High‐Rate Rechargeable Li/SOCl <sub>2</sub> Batteries Enabled by Cobalt Phthalocyanine Cathodic Catalysts
Bibliographic record
Abstract
Abstract Rechargeable lithium/thionyl chloride (Li/SOCl 2 ) batteries are considered promising alternatives to lithium‐ion batteries because of their ultrahigh energy density and wide operating temperature range. However, current rechargeable Li/SOCl 2 batteries exhibit unsatisfactory rate performance that originates from the poor reversibility of SOCl 2 and is dominated by the difficulty in oxidizing the discharge product lithium chloride (LiCl). In response to this issue, cobalt phthalocyanine (CoPc) is employed as a cathode catalyst to boost the oxidation kinetics of LiCl products and thus improve the reversibility of SOCl 2 in rechargeable Li/SOCl 2 batteries. The CoPc catalyst in the Li/SOCl 2 batteries is found to not only promote the discharge reduction of SOCl 2 but also remarkably accelerate the reversible charge transformation of LiCl products by lowering the chloride ions oxidation barrier. The CoPc‐catalyzed Li/SOCl 2 batteries deliver a high specific capacity of 800 mAh g −1 at a current density of 500 mA g −1 , with a stable voltage plateau of 3.5 V over 200 cycles. Even at the ultrahigh current density of 5 mA cm −2 , these batteries can still provide a reversible capacity of 1 mAh cm −2 over 250 cycles, demonstrating excellent rate performance.

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.
