Defect-Induced Dense Amorphous/Crystalline Heterophase Enables High-Rate and Ultrastable Sodium Storage.

ABSTRACT: Currently, the construction of amorphous/crystalline (A/C) heterophase has become an advanced strategy to modulate electronic and/or ionic behaviors and promote structural stability due to their concerted advantages. However, their different kinetics limit the synergistic effect. Further, their interaction functions and underlying mechanisms remain unclear. Here, a unique engineered defect-rich V₂ O₃ heterophase structure (donated as A/C-V₂ O_{3- x} @C-HMCS) composed of mesoporous oxygen-deficient amorphous _- hollow core (A-V₂ O_{3- x} /HMC) and lattice-distorted crystalline shell (C-V₂ O₃ /S) encapsulated by carbon is rationally designed via a facile approach.
