Hierarchical Na₃V₂(PO₄)₂F₃ Microsphere Cathodes for High-Temperature Li-Ion Battery Application.

ABSTRACT: Sodium superionic conductor (NASICON)-structured Na₃V₂(PO₄)₂F₃ cathode materials have received vast attention in the high-temperature storage performance due to their structural and thermal stability. Herein, hierarchical Na₃V₂(PO₄)₂F₃ microspheres (NVPF-HMSs) consisting of nanocubes were designed by a one-pot facial solvothermal method. The hierarchical Na₃V₂(PO₄)₂F₃ microsphere size is 2-3 μm, which is corroborated by FE-SEM and HR-TEM analyses. The NVPF-HMSs have been demonstrated as a cathode in Li-ion batteries at both low and elevated temperatures (25 and 55 °C, respectively). The NVPF-HMS cathode in a Li-ion cell exhibit
