Sodium battery with ceramic electrolyte |
摘要 |
The present invention relates to a sodium-ion battery comprising a positive electrode compartment comprising a positive electrode, said positive electrode comprising a Na-insertion compound; a negative electrode compartment comprising a negative electrode, said negative electrode comprising metallic sodium; and an electrolyte composition comprising a solid sodium-ion conductive ceramic electrolyte and a catholyte comprising a metallic salt with formula MY, wherein M is a cation selected from an alkali metal and an alkali-earth metal; and Y is an anion selected from [R 1 SO 2 NSO 2 R 2 ], CF 3 SO 3 - , C(CN) 3 - , B(C 2 O 4 ) 2 - and BF 2 (C 2 O 4 ) - , wherein R 1 and R 2 are independently selected from fluorine or a fluoroalkyl group. The device is able to operate below the melting point of the anode component. |
