Walnut-like MoO <sub>2</sub> with interconnected skeleton and opened muti-channel for fast sodium storage
Bibliographic record
Abstract
Abstract Molybdenum dioxide (MoO 2 ) has attracted lots of theoretical interest as an anode material for sodium ion batteries (SIBs) due to its high theoretical capacity (836 mA h g −1 ) and metallic electrical conductivity (1.9 × 10 2 S cm −1 ). The insertion reaction, forming Na 0.98 MoO 2 and the reversible conversion reaction, forming Mo and Na 2 O from Na 0.98 MoO 2 contribute capacities of 209 and 627 mA h g −1 , respectively, the latter occupies 75% of the totally theoretical capacity. However, intrinsic slow kinetics in bulk MoO 2 severely restricts the redox conversion reaction. In the present work, a walnut-like MoO 2 architecture (W-MoO 2 ) with opened multi-channel and interconnected skeleton was prepared in a tube furnace, providing an interconnected ion/electron dual-pathway, which effectively facilitates Na + diffusion and reduces the internal resistance of the cells. The W-MoO 2 anode demonstrates an enhanced reversible sodium storage capacity of 354.7 mA h g −1 at 0.5 A g −1 .

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.
