摘要
钒酸铵盐由于具有较高的比容量,通常被用作水性锌离子电池的正极材料。然而,它们较差的效率和速率性能阻碍了它们的广泛应用。为了解决这些问题,我们通过水热技术将锰离子引入(NH4)2V4O9中,制备了(NH4)2V4O9和MnV2O6均匀分布的杂化纳米片(NVM)。结果表明,在NVM作为电极材料时,AZIB具有优异的速率性能、稳定的循环性能和良好的效率特性。在0.1 a·g−1的电流密度下,AZIB具有500 mAh g−1的高比容量。在1 a·g−1电流下,经过100次循环后,其比容量仍保持在350 mAh g−1。在5 A·g−1下,经过1000次循环后,其比容量为140 mAh g−1,保持了98%的初始容量。锰离子的加入降低了电极的扩散阻抗,增加了电极的扩散系数,使电极的电压窗降低到0.13 V。NVM材料的大容量和高能效使得该电池在实际应用中得到了更广泛的应用。
Mn2+-doped (NH4)2V4O9 cathode materials for highly stable aqueous zinc-ion batteries
Due to their high specific capacity, ammonium vanadate salts are commonly utilized as cathode materials for aqueous zinc-ion batteries (AZIBs). However, their inferior efficiency and rate performance have hindered widespread adoption. In order to address these issues, we developed evenly distributed hybrid nanosheets (NVM) of (NH4)2V4O9 and MnV2O6 by introducing manganese ions into (NH4)2V4O9 through the hydrothermal technique. The results show that AZIB exhibits outstanding rate performance, stable cycle performance, and good efficiency characteristics when NVM as electrode materials. The AZIB has a high specific capacity of 500 mAh g−1 at a current density of 0.1 A·g−1. And it maintains a specific capacity of 350 mAh g−1 after 100 cycles at 1 A·g−1. It exhibits good stable cycle performance, the specific capacity is 140 mAh g−1 after 1000 cycles at 5 A·g−1, retaining 98% of its initial capacity. The addition of manganese ions can reduce the electrode’s diffusion impedance and increase its diffusion coefficient, resulting in a lower voltage window of 0.13 V. The large capacity and high energy efficiency of NVM materials make the battery more widely used in practical applications.
