“…Similarly, Bilen et al [37] achieved 90% LiBH 4 purity from the reaction of LiBO 2 with MgH 2 by ball milling. In addition, ball milling is known to be an extremely powerful and versatile technique for the treatment of waste materials [45][46][47][48][49]. These works clearly show that ball milling is a suitable method to produce LiBH 4 and NaBH 4 from mixtures of LiBO 2 or NaBO 2 and MgH 2 , respectively.…”

Lithium borohydride (LiBH4) and sodium borohydride (NaBH4) were synthesized via mechanical milling of LiBO2, and NaBO2 with Mg–Al-based waste under controlled gaseous atmosphere conditions. Following this approach, the results herein presented indicate that LiBH4 and NaBH4 can be formed with a high conversion yield starting from the anhydrous borates under 70 bar H2. Interestingly, NaBH4 can also be obtained with a high conversion yield by milling NaBO2·4H2O and Mg–Al-based waste under an argon atmosphere. Under optimized molar ratios of the starting materials and milling parameters, NaBH4 and LiBH4 were obtained with conversion ratios higher than 99.5%. Based on the collected experimental results, the influence of the milling energy and the correlation with the final yields were also discussed.

“…The maximum value of heat storage was~714 kJ/kg under the conditions of absorption temperature at 150 • C and supplying hydrogen pressure of 20 bar. Recently, the waste Mg-Al based alloys were used as the starting materials for producing a high quality hydrogen storage system by industrial mills [77]. The as-prepared samples showed good hydrogen sorption capacity (~6 wt %) and fast hydrogenation kinetics, which were promising to apply for TES.…”

Utilization of renewable energy such as solar, wind, and geothermal power, appears to be the most promising solution for the development of sustainable energy systems without using fossil fuels. Energy storage, especially to store the energy from fluctuating power is quite vital for smoothing out energy demands with peak/off-peak hour fluctuations. Thermal energy is a potential candidate to serve as an energy reserve. However, currently the development of thermal energy storage (TES) by traditional physical means is restricted by the relatively low energy density, high temperature demand, and the great thermal energy loss during long-period storage. Chemical heat storage is one of the most promising alternatives for TES due to its high energy density, low energy loss, flexible temperature range, and excellent storage duration. A comprehensive review on the development of different types of Mg-based materials for chemical heat storage is presented here and the classic and state-of-the-art technologies are summarized. Some related chemical principles, as well as heat storage properties, are discussed in the context. Finally, some dominant factors of chemical heat storage materials are concluded and the perspective is proposed for the development of next-generation chemical heat storage technologies.

“…However, its practical application is limited due to its thermodynamic stability and poor kinetic performance. To overcome these weaknesses, methods such as alloying (Oh et al, 2016;Hardian et al, 2018;Li et al, 2018), nanocrystallization (Wagemans et al, 2005;Li et al, 2007) and the addition of catalysts has been employed (Cui et al, 2014;Huang et al, 2017;Zhang et al, 2017;Wang et al, 2019;Yang et al, 2019).…”

To improve the hydrogen storage properties of Mg/MgH 2 , a Ni and TiO 2 co-doped reduced graphene oxide [(Ni-TiO 2)@rGO] nanocomposite is synthesized by a facile impregnation method and introduced into Mg via ball milling. The results demonstrated that the dispersive distribution of Ni and TiO 2 with a particle size of 20-200 nm in the reduced graphene oxide matrix led to superior catalytic effects on the hydrogen storage properties of Mg-(Ni-TiO 2)@rGO. The initial hydrogenation/dehydrogenation temperature for Mg-(Ni-TiO 2)@rGO decreased to 323/479 K, 75/84 K lower than that of the additive-free sample. The hydrogen desorption capacity of the Mg-(Ni-TiO 2)@rGO composite released 1.47 wt.% within 120 min at 498 K. When the temperature was increased to 523 K, the hydrogen desorption capacity increased to 4.30 wt.% within 30 min. A hydrogenation/dehydrogenation apparent activation energy of 47.0/99.3 kJ•mol −1 was obtained for the Mg-(Ni-TiO 2)@rGO composite. The improvement in hydrogenation and dehydrogenation for the Mg-(Ni-TiO 2)@rGO composite was due to the reduction of the apparent activation energy by the catalytic action of (Ni-TiO 2)@rGO.
