Abstract Rechargeable magnesium‐ion batteries (RMBs) have garnered increasing research interest in the field of post‐lithium‐ion battery technologies owing to their potential for high energy density, enhanced safety, cost‐effectiveness, and material resourcefulness. Despite substantial advancements RMB research, a number intrinsic challenges remain unresolved, such as strong Coulombic interaction between Mg 2+ host crystal structure cathode materials, sluggish diffusion kinetic, poor electrolyte compatibility, formation passivation films on anode interface. These issues hinder commercial applications RMBs. This review provides comprehensive overview progress key areas including representative storage cathode/anode materials conducting electrolytes. Additionally, recent developments electrode‐electrolyte interface regulations pouch‐cell fabrication are outlined, highlighting current implementation effective solutions. Finally, future directions proposed guide development high‐performance RMBs with practical applications.

Rechargeable magnesium batteries (RMBs) have garnered significant attention for their potential in large-scale energy storage applications. However, the commercial development of RMBs has been severely hampered by rapid failure large-sized Mg metal anodes, especially under fast and deep cycling conditions. Herein, a concept proof involving ion-reinforced phytic acid (PA) layer (100 cm × 7.5 cm) with an excellent water-oxygen tolerance, high Mg2+ conductivity, favorable electrochemical stability is proposed to enable uniform plating/stripping anode. Guided even distributions flux electric field, as-prepared PA-Al@Mg electrode (5.8 4.5 exhibits no perforation after cycling. Consequently, ultralong lifespan (2400 h at 3 mA cm-2 1 mAh cm-2) current tolerance (300 9 symmetric cell using anode could be achieved. Notably, PA-Al@Mg//Mo6S8 full demonstrates exceptional stability, operating 8000 cycles 5 C capacity retention 99.8%, surpassing that bare (3000 cycles, 74.7%). Moreover, successfully contributes stable pouch (200 750 0.1 C), further confirming its practical utilization. This work provides valuable theoretical insights technological support implementation RMBs.

From Ab Initio to Instrumentation: A Field Guide to Characterizing Multivalent Liquid Electrolytes

Chemical Reviews, Год журнала: 2025, Номер unknown

Опубликована: Март 10, 2025

In this field guide, we outline empirical and theory-based approaches to characterize the fundamental properties of liquid multivalent-ion battery electrolytes, including (i) structure chemistry, (ii) transport, (iii) electrochemical properties. When detailed molecular-scale understanding multivalent electrolyte behavior is insufficient use examples from well-studied lithium-ion electrolytes. recognition that coupling techniques highly effective, but often nontrivial, also highlight recent characterization efforts uncover a more comprehensive nuanced underlying structures, processes, reactions drive performance system-level behavior. We hope insights these discussions will guide design future studies, accelerate development next-generation batteries through modeling with experiments, help avoid pitfalls ensure reproducibility results.

Li-mediated ammonia synthesis is, thus far, the only electrochemical method for heterogeneous decentralized production. The unique selectivity of solid electrode provides an alternative to one largest thermal catalytic processes. However, it is burdened with intrinsic energy losses, operating at a Li plating potential. In this work, we survey periodic table understand fundamental features that make stand out. Through density functional theory calculations and experimentation on chemistries analogous lithium (e.g., Na, Mg, Ca), find in several ways. It combines stable nitride readily decomposes ideal electrolyte interphase, balancing reagents reactive interface. We propose descriptors based simulated formation binding energies key intermediates further hard soft acids bases (HSAB principle) generalize such features. will help community toward systems beyond nitrogen fixation.
