Abstract
Abstract Despite the increasing effort in advancing oxygen electrocatalysts for zinc‐air batteries (ZABs), the performance development gradually reaches a plateau via only ameliorating the electrocatalyst materials. Herein, a new class of external field‐responsive electrocatalyst comprising Ni 0.5 Mn 0.5 Fe 2 O 4 stably dispersed on N‐doped Ketjenblack (Ni 0.5 Mn 0.5 Fe 2 O 4 /N‐KB) is developed via polymer‐assisted strategy for practical ZABs. Briefly, the activity indicator Δ E is significantly decreased to 0.618 V upon photothermal assistance, far exceeding most reported electrocatalysts (generally >0.680 V). As a result, the photothermal electrocatalyst possesses comprehensive merits of excellent power density (319 mW cm −2 ), ultralong lifespan (5163 cycles at 25 mA cm −2 ), and outstanding rate performance (100 mA cm −2 ) for liquid ZABs, and superb temperature and deformation adaptability for flexible ZABs. Such improvement is attributed to the photothermal‐heating‐enabled synergy of promoted electrical conductivity, reactant‐molecule motion, active area, and surface reconstruction, as revealed by operando Raman and simulation. The findings open vast possibilities toward more‐energy‐efficient energy applications.

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
