合理地合成了分散在不同碳基质中的Na3V2(PO4)(3)纳米颗粒，并对其进行了系统的表征。乙炔碳为电子和钠离子提供了最佳的导电网络，使Na3V2(PO4)(3)具有稳定的循环性能和高倍率性能。基于Na3V2(PO4)(3)的对称钠离子电池表现出优异的电化学性能，有望实现大规模、低成本的储能应用。
Na3V2(PO4)(3) nanograins dispersed in different carbon matrices are rationally synthesized and systematically characterized. The acetylene carbon matrix provides the best conductive networks for electrons and sodium ions, which endows Na3V2(PO4)(3) stable cyclability and high rate performance. The Na3V2(PO4)(3)-based symmetric sodium-ion batteries show outstanding electrochemical performance, which is promising for large-scale and low-cost energy storage applications.
