Uncovering the role of atmosphere on thermal stability of NASICON type solid electrolytes and oxide-based cathode materials via high temperature X-ray diffraction
Bibliographic record
Abstract
Thermal stability of NASICON type solid electrolytes, Li 1.4 Al 0.4 Ti 1.6 (PO 4 ) 3 (LATP) and Li 1.25 Al 0.25 Ge 1.75 (PO 4 ) 3 (LAGP), were studied against LiCoO 2 (LCO), Al-doped LiNi 0.6 Mn 0.2 Co 0.2 O 2 (NCM), LiMn 2 O 4 (LMO) and LiCoPO 4 (LCP) in both air and inert gas. An in-situ high temperature X-ray diffractometer was employed to monitor phase changes during the co-sintering of the electrolytes-cathode composites. The effect of atmosphere on the thermal stability of LATP/LAGP is closely related to the stability of cathode material in the composite. LATP and LAGP are less stable in air than in inert gas when in contact with NCM and LCO. However, their thermal stabilities are similar in both air and inert gas when mixed with LMO and LCP. In the composite samples of LATP/LAGP+LMO, only traces of the impurities were detected at 700 °C due to the decomposition of LATP/LAGP. The initial lithium rich LMO loses approximately 5 % of its lithium but retains the same crystal structure. Therefore, the LATP/LAGP + LMO could be promising composite cathodes.

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.
