The application of metal oxides and sulfides for lithium‐ion batteries (LIBs) is hindered by the limited Li+ diffusion kinetics and inevitable structural damage. Pseudocapacitance for electrochemical lithium storage provides an effective and competitive solution for developing electrode materials with large capacity, high rate capability, and stability. Herein, a composite composed of VS4 nanoplates tightly bound to carbon nanotubes (VS4/CNTs) is developed to demonstrate pseudocapacitance‐assisted lithium storage. The texture of the assembled VS4 nanoplates supplies efficient electrolyte/ion diffusion, as well as exposed surface for pseudocapacitive behavior. The effective coupling between VS4 and CNTs ensures fast electron transfer and high stability. The VS4/CNTs anode exhibits high capacity of 1144 mAh g−1 at 0.1 A g−1, superior cycling stability (capacity retention of 100 % at 1 A g−1 after 400 cycles), and good rate capability. The pseudocapacitive behavior plays an important role in determining the excellent electrochemical properties, contributing to the increased charge rate and reaching as high as 42 % of the total charge at a scan rate of 1 mV s−1. This study demonstrates the potential application of metal sulfides with pseudocapacitive contribution in LIBs. [ABSTRACT FROM AUTHOR]

Nanoarray electrodes with highly capacitive materials and specific architectures are hopeful to realize advanced supercapacitor performance. The nickel foam (NF) supported hierarchical nanosheet array electrode is fabricated through a template route toward excellent capacitive supercapacitor. The hierarchical nanosheet array weaved with Ni(OH)2‐MnO2 nanowires provides multiple advantages for porous feature, high surface area, and fast charge transfer. The neighbored Ni(OH)2‐MnO2 supplies lattice fringes distortion as additional active sites as well as synergism, for improved capacitive performances. As expected, the Ni(OH)2‐MnO2/NF electrode manifests high specific capacitance of 14.7 F cm−2 at 2.5 mA cm−2 and good cyclic stability, making it hopeful for highly capacitive supercapacitor application. Hierarchical nanosheet array weaved by Ni(OH)2‐MnO2 nanowires is fabricated on nickel foam as integrated electrode for high‐capacity supercapacitor. The excellent performances are assigned to the structure benefits of hierarchical nanosheets, including high surface area, lattice fringes distortion, and shortened charge diffusion, as well as synergism between neighbored crystals hybridization.
