Abstract

fetched live from OpenAlex

“We need more power Scotty!”. In STAR TREK as in lithium-ion batteries for transportation, power , is a major issue. The battery size in electric vehicles is generally increasing while it is clear that for most consumers, most of the time, the extra capacity will sit idle. This extra capacity, entails higher cost, higher energy consumption and higher environmental impact. Yet, consumers request longer driving autonomy, most likely since charging is still a comparably slow process. Thus, we need faster charging which translate into improved power performance. A strong tool to analyse and optimize power performance is numerical modeling. However, modeling requires a series of input geometric and materials parameters, some of which until now have been very difficult to obtain reliably. In this talk we will cover our recent advances to measuring these parameters and how these may help improve optimization of power performance. Specifically, in situ techniques based on scanning probes and synchrotron X-rays, as well as new battery chemistries will be discussed.

Full frame distilled prediction

Teacher imitation

Not 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.
