Pentavalent Ta-substitution significantly enhances ionic conductivity
Critical current density shows improvements with dopants
Different dopants yield varying effects on battery performance

Abstract

NASICON-type materials are promising electrolytes for all-solid-state sodium-ion batteries (ASSSBs); however, the role of pentavalent dopants (V 5+ , Nb 5+ and Ta 5+ ) in Na 3 Zr 2 Si 2 PO 12 (NZSP) remains insufficiently understood.
