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

“…In addition, it can be noted that the layer numbers of ultra-fine MoSe 2 nanosheets in MoSe 2 /NP-C-2 are approximately 1-3 layers (Figure 1d), which is conducive to the shortening of ion/ electron transport, as well as the promotion of reactionk inetics and electrolyte penetration. [52,66,67] In addition, the lattice fringe with an interplanar spacing of 0.65 nm can be clearly observedf rom Figure S2 (in the Supporting Information), which is in good agreement with the (0 02)p lane of MoSe 2 . The elemental mapping results ( Figure 1e and Figure S3 in the Supporting Information) further demonstrate the co-existence of homogeneously dispersed Mo, Se, C, N, and Pe lements on the MoSe 2 /NP-C-2 composite.…”

Nitrogen‐Doped MoS2 Foam for Fast Sodium Ion Storage

“…In the deep cathodic process, a broadened reduction peak around at 0.5 V is assigned to the electrochemical decomposition of Na x MoS 2 to form metallic Mo nanoparticles embedded in an amorphous Na 2 S matrix which can be described by Equation . Subsequently, a peak approximately at 0.1 V is due to the accumulation of sodium ions in the surface of Na 2 S and Mo . In the first anodic scan, a broad oxidation peak approximately at 1.78 V can be corresponded to the oxidation reaction from Mo nanograins to MoS 2 .…”

“…The specific surface area of NMF was measured to be 64.21 m 2 g −1 . The high surface areas and rich porous structure greatly promote the diffusion of electrolyte and shorten the ion transmission distance, finally effectively improving the electrochemical performance of NMF …”

An integrated electrode based on nanoflakes of MoS2 on carbon cloth for enhanced lithium storage

“…In recent years, the rapid advances in the eld of exible and portable devices (such as exible smartphones, rollup displays and wearable electronics) have triggered the requirements for exible energy storage systems with excellent mechanical and electrical properties. [1][2][3][4][5] For instance, with the development of implantable/wearable healthcare devices, new self-sustainable energy storage devices have been developed. 6 Amongst the available commercial power sources, exible lithium-ion batteries (LIBs) have attracted a special attention.…”

“…15 To address these issues, one of the strategies is to construct MoS 2 in combination with exible and conductive substrates. 1,10,14,[16][17][18][19][20] However, the complex preparation process of these integrated electrodes is still a major obstacle. It is therefore necessary to further optimize the synthesis process of MoS 2 -based exible electrodes by using a facile and low-cost technique that is suitable for exible electronic devices with enhanced electrochemical performances.…”
