Dependence of the Electrochemical and Passive Behavior of the Lead-Acid Battery Positive Grid on Electrode Surface Roughness
Bibliographic record
Abstract
The corrosion resistance of the positive grid alloy plays an important role on the performance and service life of lead-acid batteries. There are many parameters influencing the corrosion behavior of the grid alloy. Grid surface roughness, which is of importance from a manufacturing point of view, is a parameter that has received rather less attention. In the present study, the dependence of the electrochemical and the passive behavior of the positive grid alloy on electrode surface roughness was investigated. Cyclic voltammetry, potentiodynamic polarization, galvanostatic polarization, electrochemical impedance spectroscopy, and Mott-Schottky analysis were used to evaluate the influence of surface roughness on the electrochemical properties of the grid alloy. The results indicated that increasing the surface roughness hindered formation of the passive film and increased the corrosion resistance of the lead alloy electrode. Moreover, it was found that the donor density of the passive film is proportional to the surface roughness.

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.
