Investigations on Lithium Carbonate-alumina Composite Solid Electrolyte: Morphology and Related Conductivity
Bibliographic record
Abstract
Composite solid electrolytes in the system (1-x)Li2CO3-xAl2O3 with x = 0.1 – 0.6 mole were prepared via sol-gel technique. The morphology and conductivity of the composite were investigated. Obtained materials were analysed by X-ray diffraction, differential scanning calorimetry, scanning electron microscopy, Fourier transform infrared spectroscopy and chemical constituents were confirmed by energy dispersive X-ray. The ionic conductivity was measured using AC impedance spectroscopy. SEM studies of cross-section morphology clearly showed lithium carbonate crystals became radial – fluffy shaped particularly at x = 0.1 and 0.6. Morphological analysis showed homogeneous distribution between Li2CO3 and Al2O3 particles resulted in formation of amorphous phase of Li2CO3 at Li2CO3 - Al2O3 interface. Traces of α-LiAlO2, γ-LiAlO2 and LiAl5O8 were observed at x = 0.1, 0.2 and x = 0.4. Impedance spectroscopy studies showed that the conductivity is maximal at x = 0.2 and 0.4 - 0.5 with a value equal to ~10-3 Scm-1 with temperatures ranging from 130 - 180 oC.

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.
