Popis: A sodium secondary battery has been constructed by using a nonvolatile and nonflammable Na[FSA]-[C(3)C(1)pyrr][FSA] (FSA = bis(fluorosulfonyl)amide, C(3)C(1)pyrr = N-methyl-N-propylpyrrolidinium) ionic liquid, a NaCrO(2) positive electrode and a Na metal negative electrode. The charge-discharge performance is evaluated over a wide temperature range of −20–90℃. It has been demonstrated that the sodium secondary battery has long cycle lives both at a high temperature of 90℃ and at a low temperature of 0℃. Thus, the ionic liquid-based sodium secondary battery is expected to be a viable alternative to lithium ion battery for many applications.
