and electric vehicle broadly, [1] while the lower lithium resource reserve in the earth limits the application for the large scale energy storage in the future. Owing to the earth abundant element reserve of Na in the earth's crust and excellent electrochemical performance of sodium-ion battery, which is an alternative choice to meet the large-scale energy storage system (ESS) for the construction of smart grid and energy internet.Solid sodium-ion battery enjoys high security, high energy density, and shape variability, which is very promising for the application in large-scale ESS. [2,3] Solid electrolytes are key component to provide the transfer of charges by ion movement between two electrodes. However, the low ionic conductivity and poor interface between solid electrolyte and electrode limit the industrial application of solid sodium-ion battery. It is very important for the comprehensive understanding of solid electrolyte/electrode interface mechanism and science and technology problem, as well as the development tendency of solid sodium-ion battery.The overall sodium-ion battery technologies have been reviewed broadly. However, solid electrolyte and interface is rarely concerned yet. Review on sodium-ion battery solid electrolyte and interface is meaningful to design solid sodium-ion battery and improve the safety. The research focus on Na-ion batteries has drastically increased in recent years after 2010, our review mainly provides detailed and comprehensive research progress for sodium-ion battery solid polymer electrolyte and inorganic solid-state electrolyte systems (Figure 1).

“…Over the past decade, storage of energy has happened to an arising global worry due to a growth of smart grid’s needs in inexpensive and sustainable energy storage, 1 in conjunction with extreme rises for the cost of fuels and environmental aftermaths of using them. This raised the call for substitute sources for the generation as well as storage of energy.…”

Polymer composite electrolyte based on polysulfone-sodium sulfonate (SPSU(Na)) blended with poly (polyethylene glycol methacrylate) (PPEGMA) using nano-sized hexagonal boron nitride (nano-hBN) as filler was fabricated using a solution casting technique for use in Na-ion batteries. Polysulfone was sulfonated by a post sulfonation method followed by ion exchange with sodium hydroxide. Fourier transform infrared spectroscopy was used to study SPSU(Na)/PEGMA blend and incorporation of hBN nanoparticle into the SPSU(Na)/PPEGMA blend. Thermal properties of the composites were studied with thermogravimetric analysis (TGA) and differential scanning calorimetry tests. X-ray diffraction was used to study phase change. The TGA curve showed two weight loss regions, where 30% weight loss occurred between 200°C and 350°C due to degradation of sulfonic acid groups, and the polymer backbone degradation occurs above 500°C. Surface morphology of the membranes was examined using scanning electron microscopy which reveals the homogeneous dispersion of the nano-hBN particles in the polymer matrix. Ionic conductivity was studied with impedance spectroscopy and the total ionic conductivity increases with increasing PPEGMA ratio. SPSU(Na)/PPEGMA(1:4) sample showed maximum ion conductivity of approximately 5.5 × 10−6 S cm−1 (5.5 × 10−4 S m−1) at 100°C because of the high content of PPEGMA.
