Modified Borohydrides for Reversible Hydrogen Storage (2)
This paper reports the results in the effort to destabilize lithium borohydride for reversible hydrogen storage. A number of metals, metal hydrides, metal chlorides and complex hydrides were selected and evaluated as the destabilization agents for reducing dehydriding temperature and generating dehydriding-rehydriding reversibility. It is found that some additives are effective. The Raman spect...
متن کاملDestabilized LiBH4/MgH2 for reversible hydrogen storage
DOE and FreedomCAR technical targets of 6.0 and 9.0 wt.% are set forth capacities to realize a “holy grail” for hydrogen storage systems for 2010 and 2015 respectively. Alkali metal complex hydrides with high theoretical hydrogen capacity, for example: LiBH4 (18 wt.%), are being investigated for their properties to store large quantities of hydrogen. The catalytic doping of SiO2, seems to enhan...
متن کاملUsing first principles calculations to identify new destabilized metal hydride reactions for reversible hydrogen storage.
Hydrides of period 2 and 3 elements are promising candidates for hydrogen storage, but typically have heats of reaction that are too high to be of use for fuel cell vehicles. Recent experimental work has focused on destabilizing metal hydrides through mixing metal hydrides with other compounds. A very large number of possible destabilized metal hydride reaction schemes exist, but the thermodyna...
متن کامل3D intra-stacked CoO/carbon nanocomposites welded by Ag nanoparticles for high-capacity, reversible lithium storage.
A wet-chemical, facile strategy is proposed for forming three-dimensional intra-structured nanocomposites to facilitate the development of high performance anodes for lithium ion batteries. The nanocomposites are composed of cobalt oxide nanoparticles, reduced graphene oxides, and Ag nanoparticles, and all the constituent materials are incorporated homogenously in a layer-by-layer structured ge...
متن کاملMg2FeH6-based Nanocomposites with High Capacity of Hydrogen Storage Processed by Reactive Milling
The compound Mg 2 FeH 6 was synthesized from a 2Mg-Fe mixture in a single process through high-energy ball milling under hydrogen atmosphere at room temperature. The complex hydride was prepared from Mg powder and granulated or powdered Fe using a planetary mill. The phase evolution during different milling times was performed by X-rays diffraction technique. The dehydrogenation behavior of the...
