Emerging of Heterostructure Materials in Energy Storage: A Review

Abstract

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.

Metal–CO2 Electrochemistry: From CO2 Recycling to Energy Storage

“…This concept was proposed by W. Shockley in the field of semiconductor physics, which refers to the structure composed of different semiconductors with similar crystal structure and similar atomic spacing and thermal expansion coefficient. [139] Due to the unmatched Fermi levels, majority carrier types and concentrations difference of building blocks, the electrons and holes will spontaneously migrate across the heterophase boundaries, and tailor the electronic/ionic structure of the heterogeneous catalyst, leading to excellent electrochemical performance. In addition, the built-in electric field induced by charge redistribution around heterointerfaces can accelerate the transfer of charge to the reactants on the surface of the catalyst, thus improving its catalytic performance.…”

The Multicomponent Synergistic Effect of Sandwich Structure Hierarchical Nanofibers for Enhanced Sodium Storage

“…[10,[12][13][14] However, the poor intrinsic conductivity and severe volume change during the cycle process of MoS 2 limit the practical application. Various strategies on the modulation of micro/nanostructure, [15][16][17] construction of heterostructure, [3] and expansion of the interlayer distance [11,16] are adopted to improve sodium storage performance of MoS 2 . Ye et al [12] have prepared phase twinned MoS 2 nanowires with extended interlayers via reasonable structural designs, which show better electrochemical performance for SIBs than single-phase MoS 2 .…”

“…In recent years, the rising production of electric vehicles and portable electronic products has increased the demand for energy storage devices-lithium ion batteries (LIBs). [1][2][3] However, due to the uneven global distribution and limited reserves of the Li element, sodium ion batteries (SIBs) with similar However, during long cycle processes, the pulverization of heterostructures based on TMS and dissolution in ether or ester-based electrolytes will cause severe capacity attenuation. Wrapping carbon materials with a certain thickness on the surface of heterojunctions can effectively alleviate the above problems.…”

“…To the best of our knowledge, there are few reports on TMO/TMN heterojunctions as anode materials for LIBs. [30][31][32][33][34] Substantial experimental and theoretical efforts are still extremely needed to explore precise heterojunctions and understand their actual effects on Li + storage behaviors.…”
