The current maximum achievable is 4.3 mAh/cm2

Question 3

Accepted Answer

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

Question 4

Accepted Answer

Yes

Question 5

Accepted Answer

No coating

Question 6

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 7

Accepted Answer

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

Question 8

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 9

Accepted Answer

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

Question 10

Accepted Answer

All are commercial cathode materials

Question 11

Accepted Answer

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

Question 12

Accepted Answer

Aluminum foil

Question 13

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 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

Nano sulfur

Question 16

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 17

Accepted Answer

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

Question 18

Accepted Answer

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

Question 19

Accepted Answer

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

Question 20

Accepted Answer

Pure sulfur

Question 21

Accepted Answer

Use 5130 for high-nickel, use 900 for ordinary.

Question 22

Accepted Answer

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

Question 23

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 24

Accepted Answer

Graphite

Question 25

Accepted Answer

You can use 523: SP:PVDF = 90:5:5

Question 26

Accepted Answer

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

Question 27

Accepted Answer

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

Question 28

Accepted Answer

We don't have data on this anode material, but based on graphite, the electrode sheet color varies at different states of charge. You can ask the customer to perform an experiment: charge to different states, then disassemble the cell and observe

Question 29

Accepted Answer

It has not been lithiated; it is just a regular graphite anode electrode.

Question 30

Accepted Answer

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

Question 31

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 32

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 33

Accepted Answer

We don't have more cycling data updates for now; we will test and complete them later.

Question 34

Accepted Answer

Cathodes are generally universal; it depends on system pairing and performance requirements. Currently commonly used are nickel–cobalt–manganese ternary (NCM) and lithium iron phosphate (LFP). LFP offers high safety and long cycle life but has moderate energy density and poor conductivity. NCM has higher energy density and better cycling stability and is an important development direction for solid-state battery cathodes, but high-nickel safety issues still need to be addressed. NCM811 for solid-state use requires coating treatment; there are existing niobate-coated NCM811 and borate-coated NCM811 options, which can be selected according to experimental needs.

Question 35

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 36

Accepted Answer

Our graphite electrode test results are on the official website

Question 37

Accepted Answer

SBR CMC

Question 38

Accepted Answer

Haven't tested it, but judging from the structural formula, the material's electrochemical stability should be fine.

Question 39

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 40

Accepted Answer

Use metallic lithium as the reference electrode

Question 41

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 42

Accepted Answer

Compared with polycrystalline cathode materials, single-crystal cathodes have somewhat poorer conductivity; you need to increase the conductive additive content based on their standard formulation. Alternatively, if you do not want to raise the total conductive additive content, you can replace part of the conductive carbon with CNTs.

Question 43

Accepted Answer

MnO2:PVDF:Super P = 94:3:3 is the formulation, and then optimize based on that.

Question 44

Accepted Answer

Single-crystal has a higher tap density and higher energy density; polycrystalline has better rate performance.

Question 45

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 46

Accepted Answer

Yes, LATP can be in contact with the cathode material. According to the knowledge base information, LATP is chemically stable to common cathode materials (such as NCM811, LFP, LCO), so it can be directly contacted with the cathode. However, on the negative electrode side, since LATP is unstable to lithium metal (titanium is easily reduced), additional measures (such as interface treatment or use of other negative electrode materials) are required.

Question 47

Accepted Answer

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

Question 48

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 49

Accepted Answer

The electrolyte KLD-H3067 can be charged and discharged at a minimum of about -30 ℃, and its recommended operating temperature range is -30 ℃ to 60 ℃, which may be extended to -40 ℃ to 70 ℃ in the optimized system.
The electrolyte is suitable for the following electrode materials:
-Positive electrode: NCM523, NCM622, NCM811, lithium cobaltate (LCO), lithium manganate (LMO) and other conventional ternary or oxide positive electrodes;
-Negative electrode: artificial graphite, natural graphite, silicon carbon composite materials and other mainstream negative electrode system.

Because it contains FEC film-forming additives, it is particularly beneficial to improve the low-temperature performance and cycle stability of graphite and silicon carbon negative electrodes, and is a basic functional electrolyte suitable for wide-temperature lithium-ion batteries.

Question 50

Accepted Answer

According to the clear guidance of the existing knowledge base, there is no single designation of "which" positive pole piece, but a recommended list is given. Therefore, the positive pole pieces that can be used include but are not limited to NCM811, LFP and LCO. In practical applications, you can choose from these compatible materials according to the specific requirements of battery design (such as the pursuit of energy density or safety).

Question 51

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 52

Accepted Answer

The ionic conductivity of the solid electrolyte can be tested directly on pressed pellets. When assembling an all-solid-state battery, it is often mixed with the cathode in a certain ratio to form a composite cathode and is not used directly as the electrolyte layer. The electrolyte layer commonly uses LPSC, the anode uses a lithium–indium alloy, and a mold cell is assembled.

Question 53

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 54

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 55

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 56

Accepted Answer

We are very sorry — we really don't know. These two materials are both produced by companies that rank among the top three in the industry; they do not disclose any production technical details externally.

Question 57

Accepted Answer

KS-6 itself is a conductive agent and is generally not used as a negative electrode active material. If it were to be used as a negative electrode active material, it should not be necessary to add Super P.

Question 58

Accepted Answer

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

Question 59

Accepted Answer

It can be used after drying, but there may be some effects: capacity might decrease and internal resistance may increase.

Question 60

Accepted Answer

Yes

Question 61

Accepted Answer

The lithium foil diameter is determined by the diameter of the electrode and the separator. The lithium foil diameter should be larger than the electrode diameter and smaller than the separator diameter. The greater the differences among these three diameters, the easier assembly and better contact for the coin cell. The internal total thickness of a 2032 coin cell case needs to reach about 3.2 mm; any shortfall can be filled with shims. The main thing is to choose the diameter.

Question 62

Accepted Answer

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

Question 63

Accepted Answer

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

Question 64

Accepted Answer

At present, there are none.
