Enhancement of Electrochemical Capacitance by Doping Rod-Like Mn Oxide Electrodes with Co
Bibliographic record
Abstract
The electrochemical properties of nanocrystalline Mn oxide and Mn-Co doped oxide electrodes, with and without a conducting polymer (PEDOT) coating, were investigated to determine the effect of morphology, chemistry and crystal structure on the corresponding electrochemical behavior of synthesized electrodes. Mn-Co oxide electrodes with rod-like structures were synthesized electrochemically by anodic deposition from an electrolyte solution of Mn acetate and Co sulfate on Au coated Si substrates. The electrochemical behavior of the deposits was studied by cyclic voltammetry at different scan rates. Also, microstructural characterization of as-deposited and cycled electrodes was conducted using SEM. The Mn-Co oxide/PEDOT electrodes showed improved specific capacity and electrochemical cyclability relative to uncoated Mn oxide, Mn-Co oxide and Mn oxide/PEDOT electrodes. A specific capacitance of ~310 Fg−1, with a capacitance retention of 92% of the original value, was obtained for Mn-Co/PEDOT electrodes after 250 cycles in 0.5M Na2SO4 at 100 mVs−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.
