vary; recommend the customer use D-3

Question 19

Accepted Answer

Aqueous system

Question 20

Accepted Answer

But the solid content of the adhesive itself should be listed in the product specifications.

Question 21

Accepted Answer

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

Question 22

Accepted Answer

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

Question 23

Accepted Answer

It's single-sided

Question 24

Accepted Answer

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

Question 25

Accepted Answer

Our graphite electrode test results are on the official website

Question 26

Accepted Answer

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

Question 27

Accepted Answer

Graphite used as the anode does need a bit of conductive additive, for example Super P

Question 28

Accepted Answer

The amount of electrolyte filled is 4 g

Question 29

Accepted Answer

We haven't tried that, so we're not sure; this grade of asphalt is a very commonly used type for battery material coatings.

Question 30

Accepted Answer

The solid content varies between different products; please check the official website for specific parameters

Question 31

Accepted Answer

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

Question 32

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 33

Accepted Answer

Acetone degreasing → ultrasonic cleaning → water rinse → ultrasonic cleaning → acid wash (3 M HCl, ≤10 min ultrasonic) → water rinse.

Question 34

Accepted Answer

Yes, although some modification and optimization have been done to improve water stability, it still cannot use water as a solvent; NMP can be used. If water must be used, consider LATP.

Question 35

Accepted Answer

We tested it in a half-cell; theoretical gravimetric capacity >95 mAh/g

Question 36

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 37

Accepted Answer

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

Question 38

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 39

Accepted Answer

The 16mm separator typically matches a 16mm diameter Swagelok battery, which is a standard size configuration common in the laboratory.

Question 40

Accepted Answer

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

Question 41

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 42

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 43

Accepted Answer

Yes, it can be used; for the exact wiring, have the instructor contact the electrochemical workstation's technical support.

Question 44

Accepted Answer

This separator is the Celgard 2500 separator. We ourselves have not tested it the way the customer did. When we use it, we assemble cells directly and test cell performance.

Question 45

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 46

Accepted Answer

Yes, it is.

Question 47

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 48

Accepted Answer

LTO puddling typically does not use NMP, but instead uses deionized water (DI-water) as the solvent. This is because LTO materials are more suitable for aqueous systems and perform well in combination with water-soluble binders (such as CMC) and conductive agents (such as Super-P).

Question 49

Accepted Answer

In half-cells, all tested materials act as the cathode, while lithium metal is the anode. Charging corresponds to delithiation of the test material; discharging corresponds to lithiation.

Question 50

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 51

Accepted Answer

This is basically the same usage method as graphite anodes.

Question 52

Accepted Answer

For pure quasi-solid-state electrolytes, it is not recommended to add liquid electrolyte; you can achieve the target experimental results by modifying the formulation or testing conditions.

Question 53

Accepted Answer

The pellet’s strength and ionic conductivityhave small variations and have very little effect on battery performance, because during cell testing the current itself is very small.

Question 54

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 55

Accepted Answer

LiCl is hygroscopic in air; brief exposure can be reversed by reheating to remove crystalline water, but prolonged exposure to humid air will cause further decomposition. It is stable at room temperature; it has not been tested at high temperatures.

Question 56

Accepted Answer

The shelf life is one month from production. We can provide moisture, pH, particle size, and solids content. There is no quantitative data for lithium carbonate, but XRD can provide qualitative analysis.

Question 57

Accepted Answer

Possible causes include poor cell assembly stability, material degradation at high rates, or lithium dendrite formation causing micro short circuits.

Question 58

Accepted Answer

If the cathode range is 1.3 V–4 V, it is recommended that if graphite is used as the anode, the same electrochemical window of 1.3–4 V should be used.

Question 59

Accepted Answer

It is normal; it should be on the official website. This varies with different electrolytes; 90%–94% is all normal.

Question 60

Accepted Answer

There is no unified standard for this dilution ratio; you can adjust it according to your needs. This is relatively viscous, so to make sampling easier we usually take a portion and dilute it. Diluting to 7.5% or 5% is both acceptable.
