Sulfur Refines MoO<sub>2</sub> Distribution Enabling Improved Lithium Ion Battery Performance
Bibliographic record
Abstract
We employ a sulfur-assisted decomposition process to create agglomerates of large (200–500 nm) yet highly nanoporous three-dimensional MoO 2 single crystals partially covered with a few atomic layers of MoS 2 (“MoS 2 /MoO 2 nanonetworks”). These materials are highly promising as lithium ion battery anodes. At a current density of 100 mA g –1, the MoS 2 /MoO 2 nanonetworks exhibit a reversible discharge specific capacity of 1233 mAh g –1, with only 5% degradation after 80 full charge/discharge cycles. Moreover at the relatively fast discharging rates of 200 and 500 mA g –1, the capacities are 1158 and 826 mAh g –1, respectively. A comparison with literature shows that these are among the more promising reversible capacity, cycling capacity, and rate capability values reported for MoO 2 . The electrochemical properties are attributed to the material’s nanoporous crystal morphology that allows for facile reversible transport of Li ions without either disintegration or agglomeration of the structure.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
