Quantifying Electrolyte Motion in Cylindrical Li-Ion Cells using Rotational Inertia Measurements
Bibliographic record
Abstract
State-of-the-art cylindrical Li-ion cells can be susceptible to degradation in the form of accelerated inhomogeneous lithium plating on the negative electrode, which has recently been shown to be caused by an electrolyte motion-induced salt inhomogeneity in the electrolyte. Electrolyte motion is caused by the cyclic expansion and contraction of the electrode active materials at different states of charge, which displaces some of the electrolyte back and forth between the pores of the electrodes and the empty and inactive areas located at the ends of the cylindrical cell and in the core of the electrode winding. To study electrolyte motion, rotational inertia measuring (RIM) instruments have been developed, which are torsional oscillators that detect changes in the resonant frequency of a cylindrical cell as its mass distribution changes during cycling. Resonant frequency changes are used to calculate the amount of displaced electrolyte in relation to the state of charge of the cell. RIM instruments are effective for studying electrolyte motion in a variety of cylindrical cell formats, with the goal of understanding and reducing the impact of electrolyte motion on cell degradation.

How this classification was reachedexpand
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.
