“…Therefore, it was proposed that the Lewis acid‐base reaction enhances the ionic conductivity. Later in 2021, the effect of TiO 2 addition into the PEO−NaI matrices was also investigated [104] and it was noted that three factors account for the enhancement of ionic conductivity due to the added TiO 2 , which are increased amorphous degree, Lewis acid‐base reaction and newly built sodium ion conduction pathways. The Lewis acid‐base reaction is due to the interaction between the polar surface groups of ceramic filler and polymer matrix, which create new pathways and migration sites for sodium ion conduction [105,106] .…”

Sodium‐ion batteries (SIBs) are expected to become alternatives to lithium‐ion batteries (LIBs) as next‐generation rechargeable batteries, owing to abundant sodium sources and low cost. However, SIBs still use liquid organic electrolytes (LOEs), which are highly flammable and have the tendency to leak. Although inorganic solid electrolytes (ISEs) and solid polymer electrolytes (SPEs) have been investigated for many years, given their higher safety level, neither of them is likely to be commercialized because of the rigidity of ISEs and the low room‐temperature ionic conductivity of SPEs. During the last decade, composite polymer electrolytes (CPEs), composed of ISEs and SPEs, exhibiting both relatively high ionic conductivity and flexibility, have gained much attention and are considered as promising electrolytes. However, the ionic conductivities of CPEs are still unsatisfactory for practical application. Hence, this Review focuses on the principle of sodium ion conductors and particularly on recent investigations and development of CPEs.
