Boosting Structural Reversibility of Na3V2(PO4)3 Cathode via Ti-Cr-Al Synergistic Substitution: From Two-Phase to Quasi-Solid-Solution Reaction in Aqueous Sodium-Ion Storage.
Aqueous sodium-ion batteries (ASIBs) are considered promising candidates for large-scale energy storage due to the natural abundance and low cost of sodium. However, the practical application of NASICON-type Na3V2(PO4)3 (NVP) cathodes in aqueous electrolytes is severely hindered by structural degradation and material d...
