Room-Temperature All-solid-state Rechargeable Sodium-ion Batteries with a Cl-doped Na(3)PS(4) Superionic Conductor
All-solid-state sodium-ion batteries are promising candidates for large-scale energy storage applications. The key enabler for an all-solid-state architecture is a sodium solid electrolyte that exhibits high Na(+) conductivity at ambient temperatures, as well as excellent phase and electrochemical s...

description | All-solid-state sodium-ion batteries are promising candidates for large-scale energy storage applications. The key enabler for an all-solid-state architecture is a sodium solid electrolyte that exhibits high Na(+) conductivity at ambient temperatures, as well as excellent phase and electrochemical stability. In this work, we present a first-principles-guided discovery and synthesis of a novel Cl-doped tetragonal Na(3)PS(4) (t-Na(3−x)PS(4−x)Cl(x)) solid electrolyte with a room-temperature Na(+) conductivity exceeding 1 mS cm(−1). We demonstrate that an all-solid-state TiS(2)/t-Na(3−x)PS(4−x)Cl(x)/Na cell utilizing this solid electrolyte can be cycled at room-temperature at a rate of C/10 with a capacity of about 80 mAh g(−1) over 10 cycles. We provide evidence from density functional theory calculations that this excellent electrochemical performance is not only due to the high Na(+) conductivity of the solid electrolyte, but also due to the effect that “salting” Na(3)PS(4) has on the formation of an electronically insulating, ionically conducting solid electrolyte interphase. |
