Sample assessment
The material was identified only as a battery powder. Electrode chemistry, starting distribution and electrochemical requirements were not supplied.
Analyst consideration: A battery-material powder may have functional requirements beyond size, including surface or structural attributes. Since the chemistry is unknown, selection should start by identifying which of those attributes must survive milling.
Recorded objective
Observe the milling response; no numerical size target was recorded.
Equipment and selection
The machine entry is XQM. TENCAN Vertical square planetary ball mill is associated at the recorded series level. No exact housing variant is inferred from jar capacity or an abbreviated machine label.
Test setup
| Jar entry | Zirconia 250 |
|---|---|
| Media entry | Zirconia 250 |
| Media-charge notation | 1-100/2-50/3-50/1015*25 |
| Sample-load entry | 80 (unit not stated) |
| Controller speed setting | 500 |
| Cycle notation | 5/1 |
Unlabelled jar, media and load numbers remain source notation, not assigned units. Controller settings are not certified rpm. The cycle notation has no independently stated timing unit or reversing definition.
Recorded procedure and results
The setup records a zirconia jar, zirconia media and a controller setting of 500. At two hours the sample was described as very fine; the result column repeats that favorable description. The record provides no D50, D90, morphology image, contamination result or electrochemical test.
Interpretation
The source supports a favorable physical fineness observation for the particular sample. It cannot establish a battery-performance improvement or a nanometre-size claim, and the compact media notation is not a complete reproducible specification.
Practical precautions
Confirm the battery chemistry and define a distribution metric for the next trial. Keep electrochemical and contamination checks separate from the visual assessment of the milled powder.
TENCAN alternatives to evaluate
TENCAN Planetary ball mill (semi-circular model). For this battery powder, a compatible benchtop configuration can be compared using the same two-hour sample. Confirm chemistry and a measurable fineness criterion before judging either setup. A compatible benchtop jar is a capacity-and-handling comparison for the laboratory charge; it should be judged using the identified battery chemistry and a measured endpoint, not the favorable appearance alone. This is an untested comparison proposal, not a result of this trial.
Association follows the explicit XQM source entry; only recorded tested series/configurations are related. No jar-volume inference.
About this trial
TENCAN laboratory trial, 2017–2020. Observations above come from this experimental record; selection considerations and proposed comparisons are engineering interpretation. Results apply to this sample and recorded conditions.
