Abstract
All-solid-state batteries (ASSBs) have gained considerable attention due to their inherent safety and high energy density. However, fabricating ultrathin and freestanding solid electrolyte membranes for practical all-solid-state pouch cells remains challenging. In this work, polytetrafluoroethylene (PTFE) fibrilization was utilized to interweave inorganic solid electrolytes (SEs) into freestanding membranes. Representative SE membranes, including Li6PS5Cl, Li3InCl6, and Li6.5La3Zr1.5Ta0.5O12, demonstrate not only a thickness of 15–20 μm but also high room-temperature ionic conductivity (>1 mS cm–1). All-solid-state pouch cells with bilayer Li6PS5Cl and Li3InCl6 membranes deliver a high capacity of 124.3 mAh g–1 at 0.1 C and an initial Coulombic efficiency of 89.4%. Furthermore, using a 20 μm LLZTO membrane as a ceramic separator, a solid-state pouch cell with a high-capacity LiNi0.8Mn0.1Co0.1O2 electrode (>3 mAh cm–2) displays both exceptional cycling stability and unprecedented safety. We believe that this solvent-free technology would be a feasible and cost-effective means of transferring ASSB technology from the laboratory to the factory.

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 it
