High-specific surface area, three-dimensional reticulated electrodes for deep cycle lead-acid batteries
Bibliographic record
Abstract
Power Technology Inc. has developed two types of proprietary reticulated, high specific surface area (> 1000 m/sup 2/ m/sup -3/) current collectors for lead-acid batteries manufactured by casting and plating, respectively. The comparative performance of the reticulated and standard grid-type current collectors was studied by single-cell battery testing and scanning electron microscopy (SEM). The electrochemical utilization efficiency of the positive active mass (PAM) in flooded cells equipped with 25 - 30 pores per inch (ppi) reticulated collectors was up to 55% higher than for a grid battery at 3 h discharge rate. These results were attributed to differences in PAM morphology induced by the current collector design, as shown by SEM micrographs. The reticulated battery with Pb-Sn alloy current collectors subjected to daily cycling composed of continuous 19 h float charge at 2.35 V/cell followed by a 5 hour discharge, exhibited a capacity loss of less than 10% in 30 days.

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.
