Abstract

fetched live from OpenAlex

It is highly desirable to realize high-energy-density lithium-ion batteries consisting of nickel-rich layered oxide cathodes (Ni-rich NMC) and Si-based anodes. A critical challenge for Ni-rich NMC is its fast capacity degradation. In addition, the low initial Coulombic efficiency of the Si-based anode consumes the electrochemically active lithium from the cathode and decreases the energy density of full batteries considerably. We consider cathode and anode as a whole to simultaneously resolve the issues of both sides. Ni-rich LiNi0.65Mn0.20Co0.15O2 (LR-Ni65) consisting of a lithium-enriched gradient interphase layer (∼20 nm) is designed to supply excess electrochemically active lithium to compensate lithium loss at the anode and enhance cycling stability through regulating Li/Ni disorder in the cathode structure. We show that a LR-Ni65||Si/graphite pouch cell displays a capacity (3.29 Ah) greater than that for the counterpart using pristine Ni-rich NMC (2.95 Ah), as well as enhanced cycling stability with 88% capacity retention. The good compatibility with current Ni-rich NMC processing and facile synthesis make the as-fabricated cathode material promising for practical commercial application.

Full frame distilled prediction

Teacher imitation

Not 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.
