Salt-Solvent-Polymer Interactions Influence Lithium Salt Distribution in Thermoplastic Vulcanizate Electrolytes
Bibliographic record
Abstract
Lithium ion mobility in solvent-doped solid polymer electrolytes depends on interactions between the salt, the polymer and absorbed solvents. This work presents novel electrolytes based on thermoplastic vulcanizates which have been shown to possess the mechanical and electrochemical stability of the elastomeric phase along with the mobility and processability of the thermoplastic phase. Although modest ionic conductivities were obtained for the as-prepared electrolytes, the addition of lithium salt-containing solvents improved conductivity by about 2 orders of magnitude. The presence of multiple lithium salt dissociating phases raises questions regarding the distribution of lithium salt in the electrolyte and the participation of each phase in ion conduction. Ionic conductivity, NMR spectroscopy measurements of salt distribution and ion mobility and vibrational spectroscopy of lithium-coordinating functional groups showed that lithium salts exist in a solvent-swelled polymer phase wherein ionic conductivity depends on a combination of lithium salt distribution, solvent-polymer interactions and local-scale polymer mobility.

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.
