开发高容量、高倍率性能的新型钒酸锰电极材料是一个巨大的挑战。在这项工作中，一种新的锰钒酸盐生长在还原氧化石墨烯成功地通过一种快速和简便的方法。小的Mn2.1V0.9O4颗粒（20-50 nm）锚定在还原的氧化石墨烯上，这显著地减小了体积变化并改善了导电性和锂离子转移。此外，Mn 2. 1V 0. 9 O 4与还原后的氧化石墨烯之间存在较强的化学相互作用，有利于加速电荷转移。这些特征有利于实现高可逆容量和优异的倍率性能。作为锂离子电池的负极，在100 mA g−1下循环80次后仍保持981 mA h g− 1的高放电容量。即使在2000 mA g−1时，也可实现748 mA h g− 1的高容量。该工作为钒酸锰材料的合成和潜在应用带来了新的前景。
The development of novel manganese vanadate electrode materials with high capacity and good rate capability is a great challenge. In this work, a novel manganese vanadate grown on reduced graphene oxide is successfully prepared by a fast and facile approach. Small Mn2.1V0.9O4particles (20–50 nm) are anchored on reduced graphene oxide, which significantly alleviates volume changes and improves electrical conductivity and lithium ion transfer. In addition, the strong chemical interactions between Mn2.1V0.9O4and reduced graphene oxide are conducive to accelerate charge transfer. These features are favorable for achieving high reversible capacity and excellent rate performance. As an anode for lithium-ion batteries, a high discharge capacity of 981 mA h g−1is retained after 80 cycles at 100 mA g−1. Even at 2000 mA g−1, a high capacity of 748 mA h g−1is achieved. New prospects are brought by this work for the synthesis and the potential application of manganese vanadate materials.
