An organic-inorganic composite polymer electrolyte (CPE) was constructed via introducing an active filler of Na-β''-Al2O3 into a solid-state polymer electrolyte (SPE) composed of poly(ethylene oxide) (PEO) and sodium bis(trifluoromethanesulfonyl)-imide (NaTFSI). The phase composition, ionic conductivity, Na+ transference number, and electrochemical stability were investigated. The electrochemical properties of SPE and CPE in Na|Na3V2(PO4)3@C solid-state sodium batteries were obtained. The results show that the CPE has a greater Na+ transference number of 0.71 than SPE (i.e., 0.19) and a higher Na+ conductivity of 8.19×10-4 S/cm than SPE (i.e., 1.65×10-4 S/cm) at 80 ℃. The CPE exhibits a superior cycling stability with capacity retentions of 93.9% after 100 cycles at 0.5 C and 74.0% after 500 cycles at 2.0 C in Na|CPE|Na3V2(PO4)3@C solid-state batteries.
