Abstract
Abstract High Li + conductivity, good interfacial compatibility and high mechanical strength are desirable for practical utilization of all‐solid‐state electrolytes. In this study, by introducing Li 6.4 La 3 Zr 1.4 Ta 0.6 O 12 (LLZTO) with surface defects into poly(ethylene oxide) (PEO), a composite solid electrolyte (OV‐LLZTO/PEO) is prepared. The surface defects serve as anchoring points for oxygen atoms of PEO chains, forming a firmly bonded polymer‐ceramic interface. This bonding effect effectively prevents the agglomeration of LLZTO particles and crystallization of PEO domains, forming a homogeneous electrolyte membrane exhibiting high mechanical strength, reduced interfacial resistance with electrodes as well as improved Li + conductivity. Owing to these favorable properties, OV‐LLZTO/PEO can be operated under a high current density (0.7 mA cm −2 ) in a Li–Li symmetric cell without short circuit. Above all, solid‐state full‐cells employing OV‐LLZTO/PEO deliver state‐of‐the‐art rate capability (8 C), power density and capacity retention. As a final proof of concept study, flexible pouch cells are assembled and tested, exhibiting high cycle stability under 5 C and excellent safety feature under abusive working conditions. Through manipulating the interfacial interactions between polymer and inorganic electrolytes, this study points out a new direction to optimizing the performance of all‐solid‐state batteries.

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 it
