Tuning Interface Bridging Between MoSe2 and Three-Dimensional Carbon Framework by Incorporation of MoC Intermediate to Boost Lithium Storage Capability

“…3a). [43][44][45][46][47]. However, the peak at 1.175 V corresponding to MoC remains constant (the same as this peak at CV curves of MoC/C in Fig.…”

“…The obtained high specific capacity and good rate capability of the MoSe 2 /MoC/N-C electrode also show superiority compared to many other carbon-modified MoSe 2 anode materials (Fig. 3e) [41][42][43][44][45][46][47], which demonstrates the advantage of fast interfacial charge transfer through MoSe 2 / MoC/N-C connection again. What makes the MoSe 2 /MoC/N-C electrode more attractive is its ultralong cycle life with the capacity retention of 90% and a high capacity of 535 mAh g −1 after 5000 cycles at 2 A g −1 (Fig.…”

Facile Synthesis of Ultra‐Small Few‐Layer Nanostructured MoSe2 Embedded on N, P Co‐Doped Bio‐Carbon for High‐Performance Half/Full Sodium‐Ion and Potassium‐Ion Batteries

“…[30][31][32][33][34][35][36][37][38][39][40] Particularly,a sat ypical TMD,m olybdenum diselenide( MoSe 2 )h as al ayered sandwich structure (Se-Mo-Se) with an interlayer distance of 0.65 nm, whichi sn otably larger than that of graphite (0.335nm), and possesses ar elatively high theoretical capacity of 422 mAh g À1 , making MoSe 2 stand out in the vast range of anode materials. [41][42][43][44][45] However,t he weak van der Waals interactionb etween adjacent Se-Mo-Se layers,high surfaceenergy of 2D layers, and inherently low electronic conductivity of bulk MoSe 2 give rise to aggregation of MoSe 2 layers easily and immense volume expansion/contraction, which makes it difficult to function as SIB/PIB electrode materials with satisfactory performance. [46][47][48][49] To ameliorate these drawbacks, variouss trategies have been attempted, includingc onstruction of MoSe 2 with carbon composites, fabricating novel MoSe 2 nanostructures, and rational design of few-layer MoSe 2 .…”

Advanced MoSe2/Carbon Electrodes in Li/Na‐Ions Batteries

“…Obviously, the as‐obtained advantages (multipores, rich pathways, strong building stability) were beneficial for the transportation of charge carriers, thus leading to the enhancement of rate capacity. With the argument of current density (1.0, 2.0, and 5.0 A g −1 ), it displayed a capacity of 371, 326, and 208 mAh g −1 , respectively . It is known that more pores would be created by the utilization of hard template compared to that of soft‐template.…”
