💡 Novelty & Significance:
The novelty lies in identifying cooling-driven oxygen-mediated reconstruction as a key synthetic lever controlling manganese vacancies and stacking faults in sodium manganese oxide cathodes. This challenges prior focus on pre-formed motifs. Its significance: kinetically regulating cooling enables a stacking-fault-rich architecture that suppresses Mn migration and irreversible oxygen release, establishing a general design principle for stabilizing oxygen-redox cathodes.
