Crystalline iceplant-like nano-NaVPO4F@graphene as an intercalation-type anode material for sodium-ion batteries

Chem Commun (Camb). 2020 Feb 25;56(16):2479-2482. doi: 10.1039/c9cc08225e.

Abstract

A crystalline iceplant-like nano-NaVPO4F@graphene composite is successfully synthesized by a freeze-drying process. Graphene forms a lamellar structure wherein NaVPO4F nanoparticles are uniformly adhered to the surface of graphene. The composite displays an intercalation-type reaction mechanism and excellent cycling and rate performance.
