Question 1

Accepted Answer

Acetone degreasing → ultrasonic cleaning → water rinse → ultrasonic cleaning → acid wash (3 M HCl, ≤10 min ultrasonic) → water rinse.

Question 2

Accepted Answer

Two common methods: 1) drop coating followed by drying, repeated in cycles; 2) roll the slurry into a film on glass, then press it onto the nickel foam.

Question 3

Accepted Answer

The diameter of the CR2032 positive shell of standard 304 material is 20mm.
The "3mm", "5mm", and "8mm" in the product list you see refer to the aperture of the hole in the center of the shell, not the diameter of the overall shell.

Question 4

Accepted Answer

For sodium batteries, it is recommended to use glass fiber / regular thick PE / alumina ceramic separators, or for all-solid-state use NZSPO ceramic sheets.

Question 5

Accepted Answer

The following configuration is recommended:

-Tear: The positive electrode is aluminum (Al) and the negative electrode is nickel (Ni). The size is recommended to be 2-3mm wide and 0.1-0.2mm thick, which can be cut into appropriate length according to the packaging method.
-Diaphragm: Wet PE diaphragm with a thickness of 9-12μm is recommended. If higher safety requirements are required, PE diaphragm with ceramic coating or PVDF coated diaphragm can be selected to improve thermal stability and interfacial bonding force.

This recommendation is based on current mainstream soft-pack battery manufacturing practices and incorporates information from the knowledge base on material properties and application scenarios to make reasonable inferences.

Question 6

Accepted Answer

You can use 523: SP:PVDF = 90:5:5

Question 7

Accepted Answer

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

Question 8

Accepted Answer

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

Question 9

Accepted Answer

Approaches include: reducing particle size; surface modification or coating; using high-performance conductive additives; reducing binder content while maintaining adhesion; improving mixing uniformity; optimizing current collectors; balancing compaction density; and optimizing electrolyte composition.

Question 10

Accepted Answer

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

Question 11

Accepted Answer

For polymer solid electrolyte button batteries with CR2025 battery case and positive electrode plate diameter of 12mm, it is recommended to use stainless steel discs with diameter of 12mm or 13mm as current collectors or gaskets, and the thickness is recommended to be between 0.2mm and 0.3mm to ensure good electrical contact and assembly compatibility. This recommendation is extrapolated from conventional button cell assembly practices.

Question 12

Accepted Answer

When assembling 2032 batteries, the thickness of nickel foam is generally recommended to be between 0.1mm and 0.3mm. This range not only ensures good electrical conductivity and structural support, but also does not occupy too much space inside the battery. However, the exact thickness will depend on the particular cell design and the dimensions of the other components. If you are not sure, you can start with 0.2mm thick foam nickel. This is an inference based on conventional applications.

Question 13

Accepted Answer

There are no specific gold-sputtering parameters because instruments vary, but there is an evaluation criterion: after gold plating, use a multimeter to test the resistance between any two points; values close to 1 ohm are ideal. The lower the vacuum during gold sputtering, the better. Continuous runs are not recommended because the plating equipment can become hot inside, and temperature will affect the evaporation/plating results.

Question 14

Accepted Answer

If the electrode sheet parameters are provided, it can be calculated.

Question 15

Accepted Answer

Use 5130 for high-nickel, use 900 for ordinary.

Question 16

Accepted Answer

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

Question 17

Accepted Answer

All are commercial cathode materials

Question 18

Accepted Answer

Single-crystal has a higher tap density and higher energy density; polycrystalline has better rate performance.

Question 19

Accepted Answer

Not at the moment, but we can procure them depending on customer demand. Would this require a nonwoven fabric separator?

Question 20

Accepted Answer

For our sodium nickel manganese iron oxide we use our own 12 4 2 separator. For the hard carbon capacity tests, our testing procedure is: rest 2 h, 0.2C DC to 0 V, 0.1C DC to 0 V, 0.01C DC to 0 V, 10 μA DC to 0 V, rest 3 min, 0.1C CC to 2 V.

Question 21

Accepted Answer

We don't have more cycling data updates for now; we will test and complete them later.

Question 22

Accepted Answer

Use high-nickel specific PVF

Question 23

Accepted Answer

This is a crystalline material, not a polymer, so the concept of molecular weight does not apply.

Question 24

Accepted Answer

We are very sorry. Our company mainly provides materials for the preparation of lithium-ion batteries; we are indeed not familiar with the specific preparation processes for battery manufacture. We apologize.

Question 25

Accepted Answer

Is there a charging plot on the official website? Generally, it must not exceed the normal tested electrochemical window. Look up the theoretical capacity on Baidu; I don’t know that either, but the actual capacity will definitely not reach the theoretical capacity.

Question 26

Accepted Answer

Single-crystal material, recommended formulation, 811: SP:PVDF (high-nickel anti-gel) = 90:5:5. Before testing the electrodes should be roll-pressed; recommended compaction ≥ 2.5

Question 27

Accepted Answer

The coating amount refers to the mass of surface modifier adsorbed on the surface of a given mass of powder, so the coating amount on each NCM811 is 0.6%.

Question 28

Accepted Answer

I confirmed with our engineering department that this inflection point is basically related to the electrolyte formulation; some formulations exhibit this inflection point while others do not. The specific technical details have not been fully researched by the engineering department yet.
