A lithium ion battery exploiting a composite Fe2O3 anode and a high voltage Li1.35Ni0.48Fe0.1Mn1.72O4 cathode
Bibliographic record
Abstract
In this paper we report a new lithium ion battery (LIB) consisting of a conversion-type, high capacity Fe2O3–Meso Carbon Micro Beads (MCMB) composite anode and a high voltage, Li1.35Ni0.48Fe0.1Mn1.72O4 cathode, prepared by using facile, low cost synthetic pathways. These electrodes have been characterized by a series of techniques including scanning and transmission electron microscopy, X-ray diffraction analysis, potentiodynamic cycling with galvanostatic acceleration (PCGA) and galvanostatic cycling tests in lithium cells at different C-rates. The results show that the Fe2O3–MCMB anode benefits by a composite, sub micrometric morphology and by a stable specific capacity ranging from 800 to 600 mA h g−1, evolving around 0.9 V, while the Li1.35Ni0.48Fe0.1Mn1.72O4 cathode is formed by an agglomeration of micrometric crystals delivering a reversible capacity of about 115 mA h g−1 at a 4.7 V high voltage. The combination of the Fe2O3–MCMB anode with the Li1.35Ni0.48Fe0.1Mn1.72O4 cathode leads to a complete lithium ion battery having an operating voltage of about 3 V, a high coulombic efficiency and a stable capacity of about 100 mA h g−1, which translates into in a theoretical energy density of about 300 Wh kg−1.

How this classification was reachedexpand
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.
