Low-Cost Raw Materials Synthesized Na2.9375PS3.9375Cl0.0625 Solid Electrolyte
Na 3 PS 4 -based materials, which have relatively high conductivities, make promising Na-ion solid electrolytes for realizing all-solid-state sodium batteries. Herein, Na 2.9375 PS 3.9375 Cl 0.0625 solid electrolytes’ power is prepared by a mechanical ball milling process and subsequent heat treatment process using low-cost Na, NaCl, P 2 S 5 , and S as raw materials. In addition, its electrical conductivity and electrochemical performance by compounding with polyethylene oxide–NaClO 4 are studied. The results show that Na 2.9375 PS 3.9375 Cl 0.0625 solid electrolyte heated at 550 °C with polyethylene oxide–NaClO 4 exhibits Na-ion conductivity of 8.75 × 10 −4 S cm −1 . The pragmatic and cost-effective raw materials grant the solid electrolyte with high-performance and higher practical value.
