Ultrahigh energy storage and ultrafast ion diffusion in borophene-based anodes for rechargeable metal ion batteries

Abstract

Since the turn of the new century, the increasing demand for high-performance energy storage systems has generated considerable interest in rechargeable ion batteries.

Orbitally driven giant thermal conductance associated with abnormal strain dependence in hydrogenated graphene-like borophene

“…33,34 Following the realization of the buckled phase and the planar phase of borophene, extensive theoretical studies were conducted to explore the various applications of borophene such as hydrogen storage, rechargeable metal-ion batteries, superconductors, heat channel and mechanically robust components. [35][36][37][38][39][40][41][42][43][44][45][46][47] In particular, the strain effects on the electronic, optical, and transport properties of borophene are explored. 39,44,[48][49][50] The fascinating behaviors revealed here in 2D hydrogen boride sheet not only widen our knowledge in thermal transport in 2D materials, but also provide a new route to manipulate the thermal conductance since it is much easier for controlling electrons than controlling phonons.…”

Xenes as an Emerging 2D Monoelemental Family: Fundamental Electrochemistry and Energy Applications

“…Fortunately, theoretical investigations pointed out that non-ideal structures such asribbon structures, point defects, and surface functional groups, can not significantly influence the capacity stability of borophene for LIBs. [175] In the pnictogen family, multi-layered phosphorene was the first to be investigated for its electrochemistry in both theory and experiment, which proved its excellent performance in this field. [176] Environmental oxygen, water, and visible light have been confirmed by Martel and co-workers to be three key factors on the degradation of phosphoene monolayer, as shown in Figure 4a.…”

Borophene: A Metal‐free and Metallic Electrocatalyst for Efficient Converting CO2 into CH4

“…Very recently, micron‐sized 2D boron sheet (up to 100 μm 2 ) has been obtained in experiment, indicating the enormous potential of the fabrication of 2D‐boron‐based devices in many fields . For example, borophene and borophene based anodes are both expected to be used as excellent lithium‐ion batteries or other rechargeable metal ion batteries . Moreover, some electrocatalysts comprising borophene subunits possess high activity in hydrogen evolution (HER), nitrogen reduction reaction (NRR) and carbon dioxide reduction .…”

“…[36] For example, borophene and borophene based anodes are both expected to be used as excellent lithium-ion batteries or other rechargeable metal ion batteries. [37][38][39][40][41][42] Moreover, some electrocatalysts comprising borophene subunits possess high activity in hydrogen evolution (HER), nitrogen reduction reaction (NRR) and carbon dioxide reduction. [43][44][45][46] Some hydrogenated 2D boron sheets are all proved to be dynamically stable, and importantly, they exhibit Dirac cones with massless Dirac fermions.…”
