Abstract

fetched live from OpenAlex

Ceramic Na superionic conductor (NASICON)‐type Na 3 Zr 2 Si 2 PO 12 solid‐state electrolyte is one of the prime candidates for Na metal solid‐state batteries due to its high room‐temperature ionic conductivity and electrochemical stability. However, a major challenge lies in integration of NASICONs with a Na anode due to the solid‐solid nature of the interface. Herein, the ductility of Na metal is capitalized and the impact of stack pressure and temperature in improving the interfacial properties of Na|NASICON symmetric cells is investigated. At 100 MPa stack pressure and 50 °C, the voltage polarization of the cells is approximately 10 times lower than those tested at 25 °C. The improved Na + ‐ion kinetics result in a higher critical current density and a stable Na cycling response over long durations. Postmortem studies confirm the presence of Na dendrites in the pores and along the grain boundary of the NASICON ceramic structure. The results demonstrate the dependence of interface kinetics on pressure and temperature in a Na 3 Zr 2 Si 2 PO 12 ‐based all‐solid state Na metal battery and presents a strategy for enabling stable operation of high‐energy, solid‐state Na batteries.

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.
