## Description

- description: Tungsten trioxide (WO3) is promising electrochromic materials applied
    to smart windows for the containment of CO2 emission, energy crisis, and climate
    change. It incidentally manifests itself as potential supercapacitive materials
    for energy storage that accelerates the applications of electric vehicles and
    portable electronics and complements current battery technologies. Unlike conventional
    capacitors, supercapacitors implement the electrochemical double layer capacitor
    and pseudocapacitor mechanisms to raise storage capabilities on a limited area
    thus the nanoporous structure can be utilized to boost capacities. Here we present
    preparation of nanoporous materials of nanoparticulate WO3/MoO3 films using green
    technologies of electro-exploding wire and spray coating techniques. Nanoporous
    structures of the films are simply extended with an increase of film thickness.
    Their energy storage capabilities are explored using cyclic voltammetry and galvanostatic
    charge-discharge measurements. It is unveiled that diffusion coefficients of ion
    intercalation and deintercalation exponentially increase with an increase of film
    thickness and the highest areal capacitance of 87.3 mF/cm2 is achieved at a discharging
    current of 0.1 mA/cm2. In addition, the nanoparticulate WO3/MoO3 films present
    a good charging-discharging retention ability, up to 67%. Such impressive energy
    storage capabilities of WO3/MoO3 composite films can be exploited for high-performance
    supercapacitive applications.
