Summary In this paper, nanosized Ni3Sn4 nanoparticles were synthesized by chemical reduction technique. A facile strategy is also developed to synthesize the yolk‐shell Ni3Sn4 nanoparticles decorated between the layers of multilayer graphene to obtain high‐capacity, long service life with comparable cost Li‐ion batteries. Ni3Sn4 nanoparticles in the form of yolk‐shell morphology were synthesized between 30 and 130 nm in size and homogeneously anchored on graphene layers as spacers preventing the layers merging after vacuum filtration. The characterization of the as‐synthesized composite electrodes was performed by scanning electron microscopy and X‐ray diffraction methods. As an anode electrode, yolk‐shell Ni3Sn4/graphene composite electrodes revealed a stable capacity of 324.5 mAh g−1 after 250 cycles, indicating that the composites might have a promising future application in Li‐ion batteries. The results have shown that unique yolk‐shell Ni3Sn4/graphene hybrid composite structure shows extraordinary electrochemical performance with superior reversible capacity and improved cyclic performance, indicating that the stacking of the active electrode nanoparticles between the graphene layers is a good method for maximum specific capacity outputs.

Seeking a simple direct construction strategy for transition‐metal‐phosphide‐based composites as anodes for sodium‐ion batteries is attracting great attention for the development of high‐performance sodium‐ion batteries. In this work, we design iron phosphide nanosheets grown on a biomass carbon membrane by a facile electrodeposition method, followed by an annealing process. The biomass carbon membranes as three dimensional frameworks, possessing initial biological structures from Magnolia leaves, do not only improve the conductivity of the electrodes but also relieve iron phosphide aggregation during the charging‐discharging processes. The iron phosphide nanosheets could increase the accessible surface area for electrochemical reactions, further promoting the storage of sodium ions. Due to the unique structure of the iron phosphide nanosheets/biomass carbon membrane, the electrodes exhibit 500.9 mAh g−1 at a current density of 50 mA g−1 after 100 cycles. Even at a high current density of 500 mA g−1, the electrodes still retain 197 mAh g−1 after a long‐time test (500 cycles). These novel features make the composite a great potential anode material for binder‐free sodium‐ion batteries.

“…The release of gas during the thermal pyrolysis is mainly responsible for the formation of porous structure. Larger BET surface area and abundant porosity can provide more Li‐ion diffusion channels in both carbon sheets and host materials, which favors the charge and electron transfer during the charge and discharge, as well as alleviate the strain stress . Figure c displays Raman spectra of both MoS 0.5 Se 1.5 /C and MoSe 2 /C.…”

COMMUNICATION (1 of 7)Lithium ion (Li-ion) batteries have been powering portable electronics since their emergence in the early 1990s; [1] however, their limited energy and power density impedes further extension of application to automobiles. To achieve the increase in energy and power density of Li-ion batteries, the development of effective electrode materials is essential. [2][3][4][5] Currently, the commercial anode materials of Li-ion batteries are dependent heavily on graphite carbon, [6][7][8][9] but the low theoretical capacity (372 mAh g −1 ) and relatively poor rate capability cannot meet the increasing demands in Li-ion batteries. [10][11][12][13] Therefore, developing the alternative anode materials to meet the demands of future battery units is an urgent task.Emerging as a class of potential alternative, transition metal dichalcogenides (TMDs), MX 2 (M = Mo, W, Co, Sn; X = S, Se), [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] have been in the spotlight recently as anode materials because of their open 2D layered structure and high theoretical specific capacity, as well as remarkable electronic properties. Atoms within 2D layers are bound via strong covalent bonds (XMX), while the bonding between layers is through weak van der Waals force, forming a sandwich-like structure [31,32] that favors the intercalation/ deintercalation of Li ions. Relative to widely studied MoS 2 (interlayer space: 0.615 nm), MoSe 2 possesses larger interlayer space of about ≈0.646 nm and smaller band gap of ≈1.5 eV. [33][34][35] Thus, the excellent Li-ion storage performance of MoSe 2 can be expected. As a semiconductor, the inherently inferior electrochemical conductivity of MoSe 2 still significantly impends the practical availability in the case of large current charge/discharge. On the other hand, the intrinsic layer structure of MoSe 2 generally inclines to restack in the cyclic course, resulting in rapid fading of reversible capacity and unsatisfying cyclic stability. Therefore, the incorporation of more conductive compositions and building of robust structure is desirable to enhance electrochemical performance of MoSe 2 -based materials in Li-ion batteries, yet still challenging.Herein, we design an effective and general KCl-assisted strategy to synthesize S-doped MoSe 2 (MoS 0.5 Se 1.5 ) that is homogeneously embedded in 2D porous graphitic carbon sheets (denoted as MoS 0.5 Se 1.5 /C sheets) as a promising anode of Li-ion batteries. To the best of our knowledge, such KCl-assisted
