Dual regulation mechanism of MoS2/MoO3 heterostructure for polysulfide and volume effect enables stable and durable lithium storage

Facile construction of flower-like MoO2/MoS2 heterostructures encapsulated in nitrogen-doped carbon for high-performance sodium-ion storage

“…25 Despite these advantages, the inherently poor electrical and ionic conductivities, along with huge volume changes during Na + insertion/extraction, usually lead to an unsatisfactory rate and cycling performance. 26,27 To overcome these issues, engineering nanostructured MoS 2 is a feasible strategy, which can contribute abundant active sites for Na + storage and shorten the diffusion pathway of Na + to promote ion diffusion kinetics. 28,29 Besides, integrating nanostructured MoS 2 and highly conductive carbon matrixes has been demonstrated to be an effective method to notably enhance the electrical conductivity and effectively accommodate volume expansion of the electrode materials.…”
