摘要
锌离子电池具有本征安全性、低成本和高倍率特性,是一种极具竞争力的绿色储能装置。层状五氧化二钒(V_(2)O_(5))理论比容量和能量密度高,在优化储锌性能方面具有重要意义。然而,V_(2)O_(5)电子导电率低,在工作过程中,常常会受到电化学性能衰减的困扰。从复合材料、表面包覆、离子掺杂及层间插层四个常用改性方法进行了综述。并对未来促进Zn/V_(2)O_(5)性能提升及应用进行了展望。
Zinc-ion battery is a competitive green energy storage device with intrinsic safety,low cost and high rate.It is a highly competitive green energy storage device.Layered V_(2)O_(5) has high specific capacity and energy density,which is of great significance in optimizing zinc storage performance.However,V_(2)O_(5) has a low electrical conductivity and suffers from performance degradation during charge and discharge process.The commonly used modification methods of V_(2)O_(5) are summarized from four aspects,composite material,surface coating,ion doping and interlayer intercalation.The future performance improvement and application of Zn/V_(2)O_(5) are prospected.
