Summary: Aqueous zinc ion batteries (AZIBs) have shown promising potential as next-generation energy storage devices due to their high safety and low cost. However, the low electronic conductivity of polyanionic cathode materials has limited their cycling stability and rate performance. In this study, a 3D composite (N3VPF@rGO) consisting of mesoporous Na3V2(PO4)(2)F-3 nanocuboids cladded by reduced graphene oxide (rGO) was successfully synthesized using a novel microwave hydrothermal and subsequent calcination strategy. The N3VPF@rGO composite exhibited enhanced conductivity, pseudocapacitive behavior, enlarged D-Zn(2+), and stable structure, leading to excellent Zn2+ storage performance, including high capacity, high redox potentials, high rate capacity, and extreme cycling stability. The results also demonstrated the practical application values of the soft package batteries. In situ X-ray diffraction, ex situ transmission electron microscopy, and X-ray photoelectron spectroscopy were employed to investigate the reversible Zn2+ insertion/extraction mechanism.
