Question 1

Accepted Answer

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

Question 2

Accepted Answer

It's single-sided

Question 3

Accepted Answer

Our graphite electrode test results are on the official website

Question 4

Accepted Answer

The amount of electrolyte filled is 4 g

Question 5

Accepted Answer

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

Question 6

Accepted Answer

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

Question 7

Accepted Answer

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

Question 8

Accepted Answer

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

Question 9

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 10

Accepted Answer

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

Question 11

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 12

Accepted Answer

Yes, it is.

Question 13

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 14

Accepted Answer

This is basically the same usage method as graphite anodes.

Question 15

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 16

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 17

Accepted Answer

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

Question 18

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 19

Accepted Answer

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

Question 20

Accepted Answer

For 811 cathode, the specific capacity is roughly just over 180 mAh/g; this is considered normal.

Question 21

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 22

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.

Question 23

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 24

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 25

Accepted Answer

Must be cut in a glove box. After cutting, it should be rolled using a PTFE or glass rod. For potassium batteries, the metal is often rolled into thin sheets after forming small spheres. Rolling can be done directly on spacers, which then serve as carriers during coin cell assembly.

Question 26

Accepted Answer

There is essentially no noticeable difference between the two; the main distinction is in self-discharge, but it is very small — the latter has about 0.005 mV/hour lower self-discharge.

Question 27

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 28

Accepted Answer

Dissolve the CMC first, then add the conductive agent graphite; after dispersing well, add the SBR last (we introduced this in the article on anode stirring on our public account)

Question 29

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 30

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 31

Accepted Answer

Thinking process:

1. The problem focuses on the choice of binder for "high expansion anode materials such as silicon carbon", with special reference to "recommended use of modified PAA or PAA/SBR composite system" and "PAA or CNT enhanced network structure". It is necessary to judge whether these recommendations are reasonable in combination with the content of the knowledge base, and to carry out integration analysis.

2. Challenges in the Knowledge Base on Silicon Carbon Anodes:
-Silicon expands up to 300% in volume during charge and discharge, resulting in particle breakage, repeated SEI generation, electrical contact failure, and poor cycle performance.
-The internal stress of the negative pole piece is large, and the traditional CMC/SBR bonding force is not enough to maintain structural stability.

3. Information about PAA (polyacrylic acid):
-The document "Binder property vs. cell performance" clearly points out: PAA has a high Young's modulus and strong hydrogen bonding, which can provide

Question 32

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 33

Accepted Answer

For oxide electrolyte pellets assembled into button cells, common dimensions are 10–16 mm diameter and 1 mm thickness, matching CR2032 cases. Ceramic pellets are quite hard but brittle; the pressure needed when crimping a button cell must be determined experimentally. During assembly the parts must be aligned, all contact surfaces flat and free of debris, and pressure applied slowly. Assembly skill is important; you cannot guarantee the pellet won’t crack regardless of how you press.

Question 34

Accepted Answer

The "AI-plated battery case" you mentioned may have errors in expression or conceptual confusion. According to the available information, no "AI plating" technique is currently applied to battery cases. But we can speculate that what you might want to know is one of the following related technologies:

Aluminum plating (Aluminum Coating): In some battery designs, especially the soft pack battery (Pouch Cell), a composite film with an aluminum layer is used as a shell material (such as aluminum plastic film). This aluminum layer acts as a conductive, shielding and structural support, not a "AI" (artificial intelligence).

2. Surface treatment technology: The battery shell (such as steel shell or aluminum shell) is often surface coating treatment, such as zinc plating, nickel plating, etc., to enhance corrosion resistance, conductivity and welding performance. These are traditional metal surface treatment processes.

3. Application of AI in battery manufacturing: Although it is not "plating AI", artificial intelligence (AI) is indeed widely used in the battery manufacturing process, such:
-Quality inspection (judging battery appearance defects through image recognition)
-Optimization of process parameters (e. g. intelligent control of stirring, coating and rolling processes)
-Fault prediction and sorting (e. g. identification of potential failure risks through data analysis)

To sum up, "plating the AI battery case" is not a practical technology. You may be mistaking "Al plating" (aluminum plating) as "AI plating", or referring to the intelligent application of AI technology in the manufacture of battery cases. Please confirm the specific direction of your question in order to get a more accurate answer.
