Abstract: Two‐dimensional (2D) boron nitride (BN), the so‐called “white graphene,” has demonstrated a great potential in various fields, particularly in electronics and energy, by utilizing its wide bandgap (~5.5 eV), superior thermal stability, high thermal conductance, chemical inertness, and outstanding dielectric properties. However, to further optimize the performances from the view of structure–property relationship, the determinative factors such as crystallite sizes, layer thickness, dispersibility, and surface functionalities should be precisely controlled and adjusted. Therefore, in this review, the synthesis and functionalization methods including “top‐down” and “bottom‐up” strategies, and non‐covalent and covalent modifications for 2D BN are systematically classified and discussed at first, thus catering for the requirements of versatile applications. Then, the progresses of 2D BN applied in the fields of microelectronics such as field‐effect transistors and dielectric capacitors, energy domains such as thermal energy management and conversion, and batteries and supercapacitors are summarized to highlight the importance of 2D BN. Notably, these contents not only contain the state‐of‐the‐art 2D BN composites, but also bring the current novel design of 2D BN‐based microelectronic units. Finally, the challenges and perspectives are proposed to better broaden the scope of this material. Therefore, this review will pave an all‐around way for understanding, utilizing, and applying 2D BN in future electronics and energy applications.

Abstract: High‐efficiency lithium–sulfur (Li–S) batteries depend on an advanced electrode structure that can attain high sulfur utilization at lean‐electrolyte conditions and minimum amount of lithium. Herein, a twinborn holey Nb 4 N 5 –Nb 2 O 5 heterostructure is designed as a dual‐functional host for both redox–kinetics–accelerated sulfur cathode and dendrite‐inhibited lithium anode simultaneously for long‐cycling and lean‐electrolyte Li–S full batteries. Benefiting from the accelerative polysulfides anchoring–diffusion–converting efficiency of Nb 4 N 5 –Nb 2 O 5 , polysulfide‐shutting is significantly alleviated. Meanwhile, the lithiophilic nature of holey Nb 4 N 5 –Nb 2 O 5 is applied as an ion‐redistributor for homogeneous Li‐ion deposition. Taking advantage of these merits, the Li–S full batteries present excellent electrochemical properties, including a minimum capacity decay rate of 0.025% per cycle, and a high areal capacity of 5.0 mAh cm −2 at sulfur loading of 6.9 mg cm −2 , corresponding to negative to positive capacity ratio of 2.4:1 and electrolyte to sulfur ratio of 5.1 µL mg −1 . Therefore, this work paves a new avenue for boosting high‐performances Li–S batteries toward practical applications.

Abstract: Freestanding and flexible graphene olyaniline composite paper was prepared by an in situ anodic electropolymerization of polyaniline film on graphene paper. This graphene-based composite paper electrode, consisting of graphene olyaniline composite sheets as building blocks, shows a favorable tensile strength of 12.6 MPa and a stable large electrochemical capacitance (233 F g(-1) and 135 F cm(-3) for gravimetric and volumetric capacitances), which outperforms many other currently available carbon-based flexible electrodes and is hence particularly promising for flexible supercapacitors.

Abstract: In order to achieve high energy and power densities, we developed a high-voltage asymmetric electrochemical capacitor (EC) based on graphene as negative electrode and a MnO(2) nanowire/graphene composite (MGC) as positive electrode in a neutral aqueous Na(2)SO(4) solution as electrolyte. MGC was prepared by solution-phase assembly of graphene sheets and α-MnO(2) nanowires. Such aqueous electrolyte-based asymmetric ECs can be cycled reversibly in the high-voltage region of 0-2.0 V and exhibit a superior energy density of 30.4 Wh kg(-1), which is much higher than those of symmetric ECs based on graphene//graphene (2.8 Wh kg(-1)) and MGC//MGC (5.2 Wh kg(-1)). Moreover, they present a high power density (5000 W kg(-1) at 7.0 Wh kg(-1)) and acceptable cycling performance of ∼79% retention after 1000 cycles. These findings open up the possibility of graphene-based composites for applications in safe aqueous electrolyte-based high-voltage asymmetric ECs with high energy and power densities.
