pH-Controlled Synthesis of Electrolytic Manganese Dioxide Materials for Alkaline MnO<sub>2</sub>/Zn Batteries
Bibliographic record
Abstract
A systematic study of the effect of electrolysis acid concentration on the physical and electrochemical properties of electrolytic manganese dioxide (EMD) was conducted. High acid concentrations (> 2 M H2SO4), lead to multiphase production of manganese dioxide with poor electrochemical behavior; however, in low to mid-range acidic environments, superior EMD (compared to a commercial product) was obtained. With an electrolysis bath containing 1 M MnSO4 and 2 M H2SO4, the EMD produced had approximately twice the surface area (86.4 m2 gEMD-1) and structural water content (4.4 %) of that of a commercial sample. The aforementioned synthesized EMD furthermore had an improved energy efficiency and an average specific capacity of approximately 65 mAh gEMD-1 after 100 cycles showing about 25 mAh gEMD-1 higher capacity compared to the commercial sample.

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.
