Techno-economic understanding of Indian energy-storage market: A perspective on green materials-based supercapacitor technologies

Construction of thickness-controllable bimetallic sulfides/reduced graphene oxide as a binder-free positive electrode for hybrid supercapacitors

“…The fabricated electrodes were activated by 50 cycles of the CV technique from 0 to 0.5 V at a 50 mV s −1 scan rate before taking the data due to unstable capacitive performance. Aerwards, the CV measurements were analyzed at different scan rates (5,10,20,40, and 50 mV s −1 ) with a potential window from 0 V to 0.5 V followed by the GCD measurements with the same voltage window for various current densities (1-20) A g −1 . Finally, the EIS measurements were carried out at frequencies ranging from 0.1 to 10 5 Hz using the open circuit potential (OCP) with an amplitude of 5 mV.…”

“…3 However, supercapacitors and batteries are more reliable and effective in this regard. [4][5][6] Based on the electrochemical energy conversion meaning, non-conventional energy sources have been utilized in portable electronic devices including supercapacitors (SCs), fuel cells (FCs), solar cells, and batteries. 7,8 Fuel cells use electrochemical processes with an oxidant (typically oxygen) to transform chemical energy from an external fuel like hydrocarbons, hydrogen, or alcohol into electrical energy.…”

Role of Different Catalysts on a Direct Growth Carbon Nanotube for Supercapacitor Electrodes

“…Thus, renewable wind, solar, geothermal energies, and so forth are considered as alternative sources of energy consumption. Nevertheless, such energy sources are more expensive, have limited storage capabilities, are not entirely carbon-free, and are not environmentally friendly. , Therefore, research is increasingly focused on finding low-cost, highly reliable energy-storage, carbon-free, eco-friendly batteries, supercapacitors, and fuel cell energy devices . Supercapacitors are also known as ultra-capacitors and electrochemical capacitors.…”

Three-dimensional ternary NixCuyZnz(CO3)(OH)2 electrodes for supercapacitors: electrochemical properties and applications

“…1,2 Electric/hybrid vehicles that produce renewable energy from sunlight, wind, or geothermal heat as alternative energy sources, with significantly lower carbon dioxide emissions, are being researched and developed. 3,4 However, the supply and demand of renewable energy vary, and the energy supply is low. Hence, devices that can stably store the energy generated by renewable sources are required.…”
