“…[33] For Li ion full-cell testing, the number of Li ions in the system is limited, the irreversible Li ion loss will lead to the capacity loss permanently. [32] The initial discharge capacities of the pure MoO 2 particles, micrometer MoO 2 /GO, MoO 2 /GO nanohoneycomb, and layered MoO 2 /GO are 914, 1057, 1075, and 904 mAh g −1 , respectively.…”

the theoretical capacity of graphite electrodes is 372 mAh g −1 , resulted in an obstacle for their potential applications. The strategies to develop alternative anode materials with improved capacity have been achieved for several decades. [1][2][3][4][5][6][7][8] Among them, nanoscale metal oxides, including MnO, [9] SnO 2 , [10,11] Co 3 O 4 , [12] NiO, [13] and Fe 3 O 4 , [14,15] used as anode active materials for LIBs have been paid much attention attributed to their promising theoretical capacity. However, in most cases, the capacity decays rapidly as cycled due to high electrical resistivity and mechanism failure. [16] Molybdenum oxide (MoO 2 ) is different from other metal oxides. It possesses metallic conductivity (its electrical resistivity is 8.8 × 10 −5 Ω cm at 300 K in bulk sample), with a theoretical capacity as high as 836 mAh g −1 . [17] However, the capacity of bulk MoO 2 is low due to sluggish lithiation/delithiation kinetics. [17][18][19][20] On the other hand, the nanoporous structure constructed with lots of interconnect nanounits to form numbers of nanoscale pore provides adequate spaces for electrochemical reaction and connected pathways for ion diffusion. [21,22] The nano-MoO 2 porous structures have been synthesized by using mesoporous silica as hard templates, followed removing this hard templates by hydrofluoric acid, [23] or by a sulfur-assisted decomposition process. [24] The prepared MoO 2 porous materials have displayed improved capacity for LIBs. However, the capacity fade after charge/discharge process is attributed to the pure MoO 2 skeleton that will be possibly collapsed. The cycle stability needs to be improved further. It should be desired for the MoO 2 porous structure with flexible supports via retarding the pulverization from pure MoO 2 skeleton.Carbon nanomaterials, especially, graphene with large specific surface area and high toughness, are suitable for both substrates and supports for MoO 2 electrode active materials. However, owing to graphene being liable to stack together, it is difficult to prepare well distributed graphene templated metal oxide architectures. The strategies, including solid-state graphenothermal reduction method, [25] microwave-assisted hydrothermal process, [26] and soft-templated hydrothermal method, [27] have been used to synthesize MoO 2 /C nanocomposites, exhibiting promising performance for LIBs.

“…The sacrificial-template approaches involving fantastic mechanisms such as self-templating, [71,77,83,140] chemical oxidation reaction, [76] thermal decomposition, [33] ion-exchange reaction [78,141,142] and kirkendall effects [143] have demonstrated their feasibility and effectiveness to prepare high-quality hierarchical hollow structures with distinct morphologies and compositions. For instance, Qian and co-workers developed a hollow MoS 2 @C nanotube using a simple hydrothermal sulfuration of Mo 3 O 10 (C 2 H 10 N 2 ) nanowire method along with glucose carbonization, which can be explained by the nanoscale Kirkendall effect.…”

Two‐dimensional (2D) nanomaterials (i.e., graphene and its derivatives, transition metal oxides and transition metal dichalcogenides) are receiving a lot attention in energy storage application because of their unprecedented properties and great diversities. However, their re‐stacking or aggregation during the electrode fabrication process has greatly hindered their further developments and applications in rechargeable lithium batteries. Recently, rationally designed hierarchical structures based on 2D nanomaterials have emerged as promising candidates in rechargeable lithium battery applications. Numerous synthetic strategies have been developed to obtain hierarchical structures and high‐performance energy storage devices based on these hierarchical structure have been realized. This review summarizes the synthesis and characteristics of three styles of hierarchical architecture, namely three‐dimensional (3D) porous network nanostructures, hollow nanostructures and self‐supported nanoarrays, presents the representative applications of hierarchical structured nanomaterials as functional materials for lithium ion batteries, lithium‐sulfur batteries and lithium‐oxygen batteries, meanwhile sheds light particularly on the relationship between structure engineering and improved electrochemical performance; and provides the existing challenges and the perspectives for this fast emerging field.

A facile vacuum filtration method is applied for the first time to construct sandwich-structure anode. Two layers of graphene stacks sandwich a composite of black phosphorus (BP), which not only protect BP from quickly degenerating but also serve as current collector instead of copper foil. The BP composite, reduced graphene oxide coated on BP via chemical bonding, is simply synthesized by solvothermal reaction at 140 °C. The sandwiched film anode used for lithium-ion battery exhibits reversible capacities of 1401 mAh g during the 200th cycle at current density of 100 mA g indicating superior cycle performance. Besides, this facile vacuum filtration method may also be available for other anode material with well dispersion in N-methyl pyrrolidone (NMP).
