“…[106] Iron doping of nanostructured spinels Mg x Mn 2 O 4 is a beneficial for the improvement of their Na storage performance due to the dual role of Mg and Fe ions: although Mg 2 + ions stabilize the spinel structure; iron dopants reduce the electrolyte decomposition. [107] Owing to the "zero-strain" properties, Li 4 Ti 5 O 12 (LTO) is capable of feasible Li/Mg co-intercalation confirmed by both density functional theory (DFT) calculations and experiments. Wu et al have established that the combination of lithiation and magnesiation in large-sized LTO electrodes (particles larger than 100 nm) is strongly dependent on the LiCl concentration in the dual Li/Mg electrolytes, the minimum concentration being 0.05 m. [108] By tuning the salt concentrations in the dual electrolyte, significant improvements in the electrochemical performance of LTO in comparison with pure Mg electrolyte have been reported.…”

To outline the role of dual‐ion intercalation chemistry to reach sustainable energy storage, the present Review aimed to compare two types of batteries: widely accepted dual‐ion batteries based on cationic and anionic co‐intercalation versus newly emerged hybrid metal‐ion batteries using the co‐intercalation of cations only. Among different charge carrier cations, the focus was on the materials able to co‐intercalate monovalent ions (such Li+ and Na+, Li+ and K+, Na+ and K+, etc.) or couples of mono‐ and multivalent ions (Li+ and Mg2+, Na+ and Mg2+, Na+ and Zn2+, H+ and Zn2+, etc.). Furthermore, the Review was directed on co‐intercalation materials composed of environmentally benign and low‐cost transition metals (e. g., Mn, Fe, etc.). The effect of the electrolyte on the co‐intercalation properties was also discussed. The summarized knowledge on dual‐ion energy storage could stimulate further research so that the hybrid metal‐ion batteries become feasible in near future.

“…For the AMn 2 O 4 spinel (A = Li, Na or Mg), Kolli and Van der Ven assumed that small cations (Li + and Mg 2+ ) prefer to occupy the tetrahedral site, while larger Na + prefers to occupy the octahedral site (16c) [14]. Recent theoretical calculations on the intercalation of sodium into λ-MnO 2 unveiled that initially the occupation of the tetrahedral site by sodium is energetically more favorable than the octahedral site for the composition Na 0.125 Mn 2 O 4 [15]. The calculated insertion voltage is 2.85 V, and the lattice cell would expand upon sodium intercalation.…”

After more than 30 years of delay compared to lithium-ion batteries, sodium analogs are now emerging in the market. This is a result of the concerns regarding sustainability and production costs of the former, as well as issues related to safety and toxicity. Electrode materials for the new sodium-ion batteries may contain available and sustainable elements such as sodium itself, as well as iron or manganese, while eliminating the common cobalt cathode compounds and copper anode current collectors for lithium-ion batteries. The multiple oxidation states, abundance, and availability of manganese favor its use, as it was shown early on for primary batteries. Regarding structural considerations, an extraordinarily successful group of cathode materials are layered oxides of sodium, and transition metals, with manganese being the major component. However, other technologies point towards Prussian blue analogs, NASICON-related phosphates, and fluorophosphates. The role of manganese in these structural families and other oxide or halide compounds has until now not been fully explored. In this direction, the present review paper deals with the different Mn-containing solids with a non-layered structure already evaluated. The study aims to systematize the current knowledge on this topic and highlight new possibilities for further study, such as the concept of entatic state applied to electrodes.

Sodium manganese‐based oxides (NMO) are attracting huge attention as safe and cost‐effective cathode materials for sodium‐ion batteries (SIBs). To date, one of the most important challenges of NMO‐based cathodes is the relatively low capacity. Therefore, it is of great significance to develop high‐capacity NMO‐based cathodes. Great efforts have been made to enhance the reversible capacity of NMO‐based cathodes, achieving considerable progress not only on electrochemical performance, but also the mechanism of massive sodium ion storage. In this paper, the structure and sodium storage mechanism for typical phases of NMO are reviewed, including P2, P3, O3, tunnel‐type, and spinel‐type NMO‐based cathodes. Strategies for high‐capacity NMO‐based cathodes, such as cationic substitution, anion redox activation, etc are introduced in detail. Last but not least, the future opportunities and challenges for high‐capacity NMO‐based cathode are prospected.
