Negative electrodes for supercapacitors with good performance using conductive bismuth-catecholate metal–organic frameworks

“…To fulfil society's rising energy needs and enable the integration of renewable energy sources into energy networks, the development of energy storage technology is essential. [1][2][3] Supercapacitors are regarded as one of the most promising candidates for energy storage as a result of their high power density, safe operation, and long cycle life. [4][5][6] Supercapacitors usually store charge by double-layer physical adsorption and/ or faradaic reaction on the surfaces or sub-surface regions of their electrodes.…”

Electro Fenton's reaction coupled Zn-air battery for in situ pollutant degradation

“…Renewable energy-assisted energy storage and conversion devices such as fuel cells, batteries and super capacitors are projected as promising alternatives to fossil fuel-based energy chains. [1][2][3][4][5][6][7][8] As of now, the primary roles of electrochemical energy devices are mainly confined to the on-demand electricity production. 8,9 Introducing a novel dimension to their functionality will immensely enrich the chemistry of energy storage and conversion.…”

An air chargeable hydrogen battery by reversible electrochemical trapping of the protons

“…8,9 Though Li-ion batteries have revolutionized the portable electronic market for more than a decade, there are concerns related to the availability of raw materials and their cost. 4,7,[10][11][12][13] To overcome the growing energy demands, and the challenges associated with carbonbased energy economy and conventional energy storage technologies, a transition to a carbon-neutral energy economy is inevitable, which demands the development of environmentally friendly and affordable energy storage devices. [2][3][4][5][6][7][10][11][12][13][14][15][16][17] All of these mandate the focus on hydrogen economy, which refers to the use of dihydrogen as a fuel whose combustion in principle should be carbon neutral.…”
