| Description | Molybdenum disulfide $(MoS_{2}$) is the most well-known transition metal chalcogenide for lithium storage applications because of its simple preparation process, superior optical, physical, and electrical properties, and high stability. However, recent research has shown that bare $MoS_{2}$ nanosheet (NS) can be reformed to the bulk structure, and sulfur atoms can be dissolved in electrolytes or form polymeric structures, thereby preventing lithium insertion/desertion and reducing cycling performance. To enhance the electrochemical performance of the $MoS_{2}$ NSs, $B_{2}O_{3}$ nanoparticles were decorated on the surface of $MoS_{2}$ NSs via a sintering technique. The structure of $B_{2}O_{3}$ decorated $MoS_{2}$ changed slightly with the formation of a lattice spacing of ~7.37 Å. The characterization of materials confirmed the formation of $B_{2}O_{3}$ crystals at 30% weight percentage of $H_{3}BO_{3}$ starting materials. In particular, the $MoS_{2}$_B3 sample showed a stable capacity of ~500 $mAh·g^{−1}$ after the first cycle. The cycling test delivered a high reversible specific capacity of ~82% of the second cycle after 100 cycles. Furthermore, the rate performance also showed a remarkable recovery capacity of ~98%. These results suggest that the use of $B_{2}O_{3}$ decorations could be a viable method for improving the stability of anode materials in lithium storage applications. |
