Question 1

Accepted Answer

What is the purpose of the experiment? For preparing composite electrolyte membranes, choose the solvent based on the lithium salt used; you can consider DMAC   acetone. Of course, for specific solvent selection and usage, consult relevant literature for your experiment.

Question 2

Accepted Answer

Graphite

Question 3

Accepted Answer

It has not been lithiated; it is just a regular graphite anode electrode.

Question 4

Accepted Answer

Aluminum foil

Question 5

Accepted Answer

Our graphite electrode test results are on the official website

Question 6

Accepted Answer

SBR CMC

Question 7

Accepted Answer

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

Question 8

Accepted Answer

The LATP side faces the positive electrode. LATP is easily reduced by lithium metal.

Question 9

Accepted Answer

Conductive carbon: SP, CNT; binder: PVDF-5130

Question 10

Accepted Answer

The electrode foil is a double-sided carbon-coated aluminum foil; the other side is coated with a carbon layer

Question 11

Accepted Answer

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

Question 12

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 13

Accepted Answer

KS-6 itself is a conductive agent and is generally not used as a negative electrode active material. If it were to be used as a negative electrode active material, it should not be necessary to add Super P.

Question 14

Accepted Answer

Yes

Question 15

Accepted Answer

There is related data in the electrode sheet parameters on the official website

Question 16

Accepted Answer

LiFePO₄ has low conductivity. Carbon-coated aluminum foil reduces internal resistance, improves adhesion, and helps prevent electrode cracking.

Question 17

Accepted Answer

The ternary electrolyte from the official website

Question 18

Accepted Answer

The electrode interface of the electrochemical workstation from Shanghai Chenhua is like this, and it’s different from this connector,

Question 19

Accepted Answer

Punched sheet weight * active material ratio (96%) = weight of the active material

Question 20

Accepted Answer

Use metallic lithium as the reference electrode

Question 21

Question 22

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 23

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 24

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 25

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 26

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 27

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 28

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.

Question 29

Accepted Answer

Compared with polycrystalline cathode materials, single-crystal cathodes have somewhat poorer conductivity; you need to increase the conductive additive content based on their standard formulation. Alternatively, if you do not want to raise the total conductive additive content, you can replace part of the conductive carbon with CNTs.

Question 30

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

Question 31

Accepted Answer

RRDE, short for the Rotating Ring-Disk Electrode (Rotating Ring-Disk Electrode), is a special electrode device for electrochemical research, capable of simultaneously measuring the main reaction (occurring on the disk electrode) and detecting the intermediate product (captured by the ring electrode). Although the term is not directly mentioned in the provided document, it belongs to advanced electrochemical characterization techniques and is often used in reaction mechanism studies. This conclusion is based on common knowledge in the field of expertise.
