“…According to the formula, V = ( E F1 − E F2 )⁄ q , where E F1 and E F2 are Femi levels of heterostructure components, we should choose a wider bandgap and a narrower bandgap as heterostructure electrode components to generate a stronger electric field E . [ 153 ] Generally, anode materials with narrow bandgap include Fe 9 S 10 (0 eV), [ 14 ] FeS (0.1 eV), [ 154 ] NiS 2 (0.3 eV), [ 155 ] and with wide bandgap include ZnS (3.6 eV), [ 156 ] SnO 2 (3.5 eV), [ 157 ] NiO (3.1 eV), [ 158 ] SnS 2 (2.04 eV).

With the ever‐increasing adaption of large‐scale energy storage systems and electric devices, the energy storage capability of batteries and supercapacitors has faced increased demand and challenges. The electrodes of these devices have experienced radical change with the introduction of nano‐scale materials. As new generation materials, heterostructure materials have attracted increasing attention due to their unique interfaces, robust architectures, and synergistic effects, and thus, the ability to enhance the energy/power outputs as well as the lifespan of batteries. In this review, the recent progress in heterostructure from energy storage fields is summarized. Specifically, the fundamental natures of heterostructures, including charge redistribution, built‐in electric field, and associated energy storage mechanisms, are summarized and discussed in detail. Furthermore, various synthesis routes for heterostructures in energy storage fields are roundly reviewed, and their advantages and drawbacks are analyzed. The superiorities and current achievements of heterostructure materials in lithium‐ion batteries (LIBs), sodium‐ion batteries (SIBs), lithium‐sulfur batteries (Li‐S batteries), supercapacitors, and other energy storage devices are discussed. Finally, the authors conclude with the current challenges and perspectives of the heterostructure materials for the fields of energy storage.

“…Additionally, it can recover to 1156.1 mA h g –1 when the rate returns to 0.1 A g –1 , indicating an extremely highly reversible electrochemical reaction and ultrafast Li + -ion diffusion kinetics. To the best of our knowledge, Fe 2 O 3 /MoO 3 @NG accomplishes the greatest rate performance compared with other Fe 2 O 3 -based anodes ,,,− (Figure d and Table S1).

Transition metal oxides (TMOs) hold great potential for lithium-ion batteries (LIBs) on account of the high theoretical capacity. Unfortunately, the unfavorable volume expansion and low intrinsic electronic conductivity of TMOs lead to irreversible structural degradation, disordered particle agglomeration, and sluggish electrochemical reaction kinetics, which result in perishing rate capability and long-term stability. This work reports an Fe 2 O 3 /MoO 3 @NG heterostructure composite for LIBs through the uniform growth of Fe 2 O 3 /MoO 3 heterostructure quantum dots (HQDs) on the N-doped rGO (NG). Due to the synergistic effects of the "couple tree"-type heterostructures constructed by Fe 2 O 3 and MoO 3 with NG, Fe 2 O 3 /MoO 3 @NG delivers a prominent rate performance (322 mA h g −1 at 20 A g −1 , 5.0 times higher than that of Fe 2 O 3 @NG) and long-term cycle stability (433.5 mA h g −1 after 1700 cycles at 10 A g −1 ). Theoretical calculations elucidate that the strong covalent Fe−O−Mo, Mo−N, and Fe−N bonds weaken the diffusion energy barrier and promote the Li + -ion reaction to Fe 2 O 3 /MoO 3 @NG, thereby facilitating the structural stability, pseudocapacitance contribution, and electrochemical reaction kinetics. This work may provide a feasible strategy to promote the practical application of TMO-based LIBs.

With a theoretical capacity of 847 mAh g À 1 , Sn has emerged as promising anode material for sodium-ion batteries (SIBs). However, enormous volume expansion and agglomeration of nano Sn lead to low Coulombic efficiency and poor cycling stability. Herein, an intermetallic FeSn 2 layer is designed via thermal reduction of polymer-Fe 2 O 3 coated hollow SnO 2 spheres to construct a yolk-shell structured Sn/FeSn 2 @C. The FeSn 2 layer can relieve internal stress, avoid the agglomeration of Sn to accelerate the Na + transport, and enable fast electronic conduction, which endows quick electrochemical dynamics and long-term stability. As a result, the Sn/FeSn 2 @C anode exhibits high initial Coulombic efficiency (ICE = 93.8 %) and a high reversible capacity of 409 mAh g À 1 at 1 A g À 1 after 1500 cycles, corresponding to an 80 % capacity retention. In addition, NVP//Sn/FeSn 2 @C sodium-ion full cell shows outstanding cycle stability (capacity retaining rate of 89.7 % after 200 cycles at 1 C).
