Improving electrical conductivity and increasing the active site are important directions for improving technology of manganese-based cathode materials zinc ion batteries (ZIBs). In this paper, cobalt-doped oxygen-vacancy coupled MnO2 nanorods (Vo-CMO) were prepared by defect engineering an doping strategy as rechargeable ZIBs. Oxygen vacancies can increase density material provide more migration paths ions, thereby electrochemical activity specific capacity. The introduction cobalt adjust electronic structure manganese oxide, change Fermi level material, promote generation transmission charge carriers, transfer rate material. synergistic effect among them improve diffusion kinetics capacity cycle stability Vo-CMO has better Zn2+ storage 295.6 mAh·g–1 at 0.1 A·g–1. reaction mechanism was H+/Zn2+ coinsertion through galvanostatic current intermittent titration (GITT) ex situ experiments. addition, assembled flexible quasi-solid ZIB. oxygen vacancy a new way to develop water-based

ABSTRACT In the pursuit of advanced energy storage technologies that promote sustainable solutions, zinc‐ion batteries (ZIBs) have emerged as a promising alternative to lithium‐ion due their abundance, safety, and environmental advantages. However, failure mechanisms ZIBs under extreme temperatures are still not fully understood, presenting significant challenges development commercialization. Therefore, innovative strategies essential enhance adaptability temperature extremes. this review, we first explore thermodynamic kinetic aspects performance degradation temperatures, focusing on key factors such ion diffusion redox processes at electrode interfaces. We then comprehensively summarize discuss existing approaches for various electrolyte types, including aqueous, nonaqueous, solid state. Finally, highlight future prospects operating conditions. The insights presented in review expected accelerate advancement facilitate practical implementation large‐scale systems.

Abstract The wide band gap of δ‐MnO 2 and the restricted regulation p‐band center ( p ) active oxygen atoms hinder electron conduction ion diffusion during zinc storage. Heteroatom doping has proven effective in improving However, solely through cation is comparatively constrained. Herein, a cation/anion co‐doping strategy proposed to simultaneously adjust d‐band d Mn by establishing Mn–O–Ca Mn─N bonds Ca/N co‐doped (Ca/N‐MnO ). This effect induces shift predominant stretching vibration mode Mn─O [MnO 6 ] octahedra, resulting decreased d/p‐band proximity (Δ d‐p 1.688 eV (1.750 for Consequently, both adsorption capacity adsorption/desorption rates Zn 2+ /H + ions are enhanced. Theoretical calculations further reveal that significantly triggers optimization gap, migration energy barrier, energy. As result, Ca/N‐MnO achieves remarkable reversible 192.7 mAh g −1 at 1.0 A after 200 cycles exceptional rate performance. Furthermore, enhancement mechanisms thoroughly elucidated. synergistic offers significant potential efficient storage applications.
