Lithium-based electrolytes are, at least from a thermodynamic standpoint, the most suitable ion-transport materials for energy storage systems. However, lithium-based ionic conductors suffer from safety concerns, and the limited availability of lithium in the Earth’s crust is at the root of the need to consider alternative metal ions. Notably, sodium stands out as the sixth most-prevalent element; therefore, when considering mineral reserves, it as a very attractive candidate as an alternative to the status quo. Even if the specific energy and energy density of sodium are indeed inferior with respect to those of lithium, there is substantial economic appeal in promoting the use of the former metal in stationary energy storage applications. For these reasons, the promise of sodium is likely to extend to other commercial applications, including portable electronics, as well as hybrid and electric vehicles. Widely used organic liquid electrolytes, regardless of their chosen metal cation, are disadvantageous due to leakage, evaporation, and high flammability. Polymer electrolytes are acknowledged as the most effective candidates to overcome these obstacles and facilitate the advancement of next-generation energy storage applications. In this contribution, an in-depth and comprehensive review of sodium polymer electrolytes for primary and secondary batteries is proposed. The overarching goal was to gain insight into successful synthetic strategies and their implications for conduction parameters and conductivity mechanisms. The focus lies on solid, gel, and composite polymer electrolytes. Our hope is that the proposed discussion will be helpful to all operators in the field, whether in tackling fundamental research problems or resolving issues of practical significance.

“…[8] An SPE of (1-x) PEO:xNaCl (0 < x < 50 in wt%) prepared by hot-press/dry technique showed the optimum ion conductivity of 4.5 × 10 −6 S cm −1 at room temperature when the composition was 70PEO:30NaCl. [9] A hot-pressed SPE of [75PEO:25NaPO 3 ] was shown that Na + contributed all ionic transference for the charge transference in the SPE. [10] A PEO 16 -NaPF 6 solid electrolyte showed ionic conductivity around 6.3 × 10 −4 S cm −1 at 80 °C, Na + transference number ≈0.58 and thermal stability up to 200 °C, as well as an excellent interfacial stability with Na anode.…”

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).
