Influence of Calcination Temperature on the Electrochemical Performance of Li1.2[Ni0.13Co0.13Mn0.54]0.985Zr0.015O2 as Li-rich Cathode Material for Li-ion Batteries
Bibliographic record
Abstract
In this work, Li1.2[Ni0.13Co0.13Mn0.54]0.985Zr0.015O2 cathode material was synthesized via combustion synthesis method.The product was annealed at different temperatures of 650, 750 and 850 ° C for 12 h.The effect of annealing temperature on electrochemical performance of synthesized powder was investigated using charge/discharge performance, cyclic voltammetry and impedance tests.X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM) were used for phase identification and investigating the morphology of the samples.According to charge/discharge diagrams, the sample calcined at 750 ° C exhibited the highest initial discharge capacity of 254 mAh/g at current density of 25 mA/g.The highest cyclic stability was obtained at 750 ° C so that the remained capacity after 50 cycles was about 97%.Impedance tests and Nyquist diagrams revealed that the lowest impedance is observed at 750 ° C.

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.
