Question 1

Accepted Answer

Our graphite electrode test results are on the official website

Question 2

Accepted Answer

Cold pressing at 300 MPa, holding a pressure of 30 MPa during testing.

Question 3

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 4

Accepted Answer

We haven't measured this data; the customer needs to test it themselves.

Question 5

Accepted Answer

Yes, it can be used; for the exact wiring, have the instructor contact the electrochemical workstation's technical support.

Question 6

Accepted Answer

This separator is the Celgard 2500 separator. We ourselves have not tested it the way the customer did. When we use it, we assemble cells directly and test cell performance.

Question 7

Accepted Answer

The ternary electrolyte from the official website

Question 8

Accepted Answer

In half-cells, all tested materials act as the cathode, while lithium metal is the anode. Charging corresponds to delithiation of the test material; discharging corresponds to lithiation.

Question 9

Accepted Answer

The test temperature depends on the battery test items required, but tests are generally conducted at room temperature.

Question 10

Accepted Answer

rest 2h, 0.2C DC to 0V, 0.1C DC to 0V, 0.01C DC to 0V, 10 μA DC to 0V, rest 3 min, 0.1C CC to 2V — this is the first cycle gravimetric capacity test step

Question 11

Accepted Answer

Every current needs to discharge down to 0.005 V

Question 12

Accepted Answer

rest 4h, 0.2C DC to 0V, 0.1C DC to 0V, 0.01C DC to 0V, 10μA DC to 0V, rest 3 min, 0.1C CC to 2V. This is the test procedure.

Question 13

Accepted Answer

We don't have more cycling data updates for now; we will test and complete them later.

Question 14

Accepted Answer

It is normal; it should be on the official website. This varies with different electrolytes; 90%–94% is all normal.

Question 15

Accepted Answer

The electrolyte pellets are simply ground and polished, then gold-sputtered on both faces, leaving the edges unsputtered. The gold-coated pellet is clamped between the two faces with a coin-cell test clip for measurement.

Question 16

Accepted Answer

Particle size analyzer measured; under conditions of a drying oven with a dew point below -50°C, short-term rapid testing is fine.

Question 17

Accepted Answer

Ionic conductivity is on the product detail page of the official website. Some nano-scale modifications have been done, making water and air resistance slightly better. Specific details are not convenient to disclose.

Question 18

Accepted Answer

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

Question 19

Accepted Answer

Such fluctuations are generally caused by insufficient battery stability. Did the customer previously assemble batteries of other systems, and were those test results stable?

Question 20

Accepted Answer

There are no specific gold-sputtering parameters because instruments vary, but there is an evaluation criterion: after gold plating, use a multimeter to test the resistance between any two points; values close to 1 ohm are ideal. The lower the vacuum during gold sputtering, the better. Continuous runs are not recommended because the plating equipment can become hot inside, and temperature will affect the evaporation/plating results.

Question 21

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.
