Al-contaminated Ta-substituted Li7La3Zr2O12 (LLZ:Ta), synthesized via solid-state reaction, and Al-free Li7La3Zr2O12, fabricated by hot-press sintering (HP-LLZ:Ta), have relative densities of 92.7% 99.0%, respectively. Impedance spectra show the total conductivity LLZ:Ta to be 0.71 mS cm–1 at 30 °C that HP-LLZ:Ta 1.18 cm–1. The lower for than was attributed higher grain boundary resistance density LLZ:Ta, as confirmed their microstructures. Constant direct current measurements with a 0.5 mA...
As possible electrolyte materials for all-solid-state Na-ion batteries (NIBs), scandium-substituted Na3Zr2(SiO4)2(PO4) in the structure of NASICONs (Na superionic conductors) has received hardly any attention so far, although among all trivalent cations, Sc3+ might be most suitable substitution ion because ionic radius (74.5 pm) is closest to that Zr4+ (72.0 pm). In this study, a solution-assisted solid-state reaction (SASSR) method described, and series with formula...

The lack of suitable candidate electrolyte materials for practical application limits the development all-solid-state Na-ion batteries.
Lithium and sodium (Na) mixed polyanion solid electrolytes for all-solid-state batteries display some of the highest ionic conductivities reported to date. However, effect mixing on ion-transport properties is still not fully understood. Here, we focus Na
Bulk-type SSLB based on LLZ:Ta achieves high specific areal capacity and operational current densities.
Impedance spectroscopy measurements down to very low temperatures allowed for resolving bulk ion transport properties in highly conducting ceramic electrolytes.
Abstract The huge demand for delocalized energy storage due to the application of fluctuating sources leads a need low‐cost devices available on large scale and with high density. Solid‐state sodium batteries (SSNBs) show great potential in this field have recently attracted extensive interest. Several review‐type publications already discussed fundamental materials properties more academic aspects related ionic transport charge transfer. In contrast, current Review uses state‐of‐the‐art...

Abstract Solid‐state sodium batteries (SSNBs) have attracted extensive interest due to their high safety on the cell level, abundant material resources, and low cost. One of major challenges in development SSNBs is suppression dendrites during electrochemical cycling. The solid electrolyte Na 3.4 Zr 2 Si 2.4 P 0.6 O 12 (NZSP) exhibits one best dendrite tolerances all reported electrolytes (SEs), while it also shows interesting growth along surface NZSP rather than through ceramic.
