Na3V2(PO4)2F3 is one of the most studied polyanion type cathode materials for sodium-ion batteries (SIBs) and offers great promises. However, the inferior rate capability induced by its sluggish diffusion of electrons and ions greatly limits the practical application of electrode materials in SIBs. Herein, we develop an efficient method to fabricate in situ carbon-coated Na3V2(PO4)2F3 nanosheets by using cost-effective amylopectin. The amylopectin not only could induce the nucleation of Na3V2(PO4)2F3 along its backbone to form a 2D nanostructure, but also act as a source of amorphous carbon for in situ coating on the active material surface. The composite exhibits extraordinary rate capability (104 mA h g–1 at 40 C, 51 mA h g–1 at 150 C) and desirable cycling stability. Such satisfactory achievements, especially the superior rate performance, should be ascribed to its unique 2D nanostructure which shortens the Na+ diffusion length, and the in situ carbon coating endows the composites with effective electron transport. Even applied to full cells, the obtained devices still display an exceptionally high energy density (94.8 W h kg–1), high power density (7295 W kg–1), and excellent cyclic stability.

“…One obvious peak at 1070.3 eV for Na 1s can be observed in the pristine state shown in Figure S16 (Supporting Information). [ 52 ] The intensity of this peak reduces distinctly, corresponding to the extraction of Na + from the electrode. This characteristic peak cannot be detected after discharging to 0.4 V, meaning that the Na + insertion behavior is absent.…”

Aqueous zinc ion batteries (AZIBs) have attracted much interest in the next generation of energy storage devices because of their elevated safety and inexpensive price. Polyanionic materials have been considered as underlying cathodes owing to the high voltage, large ionic channels and fast ionic kinetics. However, the low electronic conductivity limits their cycling stability and rate performance. Herein, mesoporous Na3V2(PO4)2F3 (N3VPF) nanocuboids with the size of 80–220 nm cladded by reduced graphene oxide (rGO) have been successfully prepared to form 3D composite (N3VPF@rGO) by a novel and fast microwave hydrothermal with subsequent calcination strategy. The enhanced conductivity, strengthened pseudocapacitive behaviors, enlarged DZn2+, and stable structure guarantee N3VPF@rGO with splendid Zn2+ storage performance, such as high capacity of 126.9 mAh g‐1 at 0.5 C (1 C = 128 mA g‐1), high redox potentials at 1.48/1.57 V, high rate capacity of 93.9 mAh g‐1 at 20 C (short charging time of 3 mins) and extreme cycling stability with capacity decay of 0.0074% per cycle after 5000 cycles at 15 C. The soft package batteries also present preeminent performance, demonstrating the practical application values. In situ X‐ray diffraction, ex situ transmission electron microscopy and X‐ray photoelectron spectroscopy reveal a reversible Zn2+ insertion/extraction mechanism.
