Manipulating the Crystalline Structure and Electrochemical Performance of a Dilithium Manganese Silicate Cathode Material by Polyanion Doping
Bibliographic record
Abstract
Abstract As a promising candidate for lithium‐ion battery cathodes, dilithium manganese silicate (Li 2 MnSiO 4 ) has high theoretical capacity (333 mA h g −1 ) and compatible working potentials resulting in high energy density. However, the material suffers from low electronic conductivity and severe capacity loss as a result of structural instability during charge and discharge. Herein, a strategy to manipulate crystalline structure through incorporating boracic polyanions into the lattice of Li 2 MnSiO 4 is presented to achieve preferential growth of an orthorhombic Pmn 2 1 structure, which has proven difficult to achieve through traditional synthesis methods. The modified cathode material exhibits improved cycling stability and excellent rate capability. The excellent electrochemical performance is due to the higher structural consistency, the pillar effect of the boracic polyanions and enlarged Li + pathways in the structure.

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.
