Molecular Dynamics Simulations of Polymer–Ionic Liquid (1-Ethyl-3-methylimidazolium Tetracyanoborate) Ternary Electrolyte for Sodium and Potassium Ion Batteries
Bibliographic record
Abstract
We have performed molecular dynamics (MD) simulations of 1-ethyl-3-methylimidazolium tetracyanoborate ([EMIM]+[B(CN)4]−) ionic liquid to investigate the impact of addition of Na+/K+[B(CN)4]− salts and poly(ethylene oxide) (PEO6) on transport properties. These ternary mixtures are promising electrolyte materials for Na+-ion and K+-ion batteries as alternatives to the traditional Li+-ion ones. In addition, local structure was assessed through radial distribution functions. Our main findings are the following: (1) when compared to systems with larger amounts of Na+ and K+, it was observed that lower concentrations enhance the overall ionic conductivity and decrease viscosity; (2) Na+ and K+ cations prefer to be coordinated to the polymer chains rather than the [B(CN)4]− anions; (3) transport properties are improved when PEO6 oligomers are included in the electrolyte medium but these improvements continue only up to an optimum amount of PEO6. Beyond this amount, further addition of PEO6 did not have any additional impact on transport properties.

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.
