Accurate estimation of the state charge (SOC) is essential for optimal operation batteries. However, to achieve such accuracy remains challenging tri‐electrode rechargeable zinc–air flow batteries (TRZAFBs) due their flat voltage profiles. This study presents an innovative SOC identification technique based on optimization battery model parameters derived from pulse response data. Model are extracted steps within experimental data, establishing correlations between these and SOC. Such then utilized as constraints in process. Results indicate that slope total resistance effectively identifies with acceptable accuracy. The proposed method further enhanced by integrating it extended Kalman filter (EKF) enable real‐time estimation. Various initial guess conditions frequencies tested, demonstrating EKF combined accurately tracks true corrects incorrect guesses. Additionally, results show can compete other alternative methods terms multiple‐cycle stability surpass them convergence (ZABs).

Abstract Rechargeable Zn–air batteries (ZABs) hold promise as the next‐generation energy‐storage devices owing to their affordability, environmental friendliness, and safety. However, cathodic catalysts are easily inactivated in prolonged redox potential environments, resulting inadequate energy efficiency poor cycle stability. To address these challenges, anodic active sites require multiple‐atom combinations, that is, ensembles of metals. Heterogeneous bimetallic atomically dispersed (HBADCs), consisting heterogeneous isolated single atoms atomic pairs, expected synergistically boost cyclic oxygen reduction evolution reactions ZABs tuneable microenvironments. This minireview revisits recent achievements HBADCs for ZABs. Coordination environment engineering catalytic substrate structure optimization strategies summarized predict innovation direction ZAB performance enhancement. These divided into ferrous nonferrous dual with unique microenvironments, including synergistic effects, ion modulation, electronic coupling, activity. Finally, conclusions perspectives relating future challenges opportunities provided optimise
