ABSTRACT Several emerging energy storage technologies and systems have been demonstrated that feature low cost, high rate capability, and durability for potential use in large-scale grid and high-power applications. Owing to its outstanding ion conductivity, ultrafast Na-ion insertion kinetics, excellent structural stability, and large theoretical capacity, the sodium superionic conductor (NASICON)-structured insertion material NaTi 2(PO4)3 (NTP) has attracted considerable attention as the opti- mal electrode material for sodium-ion batteries (SIBs) and Na-ion hybrid capacitors (NHCs).
