Low-valence Sn2+-doped Na3V2(PO4)3 cathodes: A highly stable cathode for long-cycle-life sodium-ion batteries.
Owing to its high operating voltage and stable three-dimensional Na+ diffusion channels, Na3V2(PO4)3, a typical NASICON-type materials, has attracted a surge of interest for successfully configuring long-term ultra-stable sodium-ion batteries. However, the practical implementation of Na3V2(PO4)3 is severely impeded by...
