Question 1

Accepted Answer

Yes

Question 2

Question 3

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 4

Accepted Answer

This is basically the same usage method as graphite anodes.

Question 5

Accepted Answer

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

Question 6

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 7

Accepted Answer

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

Question 8

Accepted Answer

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

Question 9

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 10

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 11

Accepted Answer

Nano sulfur

Question 12

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 13

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 14

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 15

Accepted Answer

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

Question 16

Accepted Answer

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

Question 17

Accepted Answer

For sodium batteries, separators generally use glass fiber separators GF-D, or you can directly use lithium battery separators.

Question 18

Accepted Answer

We haven't tried that and aren't sure; this asphalt is a very commonly used grade for coating battery materials.

Question 19

Accepted Answer

Sulfide and halide electrolyte systems can use lithium-indium as the negative electrode, but oxide systems are more suitable for graphite and low-silicon negative electrodes.

Question 20

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 21

Accepted Answer

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

Question 22

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 23

Accepted Answer

From our current packaging results, a packaging thickness of about 2.6–2.7 mm works better

Question 24

Accepted Answer

Both are coated; they are just different models of LiFePO4. D-3
