摘要

金属铜价格低廉、反应电位高（0.34 V）、理论比容量高、储量丰富且化学性质稳定，因此在水性电池中是一种前景广阔的阳极。然而，目前仅有少数几种铜离子存储材料被报道。本文首次选择了层状五氧化二钒来储存铜离子。原位 XRD 显示了循环过程中独特的两相转变过程。V2O5 电极显示出稳定的铜离子存储性能。在 1.0 A g-1 的条件下，它的第一个循环可提供 91.9 mAh g-1，循环寿命高达 4000 个循环。这项研究提供了一种令人感兴趣的铜离子存储材料，扩大了铜离子存储电极材料的可选范围。

Achieving Stable Copper Ion Storage in Layered Vanadium Pentoxide

Copper metal is a promising anode in aqueous batteries due to its low price, noble reaction potential (0.34 V), high theoretical specific capacity, abundance and chemical stability. However, only a few copper ion storage materials have been reported. Herein, layered vanadium pentoxide is chosen to store copper ions for the first time. Ex situ XRD reveals a unique two phase transition process during cycling. The V2O5 electrode shows stable copper ion storage performance. It delivers 91.9 mAh g−1 for the first cycle with a cycle life of as high as 4000 cycles at 1.0 A g−1. This work provides an intriguing copper ion storage material and expands the available options of electrode materials for copper ion storage.
