Novel Synthesis of Plate-like LiFePO4 by Hydrothermal Method
Bibliographic record
Abstract
Lithium iron phosphate (LiFePO4) was prepared by hydrothermal synthesis method using FeSO4·7H2O and LiH2PO4 as resource of Li and Fe. The ratio of Li: Fe was maintained 1:1. The results suggested that pH value played a crucial role in the synthesis of LiFePO4, especially for the generation of impurities. We found that adding citric acid to the precursor was an effective way for chelating ferrous ions, thereby preventing the undesirable iron compounds during hydrothermal treatment. The particle morphology and the crystal orientation of the prepared LiFePO4 particles were investigated by the XRD and SEM results. The X-ray diffraction pattern of the samples indicated that single-phase LiFePO4 were successfully synthesized by hydrothermal method with a stoichiometric 1:1 ratio of Li :Fe.

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.
