Synthesis of Nanostructured Bismuth Sulfide with Controllable Morphology for Advanced Lithium/Sodium-Ion Storage

Abstract

Rational design of electrode materials with an excellent structure and morphology is crucial for improving electrochemical properties. Herein, various unique nanostructured Bi 2 S 3 materials with controllable morphology were obtained through a simple and efficient oil bath reaction strategy. Bi 2 S 3 with different morphologies can be obtained by regulating the polarity of solvent, and the lattice spacing can also be adjusted. The Bi 2 S 3 nanomaterials obtained with ethanol as solvent (BS-3) show a three-dimensional nanoflower-like structure assembled with porous layers. The unique structure facilitates the transport of ions and accommodates the volume variation of Bi 2 S 3 during energy storage. Consequently, BS-3 nanoflowers exhibited superior cycling stability and excellent high-rate capability for lithium storage (maintained a high capacity of 923.8 mA h g −1 after 950 cycles at 1.0 A g −1 ) and excellent sodium storage. We provide guidance for precise synthesis and energy storage application of Bi 2 S 3 nanomaterials.

Mini‐Review: Progress on the Controllable Synthesis of Micro/Nanoscale Bi2S3 Functional Materials

“…The reaction kinetics can be affected by the numbers of initial nucleations through altering the reaction parameters, so as to cause the oriented growth of crystal structure sorts and further influence the properties of materials, such as the size, shape, structure, and purity of these materials. [29] Up to now, typical structures of Bi 2 S 3 (such as nanowires, [30,31] nanorods, [32][33][34][35] nanotubes, [36][37][38] nanobelts, [39] nanowhiskers, [40] nanoflowers, [41][42][43] snowflakelike, [44] and urchin-like nanospheres [45] ) have been successfully gained via the hydrothermal, [46][47][48][49][50][51][52][53][54][55][56][57][58][59] solvothermal, [60][61][62][63][64][65][66][67][68][69][70][71][72] ionic liquid-assisted, [73][74]…”
