Abstract

Abstract The development of high‐capacity, Earth‐abundant, and stable cathode materials for robust aqueous Zn‐ion batteries is an ongoing challenge. Herein, ultrathin nickel cobaltite (NiCo 2 O 4 ) nanosheets with enriched oxygen vacancies and surface phosphate ions (P–NiCo 2 O 4‐ x ) are reported a...
