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

Question 4

Accepted Answer

Aluminum foil

Question 5

Accepted Answer

The slurry formulation for the coating is different

Question 6

Accepted Answer

The melting point of aluminum foil is 660 °C.

Question 7

Accepted Answer

At present, there are none.

Question 8

Accepted Answer

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

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

What is the purpose of the experiment? For preparing composite electrolyte membranes, choose the solvent based on the lithium salt used; you can consider DMAC   acetone. Of course, for specific solvent selection and usage, consult relevant literature for your experiment.

Question 11

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 12

Accepted Answer

A thickness of 8–10 μm is recommended.

Question 13

Accepted Answer

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

Question 14

Accepted Answer

Lithium–indium molar ratio 0.3:1.3, stoichiometric formula Li0.3In1.3 (or Li0.23In)

Question 15

Accepted Answer

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

Question 16

Accepted Answer

Electrospinning. The composition is pure PI; due to processing factors it is yellow. Not composite, just a yellow film.

Question 17

Accepted Answer

The intermediate layer electrolyte between it and the anode is generally LPSC (Li6PS5Cl is more stable, micron-sized; nanopowder reacts somewhat more with lithium metal). When assembling the two electrolyte layers apply a relatively large pressure, about 300 MPa, to ensure the electrolyte layers are highly dense; after adding the lithium anode the applied pressure should be very low to avoid instability at the LPSC//LiIn interface.

Question 18

Accepted Answer

Conductive carbon plus some binders

Question 19

Accepted Answer

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

Question 20

Accepted Answer

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

Question 21

Accepted Answer

The product information named "composite copper foil" is not directly provided in the knowledge base, but there is a "composite metal tape" (model: MA-EN-AN-0002) made of copper foil as the base and lithium foil, and its structure is coated with lithium foil on both sides or one side of the copper foil, such as "Li/Cu/Li" three-layer structure. Such products can be used for lithium battery anode materials, with specific composite functions. Therefore, if the "composite copper foil" referred to by the user is a metal-metal composite structure, the "composite metal tape" can be regarded as a related product. It is recommended to further confirm whether such a composite structure or a broader type of composite copper foil (e. g. copper-polymer composite) is required.

Question 22

Accepted Answer

It depends on the intended use. If it is for assembling pellet cells for electrical testing, the powder needs to be pressed into green bodies, then sintered into ceramics, and finally ground and polished for use. The green body can be made without adding other substances, or sintering aids, binders, etc. can be added. If used as a filler for polymer composite electrolytes, it can be added directly, or the particle size can be controlled according to experimental requirements before use.

Question 23

Accepted Answer

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

Question 24

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 25

Accepted Answer

Yes

Question 26

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 27

Accepted Answer

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

Question 28

Accepted Answer

When carrying out alkaline electrocatalysis, it is recommended to use carbon cloth with a model of "MA-EN-CU-0608", especially the version with a specification of "carbon cloth W1S1011 (hydrophobic type) 2520 cm/piece. This carbon cloth is treated with 10% PTFE and has a single-sided microporous layer, which can provide better hydrophobicity and larger surface area, which is conducive to catalyst loading and reactant transmission, thereby improving electrocatalytic performance. Although the thickness is slightly increased, this has little effect on the overall performance, but may bring additional benefits.

Question 29

Accepted Answer

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

Question 30

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 31

Accepted Answer

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

Question 32

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 33

Accepted Answer

No SEM images; Na3Zr2Si2PO12 powder shows primary particles of 3–5 µm under the electron microscope, and a particle size analyzer measures 10–40 µm. Depending on the specific use: if used as filler in composite polymers there is no need to sinter, but if making oxide electrolyte pellets you need to press the green body and sinter it into ceramic pellets.

Question 34

Accepted Answer

Silicon-carbon or SiO-carbon composite materials: no requirement on first-cycle efficiency; after 10 cycles efficiency is around >99.2%; stable cycling for 300 cycles with efficiency >99.8%; capacity retention about 80%; areal capacity 1–3 mAh cm-2; specific capacity 1200 mAh g-1. Do we have such materials? They want to customize electrodes.

Question 35

Accepted Answer

There is a layer of oxide film on the surface of lithium foil that is adhesive, so when lithium foils come into contact they will adhere to each other. Lithium foil is particularly sensitive to the atmosphere and should be stored in blue-capped glass bottles; before aliquoting it is necessary to vacuum-bake the glass bottles overnight and then place them in the glovebox for one day before subdividing.

Question 37

Accepted Answer

The electrolyte used for the test data of nickel-cobalt-aluminum NCA-S (model CU-EN-PL-8004) on the official website is: 1M LiPFis dissolved in EC:EMC (3:7) basic electrolyte, and does not contain FEC or other film-forming additives. If you need to test the electrolyte containing FEC and other additives, you need to contact customer service to customize. Thus, the currently published performance data reflect performance under standard additive-free conditions.

Question 38

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 39

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 40

Question 41

Accepted Answer

Strictly speaking, there is no "Cu negative electrode" having copper (Cu) as an active material ". Copper is only used as a negative current collector (such as copper foil, copper mesh) in lithium-ion batteries, and is used to conduct and support graphite and other negative materials that really participate in electrochemical reactions. The negative electrodes listed in the knowledge base are all carbon-based lithium intercalation materials (e. g., artificial graphite, CNT, etc.), and no product of copper metal as a negative electrode active material is provided. Users may misunderstand the distinction between "current collector" and "active material. This conclusion is based on the content of the knowledge base and the basic principles of the battery.

Question 42

Accepted Answer

The structure of the lithium–indium alloy foil is an indium sheet sandwiching lithium powder; alloying occurs under applied pressure during use. The negative electrode interface of the lithium–indium alloy does not deteriorate because indium reduces SEI formation and volume expansion, and the growth of lithium dendrites and lithium–indium dendrites differs: lithium dendrites grow vertically through the interface, while lithium–indium dendrites grow in a striped, lateral manner, making them denser and more uniform than lithium dendrites.

Question 43

Accepted Answer

Yes, conductive carbon black (Super P Li) can be used in the production of conductive carbon paste, especially for scenarios that require good conductivity and dispersion.

Question 44

Accepted Answer

The molar ratio of Li to In in the lithium indium alloy sheet was 0.3:1.3.

Question 45

Accepted Answer

The copper mesh suitable for TEM sample preparation is a product with MA-EN-CU-0018 models, especially its specifications are "wire diameter 28um,400 mesh, phosphor copper" or "wire diameter 50um,200 mesh, red copper" and other versions. Because its specifications are consistent with TEM carrier mesh commonly used in scientific research and are purchased and used by many scientific research institutions, it is inferred that it is suitable for electron microscope sample preparation.

Question 46

Accepted Answer

"Micro-grid copper mesh for beat transmission" refers to a special carrier mesh used for transmission electron microscope (TEM) sample support. It usually consists of a fine wire copper mesh (such as 200 mesh or 400 mesh) as a mechanical support frame, and the surface is covered with a carbon film with a porous structure (I. e., "micro-grid"). These micro-holes allow the electron beam to pass through, and at the same time, the sample particles can be attached to the hole edge or membrane, which is convenient for high-resolution imaging.

Although the "copper mesh" (model MA-EN-CU-0018) in the knowledge base is mainly used for battery current collectors, its high-precision specifications (e. g. 400 mesh, 0.04mm mesh) indicate its potential as a micro-grid copper mesh substrate, especially in experimental material application scenarios. Therefore, it can be inferred that this kind of products can be used for TEM sample preparation after further processing (such as carbon plating micro-gate film).

Question 47

Accepted Answer

In "ceramic separator 12 2ccs 2pcs", "pcs" refers to a polymer coating layer (such as PVDF coating), especially a functional polymer layer further coated on the basis of ceramic coating (CCS). According to the knowledge base description, "PVDF is coated on the surface of ceramic particles with a thickness of ~ 2um", so "PCS" can be understood as an abbreviation for Polymer-Coated Slurry or PVDF Composite Slurry. The structure improves the thermal stability through the ceramic layer, and then enhances the adhesion between the positive electrode and the separator through the PVDF layer, which improves the cycle performance and mechanical strength of the battery.

Question 48

Accepted Answer

According to the knowledge base, a lithium nitride (LiLPN) layer is indeed formed on the surface of the lithium sheet. This is one of the products produced by the reaction of the surface of metallic lithium with nitrogen or moisture in the air when it is exposed to the air. It can therefore be concluded that the surface of the lithium sheet is usually covered with a layer of lithium nitride.

Question 49

Accepted Answer

28BC GDL carbon paper (SGL SIGRACET gas diffusion layer, model MA-EN-CU-0019) is recommended. The carbon paper has a microporous layer (MPL) with PTFE hydrophobic treatment, and the water contact angle is> 130 °, which can effectively regulate the gas-liquid transmission, and is stable in the electrochemical reduction of carbon dioxide, and has been clearly used in this field. In contrast, other hydrophobic carbon papers do not provide adequate technical support or application validation.

Question 50

Accepted Answer

The carbon-coated electrode is indeed a metal foil (such as aluminum foil, copper foil) coated with a layer of carbon material (such as conductive carbon black). According to the information provided, the common carbon-coated electrode is single-sided carbon coating, for example, the product MA-EN-CU-0004 is single-sided coating. Although there may be double-sided carbon coating, it should be specifically stated that conventional delivery and use are mainly single-sided. Therefore, in general, "carbon coated" refers to a single side coated carbon.

Question 51

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 52

Accepted Answer

According to the available information, the "high-foot storage box" (model MA-EN-CU-0035) is a transparent plastic product, but its material and temperature resistance are not provided in the knowledge base. Based on the inference of common plastic materials, its short-term temperature resistance may be between 80-100 ℃, and long-term use is recommended not to exceed 60 ℃. If it needs to be used in high temperature environment (such as oven), the material should be further confirmed or a special container clearly marked with high temperature resistance should be selected. Current information is not sufficient to support a higher temperature judgment.

Question 53

Accepted Answer

Yes, the tab adhesive can be used to attach to a copper (Cu) current collector, but it is usually used on copper tape that has undergone surface treatment (such as nickel plating). This structure can effectively prevent copper oxidation and ensure good adhesion with the tab glue. Under the appropriate heat sealing process conditions (temperature, pressure, time), with the special ear glue material, it can completely ensure the air tightness after heat sealing with the aluminum plastic film. This conclusion is based on the Cu/Ni tab products provided by GSEM and its complete surface treatment and sealing technology system.

Question 54

Accepted Answer

Yes, the sodium battery dry cell (model CU-PO-S1-1001) on the official website has cycle performance. Although the specific number of cycles is not directly marked, it can be seen from the information provided by the component capacity process, the working voltage window and the clear prompt "the cycle test process will become loose and fixtures are required" that the product is specially designed to support cycle performance research. After filling and packaging, users can perform cycle life testing under controlled pressure conditions, which is suitable for pilot test verification and electrochemical performance evaluation.
