For hybrid electric vehicles, supercapacitors are an attractive technology which, when used in conjunction with the batteries as a hybrid system, could solve the shortcomings of the battery. Supercapacitors would allow hybrid electric vehicles to achieve high efficiency and better power control. Supercapacitors possess very good power density. Besides this, their charge-discharge cycling stability and comparatively reasonable cost make them an incredible energy-storing device. The manufacturing strategy and the major parts like electrodes, current collector, binder, separator, and electrolyte define the performance of a supercapacitor. Among these, electrode materials play an important role when it comes to the performance of supercapacitors. They resolve the charge storage in the device and thus decide the capacitance. Porous carbon, conductive polymers, metal hydroxide, and metal oxides, which are some of the usual materials used for the electrodes in the supercapacitors, have some limits when it comes to energy density and stability. Major research in supercapacitors has focused on the design of stable, highly efficient electrodes with low cost. In this review, the most recent electrode materials used in supercapacitors are discussed. The challenges, current progress, and future development of supercapacitors are discussed as well. This study clearly shows that the performance of supercapacitors has increased considerably over the years and this has made them a promising alternative in the energy sector.

“…In bulk, AlH 3 decomposes at 100-150 • C and the kinetics are reasonably fast, but the high H 2 pressure required to achieve reversibility (10 GPa, 600 • C, 24 h; 10 GPa at 25 • C or 6 GPa at 300-380 • C by other accounts are all very high pressures) remains a hard obstacle to overcome (Table 12). Even so, mitigation of this drawback has been attempted by means of nanoconfinement [40,44,51,109,125,203,206,216,[226][227][228][229][230][231][232][233]. Some results are pure theoretical results concerning the catalytic activity of nano-AlH 3 [229] in the decomposition of 1,3,5,7-Tetranitro-1,3,5,7-tetrazocane, with simulated evolution of Al-clusters during the reaction [228], or decomposition of CH 3 NO 2 /nano-AlH 3 composite [232].…”

Hydrogen is the ultimate vector for a carbon-free, sustainable green-energy. While being the most promising candidate to serve this purpose, hydrogen inherits a series of characteristics making it particularly difficult to handle, store, transport and use in a safe manner. The researchers’ attention has thus shifted to storing hydrogen in its more manageable forms: the light metal hydrides and related derivatives (ammonia-borane, tetrahydridoborates/borohydrides, tetrahydridoaluminates/alanates or reactive hydride composites). Even then, the thermodynamic and kinetic behavior faces either too high energy barriers or sluggish kinetics (or both), and an efficient tool to overcome these issues is through nanoconfinement. Nanoconfined energy storage materials are the current state-of-the-art approach regarding hydrogen storage field, and the current review aims to summarize the most recent progress in this intriguing field. The latest reviews concerning H2 production and storage are discussed, and the shift from bulk to nanomaterials is described in the context of physical and chemical aspects of nanoconfinement effects in the obtained nanocomposites. The types of hosts used for hydrogen materials are divided in classes of substances, the mean of hydride inclusion in said hosts and the classes of hydrogen storage materials are presented with their most recent trends and future prospects.

“…Nanocatalysts with striking new catalytic performance, including enhanced reactivity and selectivity, have attracted ever-growing interests [1][2][3][4][5]. In the field of hydrogen storage, Ti-based catalysts are extensively investigated for hydrogen storage reaction of light metal hydrides [6][7][8][9][10], especially for sodium alanate, NaAlH4, a prototypical complex hydride with favourable thermodynamics and an acceptable gravimetric storage capacity [11][12][13][14]. In 1997, Bogdanović and Schwickardi reported that a few mol% of Ti alkoxides could effectively enhance reversible hydrogen storage by NaAlH 4 at moderate conditions [15].…”
