Abstract:

Lithium-ion batteries are commercialized due to their high working voltage and energy density.However,the limited lithium resources have hampered their widespread application.Sodium-ion batteries(SIBs) have similar electrochemical behavior and rich sodium salt resources,which have attracted wide attention.The current SIBs use organic electrolytes,which have many safety issues such as leakage and combustion,and the use of solid-state electrolytes can effectively solve the above problems.However,the ionic conductivity of this electrolyte needs to be further improved,and the problems of the consistency of the synthesized material and the large interface impedance between the electrode and electrolyte limit its practical application.To settle the problem of ionic conductivity,the effects of substituted different multi-valence metal ions were summarized and analyzed.In view of the interface problems,the existing interface modification methods of Na1+x Zr2Si x P3-x O12 electrolytes from the cathode and anode sides were reviewed and analyzed.Finally,the development direction of Na1+x Zr2Si x P3-x O12 solid electrolytes was forecasted,which was expected to promote the development of solid SIBs.

Key words: sodium ion batteries, solid-state electrolyte, Na1+x Zr2Si x P3-x O12, ionic conductivity, interface modification
