Enhancing the Kinetics of Lithium/Sodium Transition Metal Orthosilicate Cathodes through Tuning the Crystallographic Habits
Bibliographic record
Abstract
Lithium transition metal orthosilicates, Li 2 MSiO 4 (M=Mn, Fe, Co), have received great attention because of the theoretical possibility to reversibly deintercalate two Li + ions from the silicate structure. However, the silicates still suffer from low electronic conductivity, sluggish lithium ion diffusion and poor structural integrity upon electrochemical cycling. Recently, sodium transition metal orthosilicates, Na 2 MSiO 4 (M=Mn, Fe, Co), have been reported to be used as a cathode material for sodium secondary battery. In this research, lithium/sodium transition metal orthosilicate A 2 MSiO 4 (A=Li or Na; M= Mn, Fe or Co) nanostructures with preferential exposures of various crystallographic planes on the surface were synthesized via a facile and efficient solvothermal process. Detailed microscopic and spectroscopic analyses are performed to get a better understanding of the electrochemical performance-structure correlations in the crystal habit-tuned A 2 MSiO 4 nanostructures. We anticipate that this novel strategy should shed light on the design and development of a wide range of high capacity intercalated cathode materials for lithium/sodium ion batteries.

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.
