Abstract
To improve the hydrogen-storage properties of Mg₂Ni, LiBH₄ was added by milling in hydrogen atmosphere (reactive mechanical milling, RMM). Mg₂Ni-10LiBH₄ was prepared with a composition of 90 wt% Mg₂Ni + 10 wt% LiBH₄. The quantity of released hydrogen (H_r) versus temperature T curve for Mg₂Ni10LiBH₄ was obtained by heating at..... More

Abstract
VCl₃ (vanadium (III) chloride) was selected as an additive to Mg to increase the hydrogenation and dehydrogenation rates and the hydrogen storage capacity of Mg. Instead of MgH₂, Mg was used as a starting material since Mg is cheaper than MgH₂. Samples with a composition of 95 wt% Mg +..... More

Abstract
The dehydrogenation rates of graphene-added Mg (named Mg-5graphene) were very low at 573 K and 593 K. Ni was added to increase the dehydrogenation rates of graphene-added Mg. Samples (designated as Mg-2.5Ni-2.5graphene) with a composition of 95 wt% Mg + 2.5 wt% Ni + 2.5 wt% graphene were prepared by..... More

Abstract
In the present work, MgH2 was doped with Zn(BH4)2, Ni, and/or Ti to improve its hydrogen absorption and release features. Samples were prepared by grinding in a planetary ball mill in a hydrogen atmosphere. To increase the hydrogen absorption and release rates without significantly sacrificing hydrogenstorage capacity the additive percentages..... More

Abstract
In the present work, we selected a polymer, polyvinylidene fluoride (PVDF), as an additive to improve the hydrogenation and dehydrogenation properties of Mg. 95 wt% Mg + 5 wt% PVDF (designated Mg-5PVDF) samples were prepared via milling in hydrogen atmosphere (reactive milling), and the hydrogenation and dehydrogenation characteristics of the.....

Abstract
In our previous work, samples with a composition of 95 wt% Mg + 5 wt% CMC (Carboxymethylcellulose, Sodium Salt, [C₆H₇O₂(OH)_x(C₂H₂O₃Na)_y]_n) (named Mg-5 wt%CMC) were prepared through hydride-forming milling. Mg-5 wt%CMC had a very high hydrogenation rate but a low dehydrogenation rate. Addition of Ni to Mg is known to increase..... More

Abstract
TaF₅ and VCl₃ were chosen as additives to enhance the hydrogen uptake and release rates of Mg. The total content of the additives was not more than 10 wt% since too high content reduces the fraction of Mg and thus the hydrogen storage capacity of the alloys. Samples with compositions..... More

Abstract
To improve the hydrogen uptake and release properties of magnesium (Mg), five weight percent of graphene was added to pre-milled Mg by milling in hydrogen (reaction-involving milling). The hydrogen uptake and release properties of the graphene-added Mg (named Mg-5graphene) were investigated. Premilling of Mg (for 24 h) and then adding..... More

Abstract
The addition of CMC (Carboxymethylcellulose, Sodium Salt) may improve the hydriding and dehydriding properties of Mg since it has a relatively low melting point and the melting of CMC during transformation-involving milling may put the milled samples in good states to absorb and release hydrogen rapidly. Samples with compositions of..... More

Abstract
Samples with compositions of 99 w/o MgH₂+1 w/o Zn(BH₄)₂ (designated MgH_2-1Zn(BH₄)₂) and 96 w/o MgH₂+2 w/o Zn(BH₄)₂₊2 w/o Ni (designated MgH_2-2Zn(BH₄)_2-2Ni) were prepared by milling in a planetary ball mill in a hydrogen atmosphere (reaction-involving milling). The hydrogen release properties of MgH_2- 1Zn(BH₄)₂ and MgH_2-2Zn(BH₄)_2-2Ni were compared. A larger quantity..... More

Abstract
In this work, MgH₂, Mg₂Ni, and Ni were added to Mg in order to improve the hydrogen-storage properties of Mg. A 84 wt% Mg + 10 wt% MgH₂ + 5 wt% Mg₂Ni + 1 wt% Ni sample (designated the Mg-based sample) was prepared by milling under a hydrogen atmosphere in..... More

Abstract
In this work, Mg₂Ni and Ni were added to MgH₂ in order to improve the hydrogen-storage properties of Mg. A 94 wt% MgH₂+5 wt% Mg₂Ni+1wt% Ni (named 94MgH₂+5Mg₂Ni+1Ni) sample was prepared by milling in a hydrogen atmosphere in a planetary ball mill for 5 h. The Mg₂Ni was hydrided during..... More

Abstract
Abstract: In this work, Zn(BH₄)₂ was added to improve the hydrogen-storage properties of MgH₂. A 99 wt% MgH₂+1 wt% Zn(BH₄)₂ sample was prepared by milling in a planetary ball mill in a hydrogen atmosphere. The proportion of the added Zn(BH₄)₂ was small (1 wt%) in order to increase hydriding and..... More

Abstract
In this work, niobium (V) fluoride was selected as an additive to heighten the hydrogen sorption rates of Mg. Specimens of pure Mg, 5 wt% niobium fluoride－added Mg, and 10 wt% niobium fluoride-added Mg were prepared by planetary ball milling in hydrogen. The hydrogen sorption properties of the specimens were..... More
