由于钠资源储量丰富且价格低廉,钠离子电池(SIBs)可作为锂离子电池(LIBs)的有效替代品已成为共识.基于此,开发适合钠存储的电极材料是钠离子电池发展的关键.近年来,二维层状过渡金属硫属化物在能源和环境领域受到广泛关注.其中MoSe_(2),由于其宽的层间距和较高电导率,被认为是一种具有潜力的SIBs负极材料.本工作中,我们通过静电纺丝,硒化及碳化过程,设计制造了具有多通道电子传输路径的氮掺杂双碳壳层MoSe_(2)纳米材料(MoSe_(2)/MCFs@NC).此结构具有三维连通的导电网络,丰富的空隙和足够的电子传输路径,有助于适应钠离子脱嵌带来的体积膨胀应力,并加快电荷转移动力学.作为钠离子电池负极材料时,MoSe/MCFs@NC表现出高的比容量(10 A g^(-1)电流密度下为319 mA h g^(-1))和优异的循环稳定性(10 A g^(-1)的电流密度下可循环1100圈).此外,该材料在与Na_(3)V_(2)(PO_(4))_(2)O_(2)F正极材料组成的钠离子全电池中也表现出了卓越的性能.理论计算进一步验证了双碳壳层和MoSe之间的强相互作用,对于提升MoSe_(2)/MCFs@NC的钠离子电池综合性能具有重要意义.本研究为制备高性能钠离子电池电极材料提供了新思路.
