Aluminum foil

Question 9

Accepted Answer

A thickness of 8–10 μm is recommended.

Question 10

Accepted Answer

For button batteries that require high temperature resistance of more than 180 °, it is recommended to use a button battery shell made of 316L material. This material has good high temperature resistance and can meet the requirements. This is based on the general characteristics of stainless steel 316L inferred results.

Question 11

Accepted Answer

According to the conventional performance of 316L stainless steel, 316L material buckle shell four-piece set can theoretically withstand 200 degrees high temperature, but the specific performance may need to refer to the product specification or further test verification. This conclusion is an inference based on material properties.

Question 12

Accepted Answer

The main difference between CR2025 and CR2032 is the material (CR2025 is 316L stainless steel, CR2032 is 304 stainless steel), the selection range of shrapnel types and specifications, and CR2032 has stronger customization capabilities. This suggests that they may be aimed at different battery designs and technical needs.

Question 13

Accepted Answer

The slurry formulation for the coating is different

Question 14

Accepted Answer

[Powder Pressing Method] Dry powder is placed into a steel die and pressed at 250–500 MPa to form a green body, then sintered in a muffle furnace in air atmosphere at about 900°C for 3–24 hours. After sintering and cooling, the ceramic discs are ground. The green body pressing may include a binder or not, and may include a sintering aid or not. Binders used include PVA, PVB, etc.; sintering aids include boron oxide, lithium borate, and similar. Note that if a binder is added, the sintering must be staged to allow binder burn-out; otherwise the carbon content will be too high.

Question 15

Accepted Answer

Conductive carbon plus some binders

Question 16

Accepted Answer

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

Question 17

Accepted Answer

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

Question 18

Accepted Answer

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

Question 19

Accepted Answer

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

Question 20

Accepted Answer

Yes

Question 21

Accepted Answer

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

Question 22

Accepted Answer

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

Question 23

Accepted Answer

Yes, stainless steel mesh can be used as a current collector for dry-process electrodes, especially in aqueous batteries or dry-process preparation processes that require porosity of the current collector. Its network structure is conducive to dry powder adhesion and electronic conduction, and high mechanical strength, suitable for roll forming. But should pay attention to its chemical stability limitations-recommended for dilute sulfuric acid and other mild electrolyte environment, 316L stainless steel is better than 304 stainless steel. In high voltage or strong alkaline system should be used with caution to avoid corrosion.

Question 24

Accepted Answer

It won't. An aluminum or nickel-plated buckle case will not be more resistant to low temperatures than a 304 or 316 stainless steel buckle case, but may be more risky.

The detailed explanation is as follows:

-304 and 316L stainless steel are austenitic steels with excellent low temperature toughness and can be used safely at -196 ℃. They are ideal metal shell materials in low temperature environments.
-The nickel plating may become brittle at low temperatures, there is a risk of flaking, and nickel ions may contaminate the battery system.
-The aluminum plating layer is not only poor in thermal matching and easy to delaminate, but also unstable (easy to alloy) in the lithium battery environment, which is totally unsuitable as the material of the buckle shell, especially on the negative side.

Therefore, from the point of view of safety, stability and practicality, the original stainless steel (304/316L) is the most suitable material for low-temperature experiments, without the need to improve the coating. Existing products have been able to meet the vast majority of low-temperature electrochemical testing needs.

Question 25

Accepted Answer

"Aqueous electrolyte resistance" refers to the ability of a material to remain chemically and electrochemically stable in an aqueous environment and not to be corroded or degraded. Not all conventional battery materials have this property. For example, 304 stainless steel is not resistant to aqueous electrolytes and is prone to pitting; while titanium, 316L stainless steel, PP/PE diaphragm, PVDF, PTFE and aluminum-plastic film have good tolerance and are suitable for aqueous battery systems. When designing water-based zinc batteries or other water-based energy storage devices, proven "water-based electrolyte" materials must be selected to ensure long-term cycle stability and safety.

Question 26

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 27

Question 28

Accepted Answer

304 stainless steel has limited corrosion resistance in aqueous electrolytes, especially when it contains chloride ions or pH is unstable, it is prone to pitting and electrochemical corrosion, so it is not recommended to be directly used in the key components of aqueous zinc ion batteries (such as current collectors, tabs or shells). If metal structures must be used, preference should be given to the more corrosion-resistant 316L stainless steel or coating protection measures. Ideally, aqueous zinc batteries should use titanium, carbon materials or plastic packaging systems to improve stability and cycle life.

Question 29

Accepted Answer

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

Question 30

Accepted Answer

From the point of view of power deduction, CR2025 button battery case is recommended for NCM system with positive electrode 60-70μm, diaphragm 20μm and negative electrode 40-60μm (including graphite doped silicon carbon), especially the 316L stainless steel version mentioned in the knowledge base. This model has enough internal space to accommodate the electrode assembly and relieve the volume expansion stress of the silicon carbon negative electrode. At the same time, it has excellent corrosion resistance and sealing performance, which is very suitable for the electrochemical performance test and evaluation of this kind of material system.

Question 31

Accepted Answer

The lithium electrolyte (KLD-LP175) contains LiPF6, and may be decomposed in the presence of a trace amount of moisture to generate HF, which is corrosive to a certain extent. Although the free acid content is controlled at a low level (≤ 50 ppm), it may still react slowly with metal materials such as iron and steel, especially under humid or long-term contact conditions. Therefore, it is not recommended to use containers or tools made of iron or steel in direct contact with the electrolyte. It is recommended to use corrosion-resistant materials (such as plastic, glass or inert treated materials such as stainless steel 316L) for handling and storage.

Question 32

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 33

Accepted Answer

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

Question 34

Accepted Answer

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

Question 35

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 36

Accepted Answer

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

Question 37

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 38

Accepted Answer

Gasket specifications suitable for 2340 models may include: nylon layer thickness 15μm, aluminum layer thickness 35μm,PP layer thickness 30μm, total thickness 86μm composite material. This conclusion is extrapolated based on the Foil specification of Showa 86um Black Matte Packing mentioned in the knowledge base, assuming similar material requirements for model 2340 devices.
