In this study, a NASICON-type Na3Zr2Si2PO12 (NZSP) ceramic filler was prepared using the sol-gel method and then a polymer-integrated solid electrolyte consisting of polyethylene oxide (PEO), NZSP, and sodium perborate (SPB) was prepared by Stokes' solution casting process. Through physico-chemical and electrochemical characterization techniques, the morphology, electrochemical, and thermal properties of the prepared solid electrolyte sample were carefully studied. The PEO/NZSP/SPB electrolyte developed for all-solid-state sodium-ion batteries (ASSSBs) exhibited a strong ionic conductivity, a large window for electrochemical stability, and was effective in controlling the growth of sodium dendrites. Furthermore, the polymer-integrated solid electrolyte showed impressive rate capability, high discharge capacity (73.2 mAh g-1) at 0.1 mA cm-2, and good faradaic efficiency (98%) even after 100 cycles. These results reveal that the PEO/NZSP/SPB electrolyte is a potential and inevitable candidate for the evolution of high-performance rechargeable ASSSBs.eninfo:eu-repo/semantics/closedAccessAll-Solid-State Sodium-İon BatteryNASICONPolyethylene OxidePolymer-İntegrated Solid ElectrolyteSodium PerborateArticle64112WOS:0012225313000012-s2.0-85193242352N/A10.1002/est2.636Q3
