“…When coupled with a hard carbon anode, it delivers a high reversible capacity of 313 mAh g −1 with 79% initial Coulombic efficiency. Besides, a series of other metal‐doped Mn/Fe‐based oxides have also been extensively researched and have shown promising electrochemical performance, such as P2‐Na 2/3 Mn 0.8 Fe 0.1 Ti 0.1 O 2 , 118 P2‐Na 0.67 Li 0.1 Fe 0.4 Mn 0.5 O 2 , 119 O3‐NaCo 1/3 Fe 1/3 Mn 1/3 O 2 , 120 and P2/O3 biphase Na 0.67 Fe 0.425 Mn 0.425 Mg 0.15 O 2 121 …”

Sodium‐ion batteries (SIBs), which are an alternative to lithium‐ion batteries (LIBs), have attracted increasing attention due to their low cost of Na resources and similar Na storage mechanism to LIBs. Compared with anode materials and electrolytes, the development of cathode materials lags behind. Therefore, the key to improving the specific energy and promoting the application of SIBs is to develop high‐performance sodium intercalation cathode materials. Transition‐metal oxides are one of the most promising cathode materials for SIBs owing to their excellent energy density, high specific discharge capacity, and environmentally friendly nature. In the present work, the latest progress in the research of transition‐metal oxides is summarized. Moreover, the existing challenges are discussed, and a series of strategies are proposed to overcome these drawbacks. This review aims at providing guidance for the development of metal oxides in the next stage.

“…Whereas the O3 phase normally displays a higher capacity on the initial charge due to the higher Na content. 17 The structural evolution of electrode materials during cycling provides valuable information about battery failure mechanisms. Upon charging, Na removal destabilises the structure resulting in rearrangement or layer gliding and in some cases phase transformation.…”

“…Other elements such as Mg, Al, and Nb have also been explored as dopants to overcome the capacity fading issues of FeÀ Mn binary cathodes. [135][136][137][138][139] Al-doping could slightly increase the electrical conductivity and Na-ion diffusivity of O3-type NaFe 0.5 Mn 0.5 O 2 . However, negligible improvements on the kinetics and stabilities of the electrochemical reaction were observed.…”
