“…Recently, metal molybdate (MMoO 4 and M 2 O 3 .nMoO 3 , M = metal) based electrodes have received significant interest in Li-ion batteries and supercapacitors due to their stable crystal structure and redox behaviour of metals (Ni, Co and Mn) in aqueous alkali electrolytes [5][6][7][8][9][10][11][12][13][14][15]. Especially, heterostructured MnMoO 4 /CoMoO 4 nanowires showed a SC of 187.1 F g -1 and excellent cycling stability [10].…”

This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. is analyzed by cyclic voltammetry and galvanostatic charge-discharge techniques. The effect of Na based aqueous electrolytes on capacitance of the Aurvillius type structured Bi 2 MoO 6 is investigated. As prepared γ-Bi 2 MoO 6 nanoplates provide the high specific capacitance (519 Fg -1 ) compared with the high-temperature monoclinic phase γ(H) Bi 2 MoO 6 in 1 M NaOH electrolyte. The obtained high specific capacitance of as prepared Bi 2 MoO 6 could be attributed to the decrease in particle size, increase in active sites, and nano plate-like structure of as prepared γ-Bi 2 MoO 6 .

“…EDLCs includes carbonaceous materials, such as activated carbon, carbide derived carbon, grapheme and carbon nanotubes [4][5][6][7] with a large surface area on which charge can reside but unfortunately due to low supercapacitor performance restricts its use as compared with pseudocapacitor. In pseudocapacitors the charge storage occurs through faradic reactions in which transition metal oxides and conducting polymers are used as electrode materials [8][9][10].Due to the fast redox reactions in transition metal oxide exhibits high-rate capacity, high rate capability, and cycling stability. RuO 2 is one of the prominent electro-active materials for pseudocapacitor but limits due its expensive nature, rare resources, and environmental toxicity.…”

Nanocrystalline cobalt oxide (Co 3 O 4 ) thin film electrodes were fabricated by spray pyrolysis method on conducting fluorine doped tin oxide (FTO) substrates using ammonia complexed with cobalt chloride (CoCl 2. 6H 2 O) solution. The structural and morphological properties of Co 3 O 4 electrodes were studied using X-ray diffraction (XRD) and scanning electron microscopy (SEM).The surface morphology study showed the film formation of porous surface with clusters. The electrochemical supercapacitive properties ofCo 3 O 4 electrodes were evaluated using cyclic voltammetry and galvanostatic charge-discharge method. The Co 3 O 4 electrodes showed maximum specific capacitance of 168 F/g in 1 M aqueous KOH electrolyte at the scan rate of 20 mV/s. The maximum specific energy and specific power of the cell are 2.2Wh/kg and 0.23 kW/kg, respectively.
