Rational design of a tunnel-monoclinic intergrowth cathode based on surface energy chemistry modulation for sodium-ion batteries
The tunnel-type oxide cathode material Na0.44MnO2 (NMO) and the sodium-based ferricyanide NaxMn[Fe(CN)6]1−δ·nH2O (FMHCF) are considered among the most promising cathode materials for sodium-ion batteries. However, the poor structural stability of FMHCF and the low sodium content in the NMO cathode limit their practical...
