Abstract
A sodium-ion electrochemical cell described herein comprises a cathode, an anode, and a non-aqueous sodium-containing electrolyte therebetween. The electrolyte comprises a sodium salt dissolved in a liquid organic carrier. The cathode comprises at least one transition metal chalcogenide compound in an initial discharged or partially discharged state and having the formula NaMXCl, wherein 0<x≦1; M is at least one transition metal having a +3, +4, or +5 fully discharged oxidation state, i.e., when x is 1. X is at least one chalcogen selected from the group consisting of S and Se, and n is 0 when the discharged oxidation state of M is +3, n is 1 when the discharged oxidation state of M is +4, and n is 2 when the discharged oxidation state of M is +5. In some embodiments, the cathode comprises NaVS, NaTiS, or a combination thereof.
