Dendrite initiation and deflection in biaxially compressed solid electrolytes
Bibliographic record
Abstract
Lithium metal solid-state batteries offer advantages of high energy density and improved safety compared with lithium ion batteries. However, solid-state batteries fail through short-circuiting even at low charging rates (<1 mA/cm2) due to lithium dendrite initiation and propagation. The location of dendrite initiation is still under debate, particularly between initiation at the surface and within the interior of the solid electrolyte. Here, we develop an in-plane biaxial compression method that provides direct evidence of dendrite initiation within the interior of garnet solid electrolytes. The biaxial compression also deflects dendrite propagation to be perpendicular to the electric field direction and prevents short-circuiting at extreme fast charging of 100 mA/cm2. This approach demonstrates the use of mechanics to address pressing challenges in next generation batteries.

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.
