Question 1

Accepted Answer

Yes

Question 2

Accepted Answer

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

Question 3

Accepted Answer

Recommend he buy an adjustable one so he can apply as much as he wants

Question 4

Accepted Answer

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

Question 5

Question 6

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 7

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 8

Accepted Answer

Seal unused portions in a self-sealing bag; dispose of spent solid waste the same way as lithium metal.

Question 9

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 10

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 11

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 12

Accepted Answer

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

Question 13

Accepted Answer

It's single-sided

Question 14

Accepted Answer

Our graphite electrode test results are on the official website

Question 15

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 16

Accepted Answer

The amount of electrolyte filled is 4 g

Question 17

Accepted Answer

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

Question 18

Accepted Answer

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

Question 19

Accepted Answer

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

Question 20

Accepted Answer

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

Question 21

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 22

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 23

Accepted Answer

Yes, it is.

Question 24

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 25

Accepted Answer

This is basically the same usage method as graphite anodes.

Question 26

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 27

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 28

Accepted Answer

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

Question 29

Accepted Answer

In the tab welding process, tab adhesive is used to insulate and secure the tab relative to other parts. Currently, the domestic market uses white adhesive, black adhesive, yellow adhesive, and single-layer adhesive for tabs. A comparative analysis of these adhesives is as follows: Black adhesive’s functional layer and PP layer are composed of different substances, creating many interfaces; after electrolyte immersion it tends to delaminate, and the black adhesive’s PP layer contains three substances with different melting points: black pigment: 66°C, PE 105°C, PP 137°C, making the interface more unstable. Yellow adhesive’s functional layer has a melting point close to 300°C, so it is easier to operate during heat sealing. Its middle functional layer has replaced the original polybutylene terephthalate with a nonwoven fiber layer, resulting in better interfacial fusion than black adhesive, but it still cannot solve the problem of complete fusion between different materials. Due to the PP layer technology in yellow adhesive, it becomes abnormally hard after heat sealing and loses flexibility; during cell packaging and later processing (tabbing to nickel, adding plates), this can cause the tab adhesive and tab metal to break, leading to electrolyte leakage and gas swelling in the cell. White adhesive uses materials of the same type (PP class) for its three functional layers, so it still maintains high flexibility after heat sealing. White adhesive is produced by co-extruding three layers of PP materials with different functions. Its functional layer has a wide heat-sealing temperature range of 150–180°C, slightly lower than the cell packaging temperature (180–220°C), which can effectively prevent edge short circuits and increases the operable temperature range during cell packaging. Its broader heat-seal temperature ensures fusion with the aluminum-plastic film, and the clear temperature differences among the three PP layers improve packaging operability and increase cell production yield. Single-layer white adhesive is similar to the early inner layer of aluminum-plastic film; because it has only one melting point, if the heat-seal temperature exceeds that melting point it easily causes complete melting short circuits, while insufficient heat-seal temperature leads to softening, which prevents complete melting and polymerization with the CPP layer of the aluminum-plastic film. In the use of tab adhesive, special attention is generally paid to the adhesion between the tab adhesive and the aluminum-plastic film, liquid resistance, the sealing degree with the metal strip, and the tightness of edge fusion and corner sealing. These factors are closely related not only to the properties of the tab adhesive but also to metal strip anticorrosion and wetting treatments, the tab manufacturing process, and the cell sealing process. Therefore, the most suitable tab adhesive should be chosen according to actual process requirements.

Question 30

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.
