چکیده
As typical solid-state electrolytes (SSEs), Na1+xZr2SixP3?xO12 NASICONs provide an ideal platform for batteries (SSBs) that display higher safety and accommodate energy densities. The critical points achieving SSBs with efficiencies are to improve essentially the ionic conductivity reduce largely interfacial resistance between SSEs cathode materials, which would necessitate extremely high level of craftsmanship high-pressure equipment. An alternative higher-performance lower-cost is additive manufacturing. Here, we report on effective additive, MgF2, was used in synthesizing NASICONs, resulting fewer defects performance. With addition mere 1 wt% MgF2 total room-temperature NASICON electrolyte reaches up 2.03 mS cm?1, improved ? 181.3%, activation 0.277 eV. Meanwhile, stability Na plating/stripping behavior symmetric cells increases from 236 654 h. We tried reveal microscopic origins MgF2-doped by comprehensive in-house characterizations. Our study discovers a novel provides efficient way prepare SSEs, making it possible fabricate industries.
