Tunnel/P2 Interlocking Structure Coupled with TiO2 Interface Modification for Synergistically Enhanced Structural Stability of Sodium-Ion Battery Cathodes
Layered Mn-based oxides are promising cathode materials for sodium-ion batteries, which are prone to an irreversible P2-O2 phase transition during cycling and thus exhibit poor cyclic stability. Although tunnel-type Mn-based oxides feature a stable structure, they deliver a low sodium storage capacity. In this work,...
