Pillaring technologies have been considered as an effective way to improve lithium storage performance of Ti3C2Tx MXene.Nevertheless,the pillared hybrids suffer from sluggish Li+ diffusion kinetics and electronic transportation due to the compact multHayered MXene structure,thus exhibiting inferior rate performance.Herein,the few-layered Ti3C2 MXene (f-Ti3C2 MXene)which is free from restacking can be prepared quickly based on the NH4+ ions method.Besides,Fe nanocomplex pillared few-layered Ti3C2Tx (FPTC) heterostructures are fabricated via the intercalation of Fe ions into the interlayer of f-Ti3C2 MXene.The f-Ti3C2 MXene which is immune to restacking can provide a highly conductive substrate for the rapid transport of Li+ ions and electrons and possess adequate electrolyte accessible area.Moreover,f-Ti3C2 MXene can efficiently relieve the aggregation,prevent the pulverization and buffer the large volume change of Fe nanocomplex during lithiation/delithiation process,leading to enhanced charge transfer kinetics and excellent structural stability of FPTC composites.Consequently,the FPTC hybrids exhibit a high capacity of 535 mAh·g-1 after 150 cycles at 0.5 A.g-1 and an enhanced rate performance with 310 mAh·g-1 after 850 cycles at 5 A·g-1.This strategy is facile,universal and can be extended to fabricate various few-layered MXene-derived hybrids with s uperior rate capability.
