Abstract

The exploration of solid polymer electrolytes with both superior ionic conductivity and high mechanical stability for sodium-metal batteries still remains dramatical challenges. Herein, we report a composite electrolyte fabricated by sandwiching nanoporous ceramic with a poly(ethylene oxide) (PEO) base polymer electrolyte. This laminated configuration yields superior ionic conductivity of 1.6x 10ˉ⁴ S cmˉ¹ at room temperature, stable Na plating and stripping, as well as wide potential stability window of 4.2 V vs Na/Na+.
