Characteristic of novel composition Nax[Ni0.6Co0.2Mn0.2]O2 as Cathode Materials for So-dium Ion-Batteries
Bibliographic record
Abstract
In this work, novel composition of Nax[Ni0.6Co0.2Mn0.2]O2 (x = 0.5 and 1.0) layered cathode materials were synthesized by using hydroxide co-precipitation and calcined at 850, 900 and 950 °C. We studied the effects of different sodium contents and calcination temperature on the structural and electrochemical properties of this novel cathode material. The change of calcination temperature and sodium content led to different P2-type, P2/P3-type, P2/O3-type, or O3-type structures. The results indicate better electrochemical perfor-mance of the P2-type cathode materials in terms of high discharge capacity and good cycling performance, when compared to P2/P3, P2/O3, and O3-type cathode materials. Na0.5[Ni0.6Co0.2Mn0.2]O2 electrode calcined at 900 °C exhibited a good capacity of 107.15 mAhg-1 and ca-pacity retention over 73 % after 20 cycle. Characterization of this material will help to develop cathode materials for the Na-ion battery cathode.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
