“…However, because of its high cost and toxicity, RuO 2 as an electrode material for supercapacitors in a commercial level is being lot more cogitated. Hence, transition metal (such as Fe, Co, Cu, Ni and Mn) oxides/hydroxides are under extensive investigation as alternate electrode materials for supercapacitors 15,28,29 . Among these metal oxides/hydroxide, Ni(OH) 2 is a potential candidate due to its elemental abundance (second most abundant element in the earth’s core), non-toxicity, easy preparation in various shapes at the nanoscale with excellent electrochemical performance like high theoretical specific capacity of 1041 C/g 25 .…”

Hydrated Ni(OH)2 and activated carbon based electrodes are widely used in electrochemical applications. Here we report the fabrication of symmetric supercapacitors using Ni(OH)2 nanosheets and activated carbon as positive and negative electrodes in aqueous electrolyte, respectively. The asymmetric supercapacitors stack connected in series exhibited a stable device voltage of 9.6 V and delivered a stored high energy and power of 30 mWh and 1632 mW, respectively. The fabricated device shows an excellent electrochemical stability and high retention of 81% initial capacitance after 100,000 charge-discharges cycling at high charging current of 500 mA. The positive electrode material Ni(OH)2 nanosheets was prepared through chemical decomposition of nickel hexacyanoferrate complex. The XRD pattern revealed the high crystalline nature of Ni(OH)2 with an average crystallite size of ~10 nm. The nitrogen adsorption-desorption isotherms of Ni(OH)2 nanosheets indicate the formation of mesoporous Ni(OH)2 nanosheets. The chemical synthesis of Ni(OH)2 results the formation of hierarchical nanosheets that are randomly oriented which was confirmed by FE-SEM and HR-TEM analysis. The negative electrode, activated porous carbon (OPAA-700) was obtained from orange peel waste. The electrochemical properties of Ni(OH)2 nanosheets and OPAA-700 were studied and exhibit a high specific capacity of 1126 C/g and high specific capacitance of 311 F/g at current density of 2 A/g, respectively. Ni(OH)2 nanosheets delivered a good rate performance and remarkable capacitance retention of 96% at high current density of 32 A/g.

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.

“…Ni-, Co-and Fe-based battery-type electrode materials are promising materials for high energy storage applications due to the low cost, environmental sustainability, intrinsic electronic conductivity, high capacity, good rate performance, long life span and high redox behavior. [12][13][14][15][16] For example, Wang et al fabricated a Ni 3 S 4 battery-type electrode supercapacitor with a specic capacitance of 898.5 C g À1 at 0.5 A g À1 current density. 17 Ni 3 S 2 /CdS exhibit a capacity of 545.6 C g À1 at the current density of 1 A g À1 with the capacitance retention of 103% aer 5000 cycles.…”
