Abstract
In this study, we investigated the effect of postannealing on the properties of a garnet-type Ta-doped Li6.55La3Zr1.55Ta0.45O12 (Ta-LLZO) ceramic solid electrolyte degraded by lithium (Li) dendrite penetration during electrochemical Li plating and stripping testing in a Li/Ta-LLZO/Li symmetric cell. After the electrochemical testing in the symmetric cell, the Ta-LLZO pellet was taken out of the cell and then annealed at 800 or 900 °C for 4 h in air. It was confirmed that locally discolored spots on the Ta-LLZO surface at which Li dendrite penetrated disappeared after postannealing. The total conductivity of the annealed Ta-LLZO pellet was lower than the initial one but was retained above 10–4 S cm–1 at room temperature. When the soft-shorted or degraded area size by Li dendrite penetration is localized and smaller than the area size for Ta-LLZO, it is expected that the degradation of the conductivity of annealed Ta-LLZO becomes smaller. Obtained electrochemical results indicate the possibility of reusing the degraded garnet-type solid electrolyte by Li dendrite penetration in another all-solid-state Li battery.

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 it
