“…In addition, another unique van der Waals heterostructured, BP nanosheet@TiO2@graphene hydrogel, was explored by Sun's group. 69 TiO2 nanoparticles were firstly in situ grown on graphene networks (3D TiO2@G), and then coated by the BP nanosheets, forming the final BPNs@TiO2@G heterostructure, which provided a widened potential window (~3.0 V), increased initial capacity (1336.1 mAh g -1 at 0.2 A g -1 ), improved rate performance (271.1 mAh g -1 at 5.0 A g -1 ) and enhanced cycling stability (502 mAh g -1 after 180 cycles). The satisfactory electrochemical performance could be ascribed to the unique heterostructures combining BP nanosheet, TiO2, and graphene with improved electrical conductivity, enriched chemically-active defects and rapid interlayer charge/mass transfer paths (Figure 8f).…”

“…For example, a BPNS/TiO 2 /graphene hybrid hydrogel was prepared by dip‐coating liquid exfoliated BPNSs onto a preprepared 3D TiO 2 –graphene composite hydrogel. [ 110 ] Compared to other heterostructures, BPNS‐based heterostructures need to be constructed in a glovebox to avoid oxidizing the BPNSs during processing. [ 111 ]…”

Assembling different kinds of 2D nanosheets into heterostructures presents a promising way of designing novel artificial materials with new and improved functionalities by combining the unique properties of each component. In the past few years, black phosphorus nanosheets (BPNSs) have been recognized as a highly feasible 2D material with outstanding electronic properties, a tunable bandgap, and strong in‐plane anisotropy, highlighting their suitability as a material for constructing heterostructures. In this study, recent progress in the construction of BPNS‐based heterostructures ranging from 2D hybrid structures to 3D networks is discussed, emphasizing the different types of interactions (covalent or noncovalent) between individual layers. The preparation methods, optical and electronic properties, and various applications of these heterostructures—including electronic and optoelectronic devices, energy storage devices, photocatalysis and electrocatalysis, and biological applications—are discussed. Finally, critical challenges and prospective research aspects in BPNS‐based heterostructures are also highlighted.

“…[ 247 ] In brief, there are two primary and common types of Li + storage mechanisms, namely alloying‐type (M x O y + 2 y Li + + 2 y e − ⇄ x M + y Li 2 O; M + z Li + + z e − ⇄ Li z M, e.g., SnO 2 ) and conversion‐type (M x O y + 2 y Li + + 2 y e − ⇄ x M + y Li 2 O, e.g., Co 3 O 4 , Fe 2 O 3 , Mn 3 O 4 ). [ 248–253 ] Among TMOs, spinel TMOs are believed to be promising anode materials based on the two‐step reaction during the equilibrium lithiation process, in which intercalation and conversion occur sequentially, from the viewpoint of chemical thermodynamics. However, the HRTEM images obtained during the in situ and ex situ Li intercalation, which explicitly visualized magnetite (Fe 3 O 4 ) spinel, confirmed that the initial Li intercalation process, in which the rocksalt LiFe 3 O 4 phase was formed (Figure 11e–h) significantly overlapped with the subsequent conversion reaction, and that indicated that the reaction kinetics played a crucial role during lithiation.…”

dimensions of materials are decreased to the nanoscale, the high surface aspect ratio generates additional engineerable space, which enables the polymorphism of nanomaterials. Recently, nano polymorphism (NPM) has been emerging as a topic of interest in the energy storage field, and research is expected to identify and rationally exploit the "processingstructure-properties" relationships of functional materials of interest in the context of the emerging rechargeable battery applications, particularly for cathode and anode materials. To date, the research on the NPM of rechargeable battery electrodes has achieved significant progress. [1-3] Many electrode materials with various polymorphs, such as traditional layered metal oxides and some emerging types of graphene-like nanosized materials, have been intensively investigated for improving the electrochemical performance of batteries. Moreover, the in-depth underlying storage mechanisms of different polymorphs have been fully or partly revealed using advanced in situ characterization techniques. Based on the previously reported theoretical and experimental results, some potential structural Nano polymorphism (NPM), as an emerging research area in the field of energy storage, and rechargeable batteries, have attracted much attention recently. In this review, the recent progress on the composition and formation of polymorphs, and the evolution processes of different redox electrodes in rechargeable metal-ion, metal-air, and metal-sulfur batteries are highlighted. First, NPM and its significance for rechargeable batteries are discussed. Subsequently, the current NPM modulation strategies of different types of representative electrodes for their corresponding rechargeable battery applications are summarized. The goal is to demonstrate how NPM could tune the intrinsic material properties, and hence, improve their electrochemical activities for each battery type. It is expected that the analysis of polymorphism and electrochemical properties of materials could help identify some "processing-structure-properties" relationships for material design and performance enhancement. Lastly, the current research challenges and potential research directions are discussed to offer guidance and perspectives for future research on NPM engineering.
