An asymmetric bilayer polymer-ceramic solid electrolyte for high-performance sodium metal batteries
文献摘要:
Manufacturing an excellent solid electrolyte compatible with a high-voltage cathode is viewed as a crit-ical tactic for improving the energy density of solid-state sodium-ion batteries(SSIBs).A novel asymmet-ric bilayer solid electrolyte of the PEO-SN-NaClO4|NZSP-NSO with an anti-reduction PEO-SN-NaClO4 layer close to the Na side is constructed by solution casting.The ionic conductivity is enhanced by using suc-cinonitrile(SN)in polyethylene oxide(PEO)polymer electrolyte.The anti-oxidation layer of Na3Zr2Si2PO12 with Na2SiO3(NZSP-NSO)is served as the support of the membrane on the cathode,which could improve the interface compatibility and electrochemical performance of SSIBs.The asymmetric bilayer solid electrolyte simultaneously features a wide electrochemical stability window(4.65 V vs.Na+/Na)and a high conductivity(2.68×10-4 S cm-1).Furthermore,the solid electrolyte demonstrates stable Na plating/stripping over 700 h and remarkably improves cycling stability in Na/Na3V2(P04)3 bat-teries with an ultra-high capacity retention of 99.6%after 100 cycles at 50℃and 0.5 C.This study pro-vides an effective strategy for designing asymmetric high sodium ion conductivity solid-state electrolytes for high-performance SSIBs.
