“…When we consider the sodium metal oxide compounds, there are similar structural properties with Li compounds such as LiCoO 2 , NaCoO 2 , etc. [2,3] Although the produced Na-ion battery cells have a similar voltage window, capacity, etc., there are some disadvantages compared to Li-ion cells such as lower energy density, larger ionic radii, higher mass, etc. [4,5] The disadvantages become less significant when large energy storage systems such as stationary systems, etc.…”

“…[9] It is seen that the P2 phase is more stable in air and has better cyclic stability than the O3 structure. [2,10] It is seen that vanadium-based electrode materials have been studied in recent years. The O3-NaVO 2 and P2-Na x VO 2 (or their phosphates) were investigated by the substitutions of Zn, Cu, Fe, Co, and Ti which show better battery performance.…”

The Na0.67Mn0.5−xVxFe0.43Al0.07O2 (x = 0–0.1) samples are successfully produced and their structural properties are investigated by common techniques. The highest surface area is found as 4.94 m2 g−1 for x = 0.04 V by the Brunauer–Elmet–Teller analysis. According to X‐ray photoelectron spectroscopy of x = 0.04 V‐doped sample,V4+, and V5+ ions are formed in the structure. The main phase is observed as P63/mmc symmetry with an impurity phase of V6O13 for x ≥ 0.06 . According to the CV analysis, while the redox voltage decreases for the Mn3+/Mn4+ , the intensity of the peaks of Fe2+/Fe3+ redox reaction decreases. While the best capacity value of the half cells at C/3‐rate is obtained as 171 mAh g−1 for x = 0.04, the lowest capacity fade is found for x = 0.08 . It is mentioned the V6O13 may contribute to the electrochemical process . The galvanostatic tests are investigated for the voltage windows of 3.5–1.5, 4–1.5, 4–2.5, 4–2, and 4–2.5 V and it is seen that the battery cells for 3.5–1.5 V have the best capacity fade (6%) among the others. The Na0.67Mn0.46V0.04Fe0.43Al0.07O2/ hard carbon is used for the full cells with presodiated anode and the first capacity value of the full cell is obtained as 80.2 mAh g−1 for C/2‐rate.

Sodium‐ion batteries (SIBs), recognized for balanced energy density and cost‐effectiveness, are positioned as a promising complement to lithium‐ion batteries (LIBs) and a substitute for lead–acid batteries, particularly in low‐speed electric vehicles and large‐scale energy storage. Despite their extensive potential, concerns about range anxiety due to lower energy density underscore the importance of fast‐charging technologies, which drives the exploration of high‐rate electrode materials. Polyanionic cathode materials are emerging as promising candidates in this regard. However, their intrinsic limitation in electronic conductivity poses challenges for synchronized electron and ion transport, hindering their suitability for fast‐charging applications. This review provides a comprehensive analysis of sodium ion migration during charging/discharging, highlighting it as a critical rate‐limiting step for fast charging. By delving into intrinsic dynamics, key factors that constrain fast‐charging characteristics are identified and summarized. Innovative modification routes are then introduced, with a focus on shortening migration paths and increasing diffusion coefficients, providing detailed insights into feasible strategies. Moreover, the discussion extends beyond half cells to full cells, addressing challenges and opportunities in transitioning polyanionic materials from the laboratory to practical applications. This review aims to offer valuable insights into the development of high‐rate polyanionic cathodes, acknowledging their pivotal role in advancing fast‐charging SIBs.
