P6C5 monolayer as promising anode for high-performance sodium-ion batteries: Insights from DFT and AIMD study
Bibliographic record
Abstract
Recently, a lateral heterostructure (LHS) combining black phosphorene and graphene edges was developed, addressing volume change issues and enhancing capacity retention. However, unresolved geometric concerns require further investigation, particularly regarding its suitability as a sodium-ion battery (SIB) anode. We present three LHSs models, labeled (LHS PC)1, (LHS PC)2, and P5C6, all featuring edge contact symmetry (armchair direction) but with different interface defects. Through first-principles calculations, we compare their structural stability, electronic properties, and charge transfer mechanisms. P5C6 exhibits superior energetic stability and dynamic stability, with type II band alignment and a 0.73 eV direct band gap, indicating optimal charge diffusion. Electrochemical assessments reveal a low sodium migration barrier (0.019 eV), facilitating rapid charge-discharge rates, with a storage capacity of 590.5 mAh/g and intercalation at a low average voltage (0.27 V). Additionally, ab initio molecular dynamics (AIMD) confirm its thermal stability during sodium storage, underscoring P5C6's potential as a promising SIB anode material.

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.
