A novel spinel Co VO is studied as the Li-ion battery anode material and it is sandwiched with a 3D ultralight porous current collector (PCC) and amorphous carbon. Co VO demonstrates the high capacity and excellent cyclability because of the mixed lithium storage mechanisms. The 3D composite structure requires no binders and replaces the conventional current collector (Cu foil) with a 3D ultralight porous metal scaffold, yielding the high electrode-based capacity. Such a novel composite anode also enables the close adhesion of Co VO to the PCC scaffold. The resulting monolithic electrode has the rapid electron pathway and stable mechanical properties, which lead to the excellent rate capabilities and cycling properties. At a current density of 1 A g , the PCC and carbon sandwiched Co VO anode is able to deliver a stable reversible capacity of about 706.8 mAh g after 1000 cycles. Generally, this study not only develops a new Co VO anode with high capacity and good cyclability, but also demonstrates an alternative approach to improve the electrochemical properties of high capacity anode materials by using ultralight porous metallic current collector instead of heavy copper foil.

Recently, adopting carbon coating has drawn considerable attention for increasing the electrical conductivity and enhancing the stability of the electrode materials as elastic buffer supports upon cycling to improve the electrochemical performance. [27][28][29][30][31] Even through the volume changes may be effectively controlled by flexible substrates, this strategy is still limi ted in improving specific capacity and rate performance. Nanoengineering of ultrafine nanostructure (ultrafine nanoparticles or ultrafine nanosized subunits) has become the most powerful mean to tackle above challenge because they can increase the electrodeelectrolyte contact area, lower the absolute volume change, and shorten the distance for lithium-ion diffusion within the particles. [32,33] For instance, 3D mesoporous Co 3 O 4 networks composed of small Co 3 O 4 nanoparticles (5-10 nm) synthesized by Naiqin Zhao exhibit high specific capacity (1033 mA h g −1 at 0.1 A g −1 ) and remarkable rate capability. [34] Furthermore, robust and favorable ultrafine secondary nanoparticles would effectively accommodate the severe volume variation upon cycling and prevent self-aggregation of the ultrafine nanoscale subunits, thus leading to improved capacity retention and rate capability. For example, polydopamine-coated SnO 2 nanocrystals comprising SnO 2 nanoparticles (diameter ≈ 5 nm) developed by Lin and co-workers display excellent rate capability. [35] Nevertheless, the existing synthetic methods can only fabricate the ultrafine nanoparticles with exposed or mosaic structure which have disadvantages of inevitable aggregation and unstable nanostructure during long-term cycling; moreover, they are unsuitable for large-scale production. Hence, it is a great challenge to design and synthesize ultrafine carbon coating TMO subunit through a facile and one-pot method on a large scale.Along these lines, we develop a facile and novel one-pot approach for the first time to synthesize a series of highly uniform pomegranate-like TMO@nitrogen-doped carbon nanoclusters (TMO@N-C NCs) with a large scale production, which are organized by numerous of ultrafine TMO@N-C subunits (diameter ≈ 4 nm). This approach has been demonstrated to synthesize various pomegranate-like TMO@N-C NCs, including simple oxides such as Fe 3 O 4 , Mn 3 O 4 , NiO, and ZnO. Taking pomegranate-like Fe 3 O 4 @N-C NCs as an example, the pomegranate-like Fe 3 O 4 @N-C NCs with this unique nanostructure show excellent cycle stability and superior rate capacity Uniform pomegranate-like nanoclusters (NCs) organized by ultrafine transition metal oxide@nitrogen-doped carbon (TMO@N-C) subunits (diameter ≈ 4 nm) are prepared on a large scale for the first time through a facile, novel, and one-pot approach. Taking pomegranate-like Fe 3 O 4 @N-C NCs as an example, this unique structure provides short Li + /electron diffusion pathways for electrochemical reactions, structural stability during cycling, and high electrical conductivity, leading to superior electrochemical performance. The resulting...

“…Recent studies have improved the electrochemical performance by either synthesizing hybrid nanomaterials or modifying the material to structures such as hollow, porous, etc. [ 67,236–238 ] Li et al [ 239 ] proposed a net‐like SnS/C nanocomposite thin film, which is regarded as a stable skeleton; it maintained a discharge capacity of 542.3 mA h g −1 after 40 cycles. Deng and his colleagues [ 240 ] developed a coconut‐like single crystal SnS/C nanosphere in a limited nanospace through a micro‐evaporation‐plating strategy.…”

SnSx (x = 1, 2) compounds are composed of earth‐abundant elements and are nontoxic and low‐cost materials that have received increasing attention as energy materials over the past decades, owing to their huge potential in batteries. Generally, SnSx materials have excellent chemical stability and high theoretical capacity and reversibility due to their unique 2D‐layered structure and semiconductor properties. As a promising matrix material for storing different alkali metal ions through alloying/dealloying reactions, SnSx compounds have broad electrochemical prospects in batteries. Herein, the structural properties of SnSx materials and their advantages as electrode materials are discussed. Furthermore, detailed accounts of various synthesis methods and applications of SnSx materials in lithium‐ion batteries, sodium‐ion batteries, and other new rechargeable batteries are emphasized. Ultimately, the challenges and opportunities for future research on SnSx compounds are discussed based on the available academic knowledge, including recent scientific advances.
