要旨

Magnesium rechargeable batteries (Mg batteries) are currently attracting attention as high-energy and low-cost energy storage devices that can replace lithium-ion batteries. Within this context, V2(PO4)3 is a promising material for high-voltage and high-rate cathodes for Mg batteries. However, the strong electrostatic attraction between Mg2+and anions degrades the Mg2+ diffusion in the solid-state of the cathode, which hinders the room-temperature operation. Furthermore, the detailed charge–discharge mechanism of V2(PO4)3 during Mg2+ insertion/extraction is not yet fully understood. Here, we synthesized V2(PO4)3 nanocrystals (50 nm), which are highly dispersed and directly embedded in conductive carbon, for realizing ultrafast cathode reaction for Mg batteries. The V2(PO4)3/carbon composite exhibited a high capacity of 210 mA h g−1 (at 1C-rate) and 110 mA h g−1 (at 10C-rate, i.e., under ultrafast conditions) during Mg2+ insertion/extraction even at room temperature. The phase transition and valence change of vanadium in MgxV2(PO4)3 were evaluated by in situ X-ray diffraction (XRD) and X-ray absorption fine structure (XAFS) analyses. Both in situ measurements revealed that Mg2+ insertion/extraction of MgxV2(PO4)3 (0.5 ≤ x ≤ 1.3) proceeds reversibly with a valence change of vanadium through a solid-solution reaction, unlike the Li+ insertion/extraction of LixV2(PO4)3 (1 ≤ x ≤ 3) via a two-phase reaction. Our findings provide a promising synthesis method of V2(PO4)3 for ultrafast and high-voltage cathodes for practical Mg batteries and experimental evidence for a unique charge–discharge mechanism in MgxV2(PO4)3.

Journal of Materials Chemistry A, B & C cover high quality studies across all fields of materials chemistry. The journals focus on those theoretical or experimental studies that report new understanding, applications, properties and synthesis of materials. The journals have a strong history of publishing quality reports of interest to interdisciplinary communities and providing an efficient and rigorous service through peer review and publication. The journals are led by an international team of Editors-in-Chief and Associate Editors who are all active researchers in their fields. Journal of Materials Chemistry A, B & C are separated by the intended application of the material studied. Broadly, applications in energy and sustainability are of interest to Journal of Materials Chemistry A, applications in biology and medicine are of interest to Journal of Materials Chemistry B, and applications in optical, magnetic and electronic devices are of interest to Journal of Materials Chemistry C. More than one Journal of Materials Chemistry journal may be suitable for certain fields and researchers are encouraged to submit their paper to the journal that they feel best fits for their particular article. Example topic areas within the scope of Journal of Materials Chemistry A are listed below. This list is neither exhaustive nor exclusive. Artificial photosynthesis Batteries Carbon dioxide conversion Catalysis Fuel cells Gas capture/separation/storage Green/sustainable materials Hydrogen generation Hydrogen storage Photocatalysis Photovoltaics Self-cleaning materials Self-healing materials Sensors Supercapacitors Thermoelectrics Water splitting Water treatment
