Development of high storage capacity complex hydrides for reversible hydrogen storage
(2013)
In this study, novel light weight complex hydrides for reversible hydrogen storage are developed and synthesized. Metal hydrides are generally known to have a good hydrogen storage capacity but possess slow kinetics, ...
Investigation of Catalytic Effects and Compositional Variations in Desorption Characteristics of LiNH2-nanoMgH2
(2017)
LiNH2 and a pre-processed nanoMgH2 with 1:1 and 2:1 molar ratios were mechanochemically milled in a high-energy planetary ball mill under inert atmosphere, and at room temperature and atmospheric pressure. Based on the ...
Spillover enhancement for hydrogen storage by Pt doped hypercrosslinked polystyrene
(Elsevier Ltd, 2012)
High surface area physisorption materials are of interest for room temperature (RT) hydrogen storage enhancement by spillover. In this study, six different commercially available hypercrosslinked polystyrenes were screened ...
Investigation of polyaniline nanocomposites and cross-linked polyaniline for hydrogen storage
(Advanced Materials Research, 2012)
One of the biggest challenges for the commercial application of existing hydrogen storage materials is to meet the desired high volumetric and gravimetric hydrogen storage capacity and the ability to refuel quickly and ...
Volumetric Hydrogen Sorption Measurements − Uncertainty error analysis and the importance of thermal equilibration time
(2013-02-06)
Abstract
The design of a volumetric measurement apparatus is studied by means of an uncertainty analysis to provide guidelines for optimum hydrogen sorption measurements. The reservoir volume should be as small as possible ...
Degradation Mechanisms in Li-ion Batteries: A State-of-the-Art Review
(John Wiley & Sons, Ltd., 2017)
One of the most prominent energy storage technologies which are under continuous development, especially for mobile applications, is the Li‐ion batteries due to their superior gravimetric and volumetric energy density. ...
Reversible Hydrogen Storage in the Li-Mg-N-H System – The effects of Ru doped single walled carbon nanotubes on NH3 emission and kinetics
(Elsevier Ltd, 2013)
In this study, the LiNH2–MgH2 (2:1.1) complex hydride system (Li–Mg–N–H is investigated in terms of hydrogen ab/desorption kinetics and the concomitant NH3 emission levels. By selecting more intense ball milling parameters, ...
In-situ atomic force microscopy analysis of morphology and particle size changes in LiFePO4 cathode
(2014)
Li-ion batteries offer great promise for future plug-in hybrid electric vehicles (PHEVs) and pure electric vehicles (EVs). One of the challenges is to improve the cycle life of Li-ion batteries which requires detailed ...
A novel nitrogen rich porous aromatic framework for hydrogen and carbon dioxide storage
(2013)
A nitrogen rich, p-phenylenediamine based, porous aromatic framework (NPAF) with 1790 m2 g−1 BET surface area has been synthesized by using a Yamamoto coupling technique. The NPAF has shown a hydrogen uptake of 1.87 and ...
Metal Hydrides used for Hydrogen Storage, in Nanostructured Materials for Next-Generation Energy Storage and Conversion
(2017)
This chapter discusses about metal hydride technologies for on-board reversible hydrogen storage applications. The metal hydrides such as intermetallic alloys and solid solutions have interstitial vacancies where atomic ...
