“…It can be observed in Figure d that this reasonable design provides high surface area, short ion diffusion lengths, and effective electron transport pathways, further resulting in improved cycling and rate performance. A recent work reported that a type of phase‐pure b‐NiMoO 4 yolk–shell spheres can be obtained at pyrolysis temperature of 800 °C via one‐pot spray pyrolysis . In this design, the unique core/void/shell configuration with free space could better function to accommodate the volume change upon cycling.…”

improved LIB performance is in the electrode materials. [ 11 ] Presently, commercial anode materials mainly include graphite, which limits the lithium storage performance in terms of energy and power density due to the low theoretical capacity (LiC 6 , 372 mAh g −1 ) and low Li-ion transport rate. [12][13][14] New anode materials with higher capacities are being looked for including mixed transition metal oxide anodes. Traditional Metal Oxide AnodesNew research is constantly being carried out to reach the high requirements for LIB anodes. Various metal oxide materials such as SnO 2 , [15][16][17][18][19] Co 3 O 4 , [20][21][22][23] NiO, [24][25][26][27] Fe 3 O 4 , [28][29][30] and MnO 2 [31][32][33] are alternative potential anodes for LIBs due to their high theoretical capacities, high power density, and wide usefulness. However, metal oxides inevitably suffer from several major problems: severe volume changes during the alloying-dealloying processes, pulverization and agglomeration of primitive particles, and poor electronic conductivity that hinders the reaction with lithium during electrochemical reactions. Numerous approaches have attempted to address these challenges. One useful method is to develop the metal oxide materials into nanostructures. [ 3 ] The distinct lithium storage mechanisms and the infl uence of unique structures on the lithium storage properties of the metal oxide materials have been reported in detail. [ 5 ] A series of work on the design of various nanostructures of metal oxide materials has been subsequently carried out, for nanomaterials of different dimensions, hollow structures, and hierarchical structures. [ 5 ] Coating or combining the buffering matrix or conductive materials with metal oxide materials is another way to relieve the severe problems. [36][37][38][39][40][41][42] Various carbon materials, especially novel nanocarbon materials like carbon nanotubes and graphene nanosheets, have been widely studied as the buffering and conductive agent for metal oxide anodes. [43][44][45][46] In our previous review, [ 47 ] the signifi cant effects of graphene nanosheets on tin-based anodes were summarized in detail. It has been concluded that graphene not only contributes as a highly conductive network, but also as a fl exible supporting layer, effectively relieving the volume change and particle aggregation. In addition, different metals and metal oxides that are electrochemically active and Mixed transition-metal oxides (MTMOs), including stannates, ferrites, cobaltates, and nickelates, have attracted increased attention in the application of high performance lithium-ion batteries. Compared with traditional metal oxides, MTMOs exhibit enormous potential as electrode materials in lithium-ion batteries originating from higher reversible capacity, better structural stability, and high electronic conductivity. Recent advancements in the rational design of novel MTMO micro/nanostructures for lithium-ion battery anodes are summarized and their energy storage mechanism is compared to transit...

“…In the first cycle, two intense reduction peaks in the cathodic scan occur at around0 .59 and 0.42 V, corresponding to the initial reduction of b-NiMoO 4 to Ni and Mo (NiMoO 4 + 8Li + + 8e À !Ni + Mo + 4Li 2 O) and NiO to Ni (NiO + 2Li + + 2e À !Ni + Li 2 O),c ombined with the formation of amorphousL i 2 O and SEI layers.

Ternary transition metal oxides (TTMOs) have attracted considerable attention for rechargeable batteries because of their fascinating properties. However, the unsatisfactory electrochemical performance originating from the poor intrinsic electronic conductivity and inferior structural stability impedes their practical applications. Here, the novel hierarchical porous NiO/β‐NiMoO4 heterostructure is fabricated, and exhibits high reversible capacity, superior rate capability, and excellent cycling stability in Li‐ion batteries (LIBs), which is much better than the corresponding single‐phase NiMoO4 and NiO materials. The significantly enhanced electrochemical properties can be attributed to its superior structural characteristics, including the large surface area, abundant pores, fast charge transfer, and catalytic effect of the intermediate product of metallic nickel. The NiO/β‐NiMoO4 heterostructure delivers a high capacity of 1314 mA h g−1 at 0.2 A g−1 after 100 cycles. Furthermore, even after 400 cycles at 1 A g−1, the reversible capacity remains at around 500 mA h g−1. These results indicate that the NiO/β‐NiMoO4 heterostructure shows great potential as an anode material for high‐performance LIBs.

International audienceCarbon-oxide and carbon-sulfide nanocomposites have attracted tremendous interest as the anode materials for Li and Na ion batteries. Such composites are fascinating as they often show synergistic effect compared to their singular components. Carbon nanomaterials are often used as the matrix due to their high conductivity, tensile strength, and chemical stability under the battery condition. Metal oxides and sulfides are often used as active material fillers because of their large capacity. Numerous works have shown that by taking one step further into fabricating nanocomposites with rational structure design, much better performance can be achieved. The present review aims to present and discuss the development of carbon-based nanocomposite anodes in both Li ion batteries and Na ion batteries. The authors introduce the individual components in the composites, i.e., carbon matrices (e.g., carbon nanotube, graphene) and metal oxides/sulfides; followed by evaluating how advanced nanostructures benefit from the synergistic effect when put together. Particular attention is placed on strategies employed in fabricating such composites, with examples such as yolk–shell structure, layered-by-layered structure, and composite comprising one or more carbon matrices. Lastly, the authors conclude by highlighting challenges that still persist and their perspective on how to further develop the technologies
