Question 38

Question 39

Accepted Answer

The customer can make the slurry themselves; we cannot do it at present.

Question 40

Accepted Answer

Causes include high surface area materials absorbing binder, low solid content, fast solvent evaporation, insufficient binder, and excessive coating thickness. Solutions involve formulation and process optimization.

Question 41

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 42

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.

Question 43

Accepted Answer

Possible reasons include: 1) air bubbles in slurry (vacuum degassing recommended); 2) foreign particles introduced during mixing or coating; 3) foreign materials acting as foaming agents; 4) insufficient slurry dispersion.

Question 44

Accepted Answer

It's because of conductivity issues. Cathode materials themselves have poor conductivity, so they are generally coated.

Question 45

Accepted Answer

Yes, it is.

Question 46

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 47

Accepted Answer

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

Question 48

Accepted Answer

Wetting is affected by electrolyte composition, viscosity, amount, electrode density, temperature, time, and vacuum conditions. Solutions include using low-viscosity solvents, adjusting salt concentration, increasing electrolyte volume, reducing electrode density, and applying vacuum or elevated temperature aging.

Question 49

Accepted Answer

Solid-state-specific carbon-group anodes are still under development; currently there are no such products. For solid-state-specific lithium metal anodes, lithium–indium alloy is available at present.

Question 50

Accepted Answer

We have a recommended compacted density value on our official website for the customer to refer to; if they want to achieve a compacted density within this range, the customer needs to verify it themselves to see the effect after pressing. Calendering according to a compacted density provided by the customer requires customization.

Question 57

Accepted Answer

Silicon monoxide is the anode material for lithium batteries; its surface has already been coated with carbon material; it is not pure silicon monoxide.

Question 58

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 59

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.

Supplier values are often device-level capacitance, while lab results may be material-level values. Conversion factors apply. Commercial materials prioritize stability and reproducibility.

Question 63

Accepted Answer

We don't have data on this anode material, but based on graphite, the electrode sheet color varies at different states of charge. You can ask the customer to perform an experiment: charge to different states, then disassemble the cell and observe
