Question 1

Accepted Answer

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

Question 2

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 3

Accepted Answer

This is basically the same usage method as graphite anodes.

Question 4

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 5

Accepted Answer

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

Question 6

Accepted Answer

Yes

Question 7

Accepted Answer

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

Question 8

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 9

Accepted Answer

Punched sheet weight * active material ratio (96%) = weight of the active material

Question 10

Accepted Answer

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

Question 11

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 12

Accepted Answer

Use a standard 2032 case and follow the same assembly procedure as for liquid cells. The only caution is to use a manual crimper to slowly apply pressure when sealing; it is best not to use an electric crimper. Crimp until the claw walls around the perimeter (the positive case covering the edge of the negative case) are slightly deformed — it is not necessary to fully encase them as with liquid cells. The pressure is about 500 MPa, adjustable according to the actual equipment used; mainly judge by the extent of deformation of the case edge. Excessive pressure can cause breakage. The assembled parts must be aligned, pressure applied evenly, and done slowly.

Question 13

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 14

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 15

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 16

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 17

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 18

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 19

Accepted Answer

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

Question 20

Accepted Answer

Yes

Question 21

Accepted Answer

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

Question 22

Accepted Answer

The main difference between CR2032, CR2016, and CR2025 is the physical size, especially the thickness (3.2mm, 1.6mm, and 2.5mm, respectively), although they are similar in diameter (about 20mm). This size difference determines that they are suitable for different battery structure design or instrument requirements. In addition, these models can be matched with gaskets and shrapnel of different specifications (such as 15.5 × 0.5mm, 15.8 × 1.0mm, etc.), and can be used for button battery assembly in scientific research experiments. Due to the different heights, it is necessary to pay attention to whether it will affect the compaction or sealing of the electrode when used interchangeably, so it is not recommended to replace it at will. Inference: If the experiment has strict control over the battery volume or pressure, the corresponding model should be selected in strict accordance with the design.

Question 23

Accepted Answer

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

Question 24

Accepted Answer

Yes, their crystal structures are the same.

Question 25

Accepted Answer

Different manufacturers vary; recommend the customer use D-3

Question 26

Accepted Answer

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

Question 27

Accepted Answer

The slurry is generally used for coating separators or added into the cathode as an ion-conducting additive. Electrolyte pellets can be assembled into button cells, pouch cells, or used for research into novel batteries such as seawater batteries.

Question 28

Accepted Answer

It's single-sided

Question 29

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 30

Accepted Answer

They can be assembled into button cells or mold cells; generally button cells are used, because molds require higher dimensional accuracy of the electrolyte sheets, and the assembly process must avoid short circuits or uneven pressure that could cause the sheet to crack.

Question 31

Accepted Answer

Our graphite electrode test results are on the official website

Question 32

Accepted Answer

Nano sulfur

Question 33

Accepted Answer

Typically caused by assembly issues. Verification can be done using standard commercial materials. Factors include slurry uniformity, separator thickness, electrolyte wetting, rest time, and electrode consistency.

Question 34

Accepted Answer

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

Question 35

Accepted Answer

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

Question 36

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 37

Accepted Answer

The amount of electrolyte filled is 4 g

Question 38

Accepted Answer

After rolling, the electrodes will all exhibit this curling when electrolyte is dropped on them. Suggested improvements: 1) When baking the punched electrodes, press them flat with a plate while baking; 2) Optimize the assembly method. We usually place the electrode on the spacer, drop the electrolyte, and then cover it with the separator, which also makes subsequent assembly easier.

Question 39

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 40

Accepted Answer

Carbon cloth cannot be used directly as a lithium battery anode; it has no capacity. Anodes generally use graphite, hard carbon, silicon-carbon, etc.

Question 41

Accepted Answer

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

Question 42

Accepted Answer

Yes. Strict moisture control is required, except for electrolytes used in aqueous battery systems.
