Imitating Architectural Mortise‐Tenon Structure for Stable Ni‐Rich Layered Cathodes
Bibliographic record
Abstract
Abstract Ni‐rich layered oxides are the most promising cathodes for Li‐ion batteries, but chemo‐mechanical failures during cycling and large first‐cycle capacity loss hinder their applications in high‐energy batteries. Herein, by introducing spinel‐like mortise‐tenon structures into the layered phase of LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811), the adverse volume variations in cathode materials can be significantly suppressed. Meanwhile, these mortise‐tenon structures play the role of the expressway for fast lithium‐ion transport, which is substantiated by experiments and calculations. Moreover, the particles with mortise‐tenon structures usually terminate with the most stable (003) facet. The new cathode exhibits a discharge capacity of 215 mAh g −1 at 0.1 C with an initial Coulombic efficiency of 97.5%, and capacity retention of 82.2% after 1200 cycles at 1 C. This work offers a viable lattice engineering to address the stability and low initial Coulombic efficiency of the Ni‐rich layered oxides, and facilitates the implementation of Li‐ion batteries with high‐energy density and long durability.

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.
