The Development of Pseudocapacitive Molybdenum Oxynitride Electrodes for Supercapacitors
Bibliographic record
Abstract
Mo oxynitride was developed as pseudocapacitive electrode material for supercapacitors. A thin film Mo oxynitride was produced by first electrodeposition of Mo oxide on a Ti substrate followed by a low-temperature (400 oC) heat treatment in N2 environment. XPS analyses showed that the surface of the Mo oxynitride film was composed of a mixture of MoO3, MoO2 and less than 20 at.% Mo2N. However, the electrochemical behavior of the Mo oxynitride film was significantly different from that of Mo oxide but much similar to the behavior of pure Mo2N, a known pseudocapacitive material. The cycle life and stability of the Mo oxynitride were much improved over the Mo oxide. A two-electrode symmetric cell using the developed Mo oxynitride electrodes was demonstrated and showed high rate performance. An asymmetric cell using a Mo oxynitride as negative electrode and a carbon as positive electrode was also established and showed an extended voltage window and, thus, an increased energy density.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
