“…Rechargeable lithium-ion batteries (LIBs) are one of the most important energy storage devices in microchips, cell phones, electric vehicles (EVs), and hybrid electric vehicles (HEVs) (Whittingham, 2004; Armand and Tarascon, 2008; Zheng et al, 2015; Ou et al, 2017; Pan et al, 2017a,b; Yang et al, 2017). Layer-structured LiCoO 2 has been extensively studied and largely used as commercial cathode materials due to their high working potential, high energy density and good cycling performance.…”

Single crystalline fork-like potassium vanadate (K2V8O21) has been successfully prepared by electrospinning method with a subsequent annealing process. The as-obtained K2V8O21 forks show a unique layer-by-layer stacked structure. When used as cathode materials for lithium-ion batteries, the as-prepared fork-like materials exhibit high specific discharge capacity and excellent cyclic stability. High specific discharge capacities of 200.2 and 131.5 mA h g−1 can be delivered at the current densities of 50 and 500 mA g−1, respectively. Furthermore, the K2V8O21 electrode exhibits excellent long-term cycling stability which maintains a capacity of 108.3 mA h g−1 after 300 cycles at 500 mA g−1 with a fading rate of only 0.043% per cycle. The results demonstrate their potential applications in next-generation high-performance lithium-ion batteries.

Sodium ion batteries (SIBs) have been regarded as a prime candidate for large-scale energy storage, and developing high performance anode materials is one of the main challenges for advanced SIBs. Novel structured Sn-MoS -C@C microspheres, in which Sn nanoparticles are evenly embedded in MoS nanosheets and a thin carbon film is homogenously engineered over the microspheres, have been fabricated by the hydrothermal method. The Sn-MoS -C@C microspheres demonstrate an excellent Na-storage performance as an anode of SIBs and deliver a high reversible charge capacity (580.3 mAh g at 0.05 Ag ) and rate capacity (580.3, 373, 326, 285.2, and 181.9 mAh g at 0.05, 0.5, 1, 2, and 5 Ag , respectively). A high charge specific capacity of 245 mAh g can still be achieved after 2750 cycles at 2 Ag , indicating an outstanding cycling performance. The high capacity and long-term stability make Sn-MoS -C@C composite a very promising anode material for SIBs.

“…A possible way to tailor the L-TMD materials with enhanced conductivity and good control over the surface area during cycling is to incorporate the 0D moieties (noble metal, and metal/metal oxide (NPs) etc.) in the layered structures which can provide charge carriers for enhanced conductivity and effectively limit the restacking of L-TMDs [33][34][35][36][37][38]. Such incorporation acts as a spacer to support the material, making the active surfaces of L-TMD accessible for electrolyte penetration lithiation/de-lithiation process improving electrochemical response of the LIBs.…”

“…The MoS 2 -C hybrids were fabricated from Na 2 MoO 4 .2H 2 O, NH 2 CSNH 2 and glucose as source material by hydrothermal method with subsequent heat treatment in Ar atmosphere. The resultant product was then subjected to another hydrothermal reaction in presence of Sn precursor followed by final calcination in Ar [37].…”

Abstract:With an ever increasing energy demand and environmental issues, many state-of-the-art nanostructured electrode materials have been developed for energy storage devices and they include batteries, supercapacitors and fuel cells. Among these electrode materials, L-TMD (layered transition metal dichalcogenide) nanosheets (especially, S (sulfur) and Se (selenium) based dichalcogenides) have received a lot of attention due to their intriguing layered structure for enhanced electrochemical properties. L-TMD composites have recently been investigated not only as a main charge storage specie but also, as a substrate to hold the active specie. This review highlights the recent advancements in L-TMD composites with 0D (0-dimensional), 1D, 2D, 3D and various forms of carbon structures and their potential applications in LIB (lithium ion battery) and SIB (sodium ion battery).
