Construction of hierarchical MoSe₂@C hollow nanospheres for efficient lithium/sodium ion storage

Abstract

Hierarchical MoSe2@C hollow nanospheres are synthesized via an anion-exchange reaction and exhibit good electrochemical performance.

Three-Dimensional Hierarchical MoSe2/N, F Co-Doped Carbon Heterostructure Assembled by Ultrathin Nanosheets for Advanced Lithium-Ion Batteries

“…19 Hou et al reported the use of MoSe 2 @C hollow nanospheres in LIBs, which can achieve a high reversible capacity of 711 mAh g −1 after 300 cycles. 20 Thus, the above results strongly suggest that the morphology design or combining MoSe 2 with carbonaceous materials can enhance the cycle/rate performance of MoSe 2 . However, both excellent rate performance and ultralong cycle life for MoSe combination of the two methods, one can simultaneously achieve outstanding rate performance and ultralong cycle stability for MoSe 2 anodes.…”

“…Structure design and combining MoSe 2 with carbon materials are two effective methods to enhance lithium storage properties. , For example, Wu et al synthesized few-layered MoSe 2 nanosheets via a jet cavitation process, which obviously resulted in enhanced electrochemical performance, especially the rate capability . Hou et al reported the use of MoSe 2 @C hollow nanospheres in LIBs, which can achieve a high reversible capacity of 711 mAh g –1 after 300 cycles .

Organic–inorganic assembly engineering of core–double-shell VSe1.6/C@N–C⊂MoSe2 nanotubes for boosting Na+/K+ storage performance

“…The sharp weight loss above 300 °C can be divided into two stages, corresponding to the oxidation of VSe 1.6 and MoSe 2 to V 2 O 5 and MoO 3 , which is slightly different from the weight loss of VSe 1.6 /C@N–C and VSe 1.6 /C. 42,43 Based on the weight losses, the carbon contents are calculated to be 39.5%, 47.5%, and 45.7% for VSe 1.6 /C, VSe 1.6 /C@N–C, and VSe 1.6 /C@N–C⊂MoSe 2 , respectively. Through the analysis of the TGA results (provided in the ESI†), the weight contents of VSe 1.6 , MoSe 2 and carbon in the VSe 1.6 /C@N–C⊂MoSe 2 hybrid are estimated to be ∼45.7%, ∼12.9%, and ∼41.4%, respectively.…”

Self-templating synthesis of heteroatom-doped large-scalable carbon anodes for high-performance lithium-ion batteries

“…However, its low theoretical specific capacity (372 mA h g −1 ) cannot meet the rapidly increasing demand for electric vehicles in the vastly emerging market in recent years. 18–23 For large-scale commercial electricity storage, therefore, the performance capability, electrode durability and safety perspective need to be further improved. 24–26 As such, it is urgent to design novel anode materials that possess high theoretical capacities with excellent cycling and rate performance for advanced LIBs.…”
