“…Surfactants are commonly used in the preparation of various electrode materials by a number of different techniques, such as chemical co-precipitation [13,14], liquid co-precipitation [15] as well as electrochemical deposition methods [16,17], and their use has been widely reported in the literature. Ghaemi et al [17] have reported that electrolytic MnO2 prepared in the laboratory in the absence of surfactant does not have properties appropriate for battery applications.…”

“…23,24 Ghaemi et al 24 have reported that electrolytic MnO 2 prepared in the laboratory in the absence of surfactant does not have properties appropriate for battery applications. On the other hand, the electrochemical behavior of EMD prepared in the presence of surfactants-namely, t-octyl phenoxy polyethoxyethanol (Triton X-100), cetyltrimethylammonium bromide (CTAB), or sodium n-dodecylbenzenesulfonate (SDBS)-is suitable for battery applications.…”

The dual effect of in-situ addition of anionic surfactants, sodium octyl sulfate (SOS), sodium dodecyl sulfate (SDS) and sodium tetradecyl sulfate (STS) on the microstructure and electrochemical properties of electrolytic manganese dioxide (EMD) produced from waste low grade manganese residue is discussed. X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), BET-surface area studies, thermogravimetry-differential thermal analysis (TG-DTA) and Fourier transform infrared spectroscopy (FTIR) were used to determine the structure and chemistry of the EMD. All EMD samples were found to contain predominantly γ-phase MnO 2 , which is electrochemically active for energy storage applications. FESEM images showed that needle, rod and flower shaped nano-particles with a porous surface and platy nano-particles were obtained in the case of EMD deposited with and without surfactant respectively. Thermal studies showed loss of structural water and formation of lower manganese oxides indicating high stability of the EMD samples. The cyclic voltammetry and charge -discharge characteristics implied the presence of surfactants enhances the energy storage within the MnO 2 structure. Addition of the surfactant at its optimum concentration greatly increased the EMD surface area, which in turn improved the cycle life of the EMD cathode. EMD obtained in the presence of 25, 50, 25 ppm of SOS, SDS, and STS respectively showed an improved cycle life relative to the EMD obtained in the absence of surfactant. EMD obtained without surfactant showed a capacity fade of 20 mAh g −1 within 15 discharge-charge cycles, while surfactant modified samples showed stable cyclic behavior of capacity 95 mAh g −1 even after 15 cycles. Global demand for new energy materials and energy storage devices is increasing rapidly and in parallel with the quest for alternative energy resources. Substantial research and development effort continues to be invested in the synthesis of an economically viable, ecofriendly storage device from a natural source. Among the various energy storage devices, alkaline rechargeable batteries have become the ultimate choice for energy storage systems in the portable electronics market as well as electric transport systems.1-3 Worldwide research and development programs in this area have been underway for more than a century, 2 with most attention focused on Zn-Mn, Ni-Cd, Ni-Fe, Ni-Zn, Ni-MH, and Li-ion rechargeable systems.4 Among these, ZnMn alkaline batteries have held a strong position in the battery market for many decades.Manganese dioxide, used as the active material in Zn-MnO 2 batteries, can be prepared both by chemical synthesis (chemical manganese dioxide, CMD) or electrochemical deposition (electrodeposited manganese dioxide, EMD) methods. Adequate primary Mn resources are available from which manganese dioxide can be produced, but the rapidly growing demand for manganese/manganese oxide has made it increasingly important to develop processes for economic recovery of manganese from low-grade mang...

“…16,17 In this regard, many researchers have attempted to overcome these limitations and boost the supercapacitor properties of Co(OH) 2 by using new methods and strategies for synthesis and modication of individual structures [18][19][20][21] or hybrid structures of Co(OH) 2 . [22][23][24][25][26] In the same vein, using carbon-based materials in combination with Co(OH) 2 is one of these strategies to take advantage of synergistic effects and to improve supercapacitor properties of Co(OH) 2 . Among carbonaceous materials, graphene has attracted intense interest because of its unique electrical and mechanical properties, such as high electrical conductivity (10 3 to 10 4 S m…”

In this study, Co(OH) 2 -reduced graphene oxide has been synthesized using a simple and rapid one-step cathodic electrodeposition method in a two electrode system at a constant current density on a stainless steel plate, and then characterized as a supercapacitive material on Ni foam. The composites were characterized by FT-IR, X-ray diffraction, scanning electron microscopy, and cyclic voltammetry using a galvanostatic charge/discharge test.The feeding ratios of the initial components for electrodeposition had a significant effect on the structure and electrochemical performance of the Co(OH) 2 -reduced graphene oxide composite. The results show that the 1 : 4 (w/w) ratio of GO : CoCl 2 $6H 2 O was optimum and produced an intertwined composite structure with impressive supercapacitive behavior. The specific capacitance of the composite was measured to be 734 F g À1 at a current density of 1 A g À1. Its rate capability was $78% at 20 A g À1 and its capacitance retention was 95% after 1000 cycles of charge-discharge. Moreover, its average energy density and power density were calculated to be 60.6 W h kg À1 and 3208 W kg À1, respectively. This green synthesis method enables a rapid and low-cost route for the large scale production of Co(OH) 2 -reduced graphene oxide nanocomposite as an efficient supercapacitor material.
