Abstract
The intercalation of water into P2-Na 2/3 [Co x Ni 1/3 - x Mn 2/3 ]O 2 ( x = 0, 1 / 6, 1 / 3 ) and T2 or O2 structure Li 2/3 [Co x Ni 1/3 - x Mn 2/3 ]O 2 ( x = 0, 1 / 6, 1 / 3 ) has been investigated by X-ray diffraction and thermogravimetric analysis (TGA). Water can be intercalated into P2-Na 2/3 [Co x Ni 1/3 - x Mn 2/3 ]O 2 ( x = 1 / 6, 1 / 3 ) but not within P2-Na 2/3 [Ni 1/3 Mn 2/3 ]O 2 . This difference may be related to the existence of superlattice ordering of Ni atoms, but not Co atoms, within the transition metal layer which apparently induces a very strong interlayer interaction and inhibits the uptake of water. Two water-containing phases of P2-Na 2/3 (H 2 O) y [Co 1/3 Mn 2/3 ]O 2 were found and one, with y ≈ 2/3, could be prepared in pure form. By Rietveld refinement of the X-ray diffraction pattern of P2-Na 2/3 (H 2 O) 2/3 [Co 1/3 Mn 2/3 ]O 2, it can be concluded that the compound still exists in the ideal P2 structure ( P 6 3 / mmc ) with the oxygen atoms of the water molecule located on the 2c site. Water cannot be intercalated into the corresponding lithiated phases, Li 2/3 [Co x Ni 1/3 - x Mn 2/3 ]O 2 for any value of x that we tested ( x = 0, 1 / 6, 1 / 3 ).

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; both teacher heads agree on what is shown here.
