As electrolytes for sodium secondary batteries operating over a wide temperature range, Na[FSA]-[C sub(3)C sub(1)pyrr][FSA] (FSA = bis(fluorosulfonyl)amide, C sub(3)C sub(1)pyrr = N-methyl-N-propylpyrrolidinium) ionic liquids have been investigated. The effects of Na ion concentration (0-60 mol% Na[...
