“…8 Hence attempts to obtain it with large quantity and good quality remain a hurdle to experimentally test this material in Mg cell. Although CF-MnO 2 showed interesting properties as Li-ion and Na-ion battery cathode, 38,39 its performance in rMB remains to be explored. R-MnO 2 and α-MnO 2 are both classical intercalation-type cathodes in Li-ion battery.…”

Despite tremendous efforts denoted to magnesium battery research, the realization of magnesium battery is still challenged by the lack of cathode candidate with high energy density, rate capability and good recyclability. This situation can be largely attributed to the failure to achieve sustainable magnesium intercalation chemistry. In current work we explored the magnesiation of distinct MnO2 polymorphs using first-principles calculations, focusing on providing quantitative analysis about the feasibility of magnesium intercalation. Consistent with experimental observations, we predicted that ramsdellite-MnO2 and α-MnO2 are conversion-type cathodes while nanosized spinel-MnO2 and MnO2 isostructual to CaFe2O4 are better candidates for Mg intercalation. Key properties that restrict Mg intercalation include not only sluggish Mg migration but also stronger distortion that damages structure integrity and undesirable conversion reaction. We demonstrate that by evaluating the reaction free energy, structural deformation associated with the insertion of magnesium, and the diffusion barriers, a quantitative evaluation about the feasibility of magnesium intercalation can be well established. Although our current work focuses on the study of MnO2 polymorphs, the same evaluation can be applied to other cathode candidates, thus paving the road to identify better cathode candidates in future.

“…These materials usually shows a high tap density and unexpected electrochemical performance when used as electrode materials. 21,22 A recent report indicated the high sodium mobility and structure stability in the post-spinel phase. 23 A black powder sample, which was NaMn 2 O 4 , was synthesized under high pressure using Na 2 O 2 and Mn 2 O 3 as starting materials.…”

High-pressure synthesized quasi-one-dimensional NaMn 2 O 4 and Li 0.92 Mn 2 O 4 are both antiferromagnetic insulators. Here their atomic and magnetic structures are investigated using neutron powder diffraction. The present crystal structural analyses of NaMn 2 O 4 reveal that a Mn 3+ /Mn 4+ charge-ordering state exists even at low temperature (down to 1.5 K). It is evident that one of the Mn sites shows a strongly distorted Mn 3+ octahedron due to the Jahn-Teller effect. Above T N = 35 K, a two-dimensional short-range correlation is observed, as indicated by asymmetric diffuse scattering. Below T N , two antiferromagnetic transitions are observed: (i) a commensurate long-range Mn 3+ spin ordering below T N1 = 35 K and (ii) an incommensurate Mn 4+ spin ordering below T N2 = 11 K. Surprisingly, the two antiferromagnetic orders are found to be independent of each other. The commensurate magnetic structure (k C = 0.5, 0.5, 0.5) follows the magnetic anisotropy of the local easy axes of Mn 3+ , while the incommensurate Mn 4+ one shows a spin-density-wave or a cycloidal order with k IC = (0, 0, 0.216). For Li 0.92 Mn 2 O 4 , on the other hand, the absence of a long-range spin-ordered state is confirmed down to 1.5 K.
