Question 15

Accepted Answer

A thickness of 8–10 μm is recommended.

Question 16

Accepted Answer

Not yet commercially produced.

Question 17

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 18

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 19

Accepted Answer

It is carbon-coated

Question 20

Accepted Answer

The melting point of aluminum foil is 660 °C.

Question 21

Accepted Answer

Currently commonly used are graphite, silicon–carbon, and lithium metal anodes. Silicon–carbon options use low silicon content to avoid excessive volume expansion. For lithium metal anodes, serious lithium dendrite growth must be considered in applications; lithium–indium alloy can be used to suppress the longitudinal growth of lithium dendrites to some extent.

Question 22

Accepted Answer

None at the moment.

Question 23

Accepted Answer

Nano sulfur

Question 24

Accepted Answer

They are all carbon-coated.

Question 25

Question 26

Accepted Answer

Hardness has not been tested. Check whether this item is listed in the material specification sheet

Question 27

Accepted Answer

NZSPO — this is a relatively mainstream and mature sodium-ion solid electrolyte technology at present. Regarding stability, it is stable across a voltage range of 0–4.5 V; it is stable at high voltage, and at low voltage it undergoes some reduction and valence change, but this does not greatly affect battery performance. If examining the mechanism microscopically, the low-voltage behavior may involve valence changes at the nanolayer level.

Question 28

Accepted Answer

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

Question 29

Accepted Answer

Cathodes are generally universal; it depends on system pairing and performance requirements. Currently commonly used are nickel–cobalt–manganese ternary (NCM) and lithium iron phosphate (LFP). LFP offers high safety and long cycle life but has moderate energy density and poor conductivity. NCM has higher energy density and better cycling stability and is an important development direction for solid-state battery cathodes, but high-nickel safety issues still need to be addressed. NCM811 for solid-state use requires coating treatment; there are existing niobate-coated NCM811 and borate-coated NCM811 options, which can be selected according to experimental needs.

Question 30

Accepted Answer

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

Question 31

Accepted Answer

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

Question 32

Accepted Answer

Key factors include: 1) use carbon-coated aluminum foil as current collector; 2) use CNT conductive slurry; 3) nano-sulfur is preferred over sublimed sulfur; 4) optimize slurry formulation; 5) apply light coating; 6) optimize electrolyte amount; 7) ensure correct material selection. Other improvements depend on lab-specific know-how.

Question 33

Accepted Answer

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

Question 34

Accepted Answer

About 25%.

Question 35

Accepted Answer

Question 37

Accepted Answer

Yes, it is multi-walled carbon nanotubes (MWCNT).

Question 38

Question 39

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 40

Accepted Answer

Not used as the primary electrolyte layer; it is generally used as an ion-conducting additive in the cathode. It can be directly paired with cathode materials such as LCO and NCM622, and the cathode material surface does not need coating.

Question 41
