MoS2/graphene nanosheet composites prepared by xylitol-assisted ball milling as high-performance anode materials for lithium-ion batteries

Monodisperse MoS2/Graphite Composite Anode Materials for Advanced Lithium Ion Batteries

“…When MoS 2 :graphite = 80%:20%, the cycle performance is the worst, and the capacity retention rate is only 36.83%. Along with the decreasing percentage of C elements in MoS 2 /graphite materials, the electrical conductivity and structural stability of the composites will continue to deteriorate, which is the reason for the decreasing trend of the cyclic capacity retention of the composites [ 31 ].…”

Response surface methodology: a powerful tool for optimizing the synthesis of metal sulfide nanoparticles for dye degradation

“…The preparation of small nanosized particles involves the breakdown of bulk precursor material using various physical methods, such as sputtering, grinding, milling, thermal or laser ablation. [51][52][53][54][55] These processes result in the formation of nanoparticles with reduced dimensions compared to the original bulk material. 56 Top-down methods are categorized into two type of methods: Scotch tape method.…”

Few-layer MoS2 nanosheets vertically supported on Ti3C2-MXene sheets promoting lithium storage performance

“…3 2H-MoS 2 undergoes an intercalation/deintercalation mechanism that is completely reversible in its lithium storage process between 3 V and 1.1 V, and a conversion reaction occurs below 1.1 V. To compensate for the low electronic conductivity and the volume expansion (about 103%) of 2H-MoS 2 4 as a conversion reaction material, researchers have tried to improve its performance by adding conductive frameworks such as graphene and carbon nanotubes. [5][6][7][8][9][10] G composites with significantly improved cycling performance compared to MoS 2 that showed a bulk particle morphology without graphene addition. 11 An MXene is a typical two-dimensional material that is separated from the MAX phase by a top-down method similar to the exfoliation of graphene from graphite.…”
