High-rate performance magnesium batteries achieved by direct growth of honeycomb-like V2O5 electrodes with rich oxygen vacancies

Dongzheng Wu et al.

Summary: This study proposes a dual-functional design of V2O5 electrode with a rational honeycomb-like structure and rich oxygen vacancies to enhance the kinetics synergistically. The results demonstrate that the oxygen vacancies can enhance both the intrinsic electronic conductivity of V2O5 and the Mg2+ diffusion kinetics inside the cathode, resulting in good high-rate performance.

Surface-redox sodium-ion storage in anatase titanium oxide

Qiulong Wei et al.

Summary: Sodium-ion storage technologies are considered promising for large-scale grid systems due to the abundance and low cost of sodium. However, the mechanism of sodium-ion storage is still relatively unexplored compared to lithium-ion storage. In this study, the sodium-ion storage properties of anatase titanium dioxide (TiO2(A)) are systematically determined. The amorphous layer formed during the sodiation process and the size of TiO2(A) nanoparticles play important roles in achieving high specific capacity. The surface-redox mechanism of TiO2(A) nanoparticles results in excellent rate capability, cycling stability, and low overpotentials, showing great potential for high-power sodium-ion storage.

Rational design of artificial interphase buffer layer with 3D porous channel for uniform deposition in magnesium metal anodes

Tiantian Wen et al.

Summary: A facile and effective approach to stabilize the magnesium (Mg) metal anode with artificial solid-electrolyte interphase (SEI) layers has been developed in this study. The 3D porous channel structure of the interfacial phytic acid (PA) skeleton regulates ion flux, homogenizes the distribution of Mg2+, and triggers uniform plating/stripping of Mg. This advanced strategy for modulating Mg2+ transport addresses the basic challenges for rechargeable magnesium metal batteries (RMBs).

High-Energy Aqueous Magnesium Ion Batteries with Capacity-Compensation Evolved from Dynamic Copper Ion Redox

Shuxin Zhang et al.

Summary: A superior aqueous electrolyte with a copper foam interlayer between anode and separator is proposed to solve the challenges of low specific capacity and low voltage plateau in magnesium ion batteries (MIBs). The redox of copper ions weakens the solvation of Mg2+ cations in the electrolyte and enhances electronic conductivity of the anode, offering effective capacity-compensation to PTCDI-Mg conversion reactions during long-term cycles. As a result, MIBs using expanded graphite cathode coupled with PTCDI anode demonstrate exceptional performance with ultra-high capacity and excellent cycling stability.

Polyaniline nanoarrays/carbon cloth as binder-free and flexible cathode for magnesium ion batteries

Ping Luo et al.

Summary: Magnesium ion batteries have attracted attention for their high theoretical capacity and low cost. However, the slow diffusion rate caused by the strong polarization effect of Mg2+ has hindered their development. In this study, a binder-free polyaniline array/carbon cloth cathode was designed and synthesized for improved electrochemical performance in MIBs.

Basal Planes Unlocking and Interlayer Engineering Endows Proton Doped-MoO2.8F0.2 with Fast and Stable Magnesium Storage

Weixiao Wang et al.

Summary: This research introduces F- substitution and H+ interstitial doping to improve the performance of molybdenum trioxide as a cathode material for rechargeable magnesium batteries. F- substitutional doping unlocks the inactive basal plane and accelerates ion diffusion, while H+ interstitial doping expands interlayer spacing and stabilizes the structure. Dual doping creates shallow impurity levels, facilitating electron transport. The HMoOF electrode exhibits excellent reversible capacity, rate capability, and cycling stability in RMBs.
