      Sheets as Efficient Electrocatalysts for Lithium-Sulfur Batteries.

AB  - Two-dimensional (2D) borophene has attracted tremendous interest due to its 
      fascinating properties, which have potential applications in catalysts, energy 
      storage devices, and high-speed transistors. In the past few years, borophene was 
      theoretically predicted as an ideal electrode material for lithium-sulfur (Li-S) 
      batteries because of its low-density, metallic conductivity, high Li-ion surface 
      mobility, and strong interface bonding energy to polysulfide. But until now, 
      borophene-based Li-S batteries have not yet been achieved in experiments due to 
      the absence of a large-scale synthetic method of freestanding borophene 
      nanostructures with a high enough structural stability, conductivity, and 
      uniformity. Herein, we developed a low-temperature liquid exfoliation (LTLE) 
      method to synthesize freestanding few-layer beta(12)-borophene single-crystalline 
      sheets with a P6 m2 symmetry in tens of milligrams. The as-synthesized 2D sheets 
      were used as the polysulfide immobilizers and electrocatalysts of Li-S batteries. 
      The resulting borophene-based Li-S battery delivered an extralarge areal capacity 
      of 5.2 mAh cm(-2) at a high sulfur loading of 7.8 mg cm(-2), an excellent rate 
      performance of 8 C (@721 mAh g(-1)), and an ultralow capacity fading rate of 
      0.039% in 1000 cycles, outperforming commercial Li-ion batteries and many other 
      2D material-based Li-S batteries. Based on the density functional theory model, 
      the excellent electrochemical performances of the borophene-based Li-S batteries 
      should originate from the enormous enhancement of beta(12)-borophene sheets for both 
      the surface migration of the Li-ions and the adsorption energy of Li(2)S(n) 
      clusters. Our results thus demonstrate a great potential for scalable production 
      of freestanding beta(12)-borophene single-crystalline sheets in future 
      high-performance Li-S batteries.
