About An all-solid state nasicon sodium battery operating at 200 c

Abstract An all-solid state symmetric monolithic sodium ion battery operating at 200 °C is described, using NASICON-type electrodes and electrolyte. Na 3 V 2 (PO 4 ) 3 is used at both electrodes as the active material while Na 3 Zr 2 Si 2 PO 12 stands the role of the Na + solid electrolyte.

We reported here on the electrochemical performances of an all-solid state monolithic symmetric NASICON-based sodium ion battery, assembled by the SPS technique, operating at 200 °C.

Sodium-ion batteries (SIBs) have attracted considerable research interest over the past decades as a promising alternative to lithium-ion batteries (LIBs) because of the greater natural abundance of sodium (∼2.6% in the Earth’s crust), lower raw material costs (∼30–40% less), and an improved safety profile. (1−5) Growing .

Considering both the economic and geopolitical distribution of Li-ion battery components, Na-ion technologies show significant advantages for the next-generation energy storage technologies. As can be seen from the figure, sodium, as an alternative alkali metal, is widely available and equally distributed across the globe.

Thanks to a new experimental set-up, we report for the first time the electrochemical characteristics of an all-solid state Na-ion battery at temperatures as high as 200°C 8.
