“…Like metal oxide conversion materials, polyoxometalate nanomaterial has numerous advantages over bulk phase material, hence, several authors have studied and reported polyoxometalate clusters, nanostructures, and nanomaterials in the literature . Molybdenum involved composites such as CoMoO 4 , Mn 2 Mo 3 O 8 , FeMoO 4 , NiMoO 4 , and MnMoO 4 have considered as battery anode material because of the synergistic effects of different metal elements and unique physical/electrochemical properties for energy storage applications.…”

Flower‐like Cu3[MoO4]2O microspheres have been synthesized by using a sequential process from lindgrenite (Cu3(MoO4)2(OH)2). Lindgrenite nanoflowers were synthesized through a simpler route by using an aqueous chemical precipitation technique at room temperature without any surfactants or template. Subsequently, 3D flower‐like Cu3[MoO4]2O microspheres have been synthesized by annealing at 300 °C for 2 h from lindgrenite (Cu3(MoO4)2(OH)2). From the XRD pattern, FTIR spectrum, SEM and TEM analysis, flower‐like Cu3[MoO4]2O (ca. 5 μm) microspheres have been obtained, which were assembled from 3–4 nm thick nanosheets with an orthorhombic structure. Application of 3D flower‐like microspheres as an anode material for lithium‐ion batteries (LIBs) has been investigated and the possible electrochemical mechanism is analyzed. Electrochemical characterization of the Cu3[MoO4]2O nanoflowers as an anode material for LIBs has exhibited good cycle stability and a high coulombic efficiency during operation. The electrochemical activity was attributed to the unique structure of the Cu3[MoO4]2O microspheres, which provide more active sites for Li‐ion storage as well as a reduced transfer resistance. This work has explored a simple synthesis strategy for the synthesis of flower‐like Cu3[MoO4]2O microspheres without templates, additives, or surfactants, which exhibit a basis for not only high electrochemical performance in reversible Li storage, but also cycle stability.

“…Although substantial progress has been made with CP‐based binary composites as pseudocapacitor materials, their electrochemical properties such as conductivity, power and energy density, as well as cycling stability still cannot reach the maximum possible levels . Currently, many researchers have focused their attention on CP/metal oxide/carbon ternary composites, such as PANi/NiMoO 4 /carbon‐cloth, CNT/PPy/MnO 2 , and Ni/PPy/MnO 2 . With the continuous study of conductive polymers, we believe that we could continue to approach or even reach the maximum possible level of electrochemical performance in the future.…”

Among the various energy-storage systems, lithium-ion capacitors (LICs) are receiving intensive attention due to their high energy density, high power density, long lifetime, and good stability. As a hybrid of lithium-ion batteries and supercapacitors, LICs are composed of a battery-type electrode and a capacitor-type electrode and can potentially combine the advantages of the high energy density of batteries and the large power density of capacitors. Here, the working principle of LICs is discussed, and the recent advances in LIC electrode materials, particularly activated carbon and lithium titanate, as well as in electrolyte development are reviewed. The charge-storage mechanisms for intercalative pseudocapacitive behavior, battery behavior, and conventional pseudocapacitive behavior are classified and compared. Finally, the prospects and challenges associated with LICs are discussed. The overall aim is to provide deep insights into the LIC field for continuing research and development of second-generation energy-storage technologies.

Advanced materials and technologies for supercapacitors used in energy conversion and storage: a review

Supercapacitors are increasingly used for energy conversion and storage systems in sustainable nanotechnologies. Graphite is a conventional electrode utilized in Li-ion-based batteries, yet its specific capacitance of 372 mA h g −1 is not adequate for supercapacitor applications. Interest in supercapacitors is due to their high-energy capacity, storage for a shorter period and longer lifetime. This review compares the following materials used to fabricate supercapacitors: spinel ferrites, e.g., MFe 2 O 4 , MMoO 4 and MCo 2 O 4 where M denotes a transition metal ion; perovskite oxides; transition metals sulfides; carbon materials; and conducting polymers. The application window of perovskite can be controlled by cations in sublattice sites. Cations increase the specific capacitance because cations possess large orbital valence electrons which grow the oxygen vacancies. Electrodes made of transition metal sulfides, e.g., ZnCo 2 S 4 , display a high specific capacitance of 1269 F g −1 , which is four times higher than those of transition metals oxides, e.g., Zn-Co ferrite, of 296 F g −1. This is explained by the low charge-transfer resistance and the high ion diffusion rate of transition metals sulfides. Composites made of magnetic oxides or transition metal sulfides with conducting polymers or carbon materials have the highest capacitance activity and cyclic stability. This is attributed to oxygen and sulfur active sites which foster electrolyte penetration during cycling, and, in turn, create new active sites.
