Question 1

Accepted Answer

Silicon oxide (1400) and silicon oxide (1600): both of these materials have a carbon coating

Question 2

Accepted Answer

Although the knowledge base does not provide relevant information, according to the research progress of magnesium batteries, the following electrolyte and solvent combinations are recommended for magnesium battery systems:

-Solvents: Ether solvents are preferred, such:
-Tetrahydrofuran (THF)
-1,2-Dimethoxyethane (DME)
-Triglyme (Triglyme)

-Electrolyte system:
1. APC electrolyte: composed of MgCl₂, AlCl3 and NaCl, soluble in THF, has good reversibility of magnesium deposition (but contains chlorine, which may corrode the current collector).
2. HMDS-based electrolyte: such as Mg(HMDS)/AlCl3/DME, excellent performance but higher cost.
3. Borate or magnesium amine systems: such as Mg (BHalready) or Mg(TFSI) in DME, are relatively mild and do not contain chlorine, suitable for research applications.
4. Commercialization tendency system: Some new non-corrosive magnesium electrolytes are being developed, such as DME solutions based on magnesium bis(fluorosulfonyl)imide (Mg(FSI)), with additives to improve stability.

Recommendation: In laboratory studies, the exploration can be started from the dissolution of Mg(TFSI) in DME or THF, paying attention to strict water removal and inert atmosphere operation, and evaluating its cycle performance and interface stability in button batteries.

Question 3

Accepted Answer

It is not a polymer. It is a sintered ceramic oxide and can be used directly.

Question 4

Accepted Answer

The current maximum achievable is 4.3 mAh/cm2

Question 5

Accepted Answer

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

Question 6

Accepted Answer

Yes

Question 7

Accepted Answer

No coating

Question 8

Accepted Answer

At present, there are none.

Question 9

Accepted Answer

Store in a cool, dry place, sealed.

Question 10

Accepted Answer

It's the molar ratio.

Question 11

Accepted Answer

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

Question 12

Accepted Answer

Demand for LLZO-coated separators is currently low; they require customization. The minimum order quantity for customization is 5,000 m².

Question 13

Accepted Answer

This is rGO

Question 14

Accepted Answer

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

Question 15

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 16

Accepted Answer

Common systems: PTFE (water-based, mainly for aqueous supercapacitors); PVDF (NMP, oxide cathodes); CMC SBR (carbon-based anodes); PAALi (silicon–carbon systems).

Question 17

Accepted Answer

This separator is composed of a PE base film, an alumina coating, and a LATP oxide electrolyte coating, and does not contain any lithium salts.

Question 18

Accepted Answer

If lithium salt is added, evaporation must be done in a glovebox; lithium salts must not contact water, as they are hygroscopic and deliquescent.

Question 19

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 20

Accepted Answer

Oxide electrolyte slurries are currently available for sale: LATP, LLZO, and LLZNTO slurries. Solid content can be customized from 15% to 40%, and there are minimum order quantity requirements. For details, please refer to the official website.

Question 21

Accepted Answer

Store sealed after use in a dry environment. Some oxide solid electrolytes are slightly sensitive to moisture, but short-term exposure has no effect.

Question 22

Accepted Answer

Yes, we need requirements for particle size, solids content, and solvent. Minimum order quantity is 5 kg, and the shelf life is one month.

Question 23

Accepted Answer

There are currently no all-solid-state films; oxide sheet separators are available. Finished sulfide pure solid electrolyte films are under development and will be launched soon—stay tuned.

Question 24

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 25

Accepted Answer

All finished ternary materials (111 523 622 811 series 9xx) are coated; the coating is an oxide. Specific compositions vary by manufacturer and are strictly confidential, not disclosed externally

Question 26

Accepted Answer

Polyethylene oxide (PEO) is a polymeric substrate that needs to be dissolved in a solvent, have lithium salt added, and then be dried into a film. It cannot be directly pressed from powder.

Question 27

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 28

Accepted Answer

PEO itself is very stable in air, but it is generally used mixed with lithium salts, which are hygroscopic and absorb water; LATP is stable in air.

Question 29

Accepted Answer

Using LLZO would be better; for electrolyte pellets use LLZTO. Relatively speaking, LLZO is somewhat more stable against lithium metal than LAGP or LATP.

Question 30

Accepted Answer

Oxide electrolyte ceramic sheets are cold-pressed and sintered, not simply molded by compacting powder; in addition, especially thin sheets or those with larger areas are prepared by tape casting.

Question 31

Accepted Answer

LAGP, LATP, and NZSPO are water-stable. LLZO and LLTO are slightly sensitive to moisture; they can be exposed to air for short periods in a low-humidity room, but prolonged exposure will have some effect.

Question 32

Accepted Answer

Under normal circumstances, poly(ethylene oxide) (PEO) will become a colorless or slightly yellow liquid when dissolved; the choice of solvent also affects the color.

Question 33

Accepted Answer

The oxide electrolyte powders we currently sell are LATP, LAGP, LLZO, LLTO, LALZO, LLZNTO, NZSPO, and LZSPO; the oxide ceramic sheets available are LATP, LAGP, LLZTO, and NZSPO. Standard thickness is 1 mm, diameters range from 10 to 15 mm, and custom specifications can be discussed with customer service.

Question 34

Accepted Answer

Among the different types of electrolytes, oxide solid electrolytes have better resistance to water and oxygen. In particular, LATP, LAGP, and NZSPO have high water stability; LLZO, LLZTO, and LLTO are secondary. Therefore many manufacturers now perform water-resistant modification on LLZO.

Question 35

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 36

Accepted Answer

Conventional cathode and anode sheets and ceramic sheets form the battery, and there are contact interfaces that require adding a small amount of electrolyte to wet the interfaces. However, if the ceramic sheet surface is treated together with the cathode and anode material processes so that the electrode materials make better contact with the electrolyte sheet, electrolyte wetting of the interface is not necessary.
