Abstract In advancing aqueous zinc‐ion batteries (AZIBs) toward commercial viability, vanadium (V)‐based cathodes are pivotal, offering broad redox ranges, and compatibility with water's electrochemical limits. Despite their great potentials, V‐based face challenges in transitioning from lab to commercialization. Defect engineering is exploited as a pivotal technique that endows the unexpected physical chemical properties break intrinsic bottleneck and, turn, enhance performances. This review delves into role of defect on materials, underscoring its potential mitigating critical challenges. It starts by encapsulating current characteristics AZIBs. Research efforts related various defects, such oxygen vacancies, cation cationic doping, anionic water intercalation, lattice disorders/amorphization, then rationalized discussed. The fabrication characterization techniques also summarized. By integrating conclusions existing works tailoring strategies, few perspectives provided for systematically employing pave way more efficient transition these promising materials laboratory breakthroughs commercially viable energy storage solutions.

Unlocking the Crucial Role of Oxygen Vacancies on the Low‐Temperature Li‐Ion Storage

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 7, 2025

Abstract Designing crystal structures that enable fast Li‐ion transport is essential for achieving high performance in oxide electrodes low‐temperature lithium‐ion batteries (LT‐LIBs), especially micron‐scale particles. The introduction of point defects considered to be effective accelerating local at room temperature, but due the discontinuity defects, enhancement low temperatures remains verified. Besides, understanding defect impact quite limited. In this study, a vanadium pentoxide (V 2 O 5 ) cathode with abundant oxygen vacancies bulk phase successfully synthesized. Such structure tends form continuous and channels, facilitating deep lithiation ultralow exceptional rate capability impressive capacitance retention (74% −40 °C 54% −50 °C). Remarkably, an empirical relationship between storage oxides uncovered. Specifically, degree exhibits two distinct trends depending on temperature: linear increase response vacancy concentration above °C, exponential below threshold. insights gained here highlight crucial role concentrations temperatures, providing direction tackling critical challenges battery technologies.

Environmental concerns promote the development of sustainable energy storage devices. Resource-rich vanadium oxides with easily adjustable valence still exhibit unsatisfactory electrochemical performance stemming from poor electrical conductivity and friable structure as aqueous zinc-ion battery (AZIB) cathodes. Herein, oxide (VO-300) enriched oxygen vacancies is acquired via a convenient solvothermal method in combination subsequent heat treatment, which exhibits remarkable rate 411.98 mAh·g–1, an excellent cycling life for 1500 cycles 92.8% retention at 10 A·g–1. The enhanced performances VO-300 can be attributed to more vacancies, provide active sites storage, expand layer spacing, increase V2O5. More pivotal, activation phenomenon analyzed, two-carrier conversion insertion mechanism H+ domination Zn2+ proposed. Based on this mechanism, V2O5 transformed into ZnxV2O5·nH2O material leading faster kinetics. This work not only demonstrates potential application cathode but also provides new insights mechanism.
