A High Capacity All Solid‐State Li‐Sulfur Battery Enabled by Conversion‐Intercalation Hybrid Cathode Architecture
Bibliographic record
Abstract
Abstract As demands for electrochemical energy storage continue to rise, alternative electrochemistries to conventional Li‐ion batteries become more appealing. Here, an intercalation‐conversion hybrid cathode that combines intercalation‐type VS2 with conversion‐type sulfur chemistry to construct high performance solid‐state lithium‐sulfur batteries is reported. The layered VS2 nanomaterial features Li‐ion transport channels, metallic conductivity, and active capacity contribution, all of which provide an ideal platform for the solid state S/Li2S redox couple to unlock its high gravimetric capacity. The S/VS2/Li3PS4 hybrid cathode composite is prepared by a facile, low‐cost, and low‐energy mechanical blending process. The S/VS2/Li3PS4|Li3PS4|Li/In (or Li) all‐solid‐state cell exhibits sulfur utilization of ≈85%, with a Coulombic efficiency of close to 100%. High areal capacity up to 7.8 mA h cm−2 with an active material loading (S/VS2) as high as 15.5 mg cm−2 is achieved.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
