Vanadium Hexacyanoferrate Prussian Blue Analogs for Aqueous Proton Storage: Excellent Electrochemical Properties and Mechanism Insights

Small, Journal Year: 2023, Volume and Issue: 20(2)

Published: Sept. 5, 2023

Abstract The significant attraction toward aqueous proton batteries (APBs) is attributable to their expedited kinetics, elevated safety profile, and economical feasibility. Nevertheless, practical implement significantly blocked by the unsatisfactory energy density due limited cathode materials. Herein, vanadium hexacyanoferrate Prussian blue analog (VOHCF) introduced as a potentially favorable material for APBs. findings demonstrate that this VOHCF electrode exhibits notable reversible capacity of 102.7 mAh g −1 exceptional cycling stability, with 95.4% retention over 10 000 cycles at A . It noteworthy detailed instance being proposed Combining in situ characterization techniques theoretical simulations, origins excellent storage performance are revealed multiple redox mechanisms double active centers ─C≡N group V═O bond well robust structure stability. full cell further achieved coupling diquinoxalino[2,3‐a:2′,3′‐c] phenazine (HATN) anode, demonstrating great potential applications. This work could provide fundamental understanding development feasible materials device.

Manipulating Interfacial Renovation via In Situ Formed Metal Fluoride Heterogeneous Protective Layer toward Exceptional Durable Sodium Metal Anodes

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 5, 2024

Abstract Sodium metal is regarded as an optimal anode material for high‐energy‐density sodium‐ion batteries (SIBs). However, during the processes of sodium deposition and stripping, failure solid electrolyte interphase (SEI) film leads to continuous accumulation inactive sodium, thereby compromising cycling reversibility battery. Here, a novel fluoride heterointerface layer generated constructed through in situ manipulation reaction between TiF 4 Na. The reconstructed NaF/TiF 3 interface layer, which tightly anchors metal, effectively suppresses formation dendrites charge‐discharge process. highly sodium‐philic component exhibits strong binding with Na ions, while NaF reduces + diffusion energy barrier, significantly enhancing kinetics. Due successful artificial construction this Na/TiF composite electrode demonstrates exceptional ultra‐long stability 2370 h symmetric cells (0.5 mAh cm −2 ). Density functional theory (DFT) calculations further validate functionality each protective layer. When paired NaNi 1/3 Fe Mn O 2 cathode pouch cell, it up 2000 cycles at current densities C C, maximum density output 483.1 Wh kg −1 (power density: 320.8 W
