Metal dodecaborate, widely regarded as an obstacle of the rehydrogenation of high-density hydrogen storage materials metal borohydrides M(BH4)(n), is generally synthesized using liquid-phase process followed by a careful dehydration process. In this study, we propose a new and facile solvent-free synthesis process of dodecaborates using B10H14 with a low melting point of 99.6 degrees C as a boron source. As a case study, our first challenge focused on the syntheses of anhydrous M2B12H12 (M = Li, Na, and K) by heat treatment of starting materials (a) 2MH + 1.2B(10)H(14) or (b) 2MBH(4) + B10H14 at 200-450 degrees C conditions, which have been proved to be successful for the first time by X-ray diffraction (XRD), Raman, and NMR analysis. Starting materials (b) 2MBH(4) + B10H14 shows better reactivity than that of (a) 2MH + 1.2B(10)H(14), which demonstrates that synthesis of anhydrous M2B12H12 by heat treatment of 2MBH(4) + B10H14 is a feasible solvent-free process.

Summary: In this study, chitosan-coated PLGA microspheres with rough surface and hollow structure were successfully prepared using a modified method. These microspheres can be used as drug carriers to improve drug loading efficiency and anticancer effect, and reduce drug administration frequency. The chitosan-modified microspheres showed prolonged anticancer activity and promoted apoptosis, suggesting their potential application in liver cancer treatment.

Anion-Regulated Weakly Solvating Electrolytes for High-Voltage Lithium Metal Batteries

Zhipeng Jiang, Jisheng Mo, Chen Li, Hai-Wen Li, Qingan Zhang, Ziqi Zeng, Jia Xie, Yongtao Li

Summary: Development of advanced high-voltage electrolytes is crucial for high-energy-density lithium metal batteries. Weakly solvating electrolytes can produce unique anion-driven interphasial chemistry by altering the solvent's solvating power. A new-type weakly solvating electrolyte regulated by the anion was successfully used to achieve stable cycling of dimethoxyethane at 4.6 V. The electrolyte's solvation structure and the degree of dissociation of salts were found to affect the electrochemical performance of the lithium metal batteries.

Summary: Doping a catalyst can improve the hydrogen reaction kinetics of MgH2, but the hydrogen desorption behaviors in different MgH2-catalyst systems are complicated. A carbon-encapsulated nickel (Ni@C) core-shell catalyst is synthesized to enhance the hydrogen storage properties of MgH2. The study provides new insights into the hydrogen desorption behaviors and reveals the short-range nanoreaction effect in the MgH2-catalyst system.

Summary: The highly complex crystal structure of stoichiometric Mg-5(en)(6)(BH4)(10) was determined using single crystal synchrotron X-ray diffraction and confirmed by neutron powder diffraction on isotopically substituted Mg(en)(1.2)((BD4)-B-11)(2). The role of amorphous Mg(BH4)(2) in the reactivity of the Mg(BH4)(2)-en system was emphasized, and a previously overlooked phase, Mg(en)(2)(BH4)(2), was characterized.

Crystal structure and hydrogen storage properties of AB-type TiZrNbCrFeNi high-entropy alloy

Gaspar Andrade, Guilherme Zepon, Kaveh Edalati, Abbas Mohammadi, Zhongliang Ma, Hai-Wen Li, Ricardo Floriano

Summary: The crystal structure and hydrogen storage properties of a new equiatomic TiZrNbCrFeNi high-entropy alloy (HEA) were investigated. The alloy exhibited an AB-type configuration, selected through thermodynamic calculations and showed the ability to absorb 1.5 wt% of hydrogen at room temperature without activation. Cyclical testing revealed changes in the fractions of two C14 Laves phases, with one phase having higher reactivity towards hydrogen. The alloy exhibited a single C14 Laves phase after dehydrogenation at 473 K, and microstructural analysis showed excellent homogeneity and element distribution.

Impact of severe plastic deformation on kinetics and thermodynamics of hydrogen storage in magnesium and its alloys

Kaveh Edalati, Etsuo Akiba, Walter J. Botta, Yuri Estrin, Ricardo Floriano, Daniel Fruchart, Thierry Grosdidier, Zenji Horita, Jacques Huot, Hai-Wen Li, Huai-Jun Lin, Adam Revesz, Michael J. Zehetbauer

Summary: Magnesium and its alloys are extensively studied for solid-state hydrogen storage, but there are challenges in the kinetics and thermodynamics of hydrogenation and dehydrogenation. Severe plastic deformation methods have been utilized to improve the activation, air resistance, and kinetics of Mg-based hydrogen storage materials by introducing ultrafine/nanoscale grains and crystal lattice defects. These deformed materials, particularly with alloying additives or second-phase nanoparticles, exhibit fast hydrogen absorption/desorption kinetics and good cycling stability. The study also highlights the application of severe plastic deformation methods in hydrogen binding-energy engineering and the synthesis of new magnesium alloys for reversible low/room-temperature hydrogen storage.

Liquid Channels Built-In Solid Magnesium Hydrides for Boosting Hydrogen Sorption

Zhi-Kang Qin, Li-Qing He, Xiao-Li Ding, Ting-Zhi Si, Ping Cui, Hai-Wen Li, Yong-Tao Li

Summary: Building liquid channels in magnesium hydride by introducing lithium borohydride ion conductors improves its low-temperature hydrogen sorption. For example, 5 wt% LiBH4-doped MgH2 can release about 7.1 wt.% H-2 within 40 min at 300 degrees C, while pure MgH2 only desorbs less than 0.7 wt.% H-2. Additionally, the LiBH4-doped MgH2 exhibits faster desorption kinetics with more than 10 times enhancement compared to pure MgH2, and maintains a stable cyclic performance even after six absorption and desorption cycles. This approach provides insights for promoting hydrogen absorption and desorption of other metal hydrides.

Junrui Zhang, Haiwen Li, Xuezhang Xiao, Liuzhang Ouyang

Summary: Metal borohydrides have high theoretical hydrogen production/storage densities and offer efficient real-time hydrogen supply for electronics. However, their practical applications are limited. Strategies to overcome these limitations, such as optimizing the boron/hydrogen source and reducing agent, are summarized in this review. Ouyang developed a practical and low-cost method for regenerating MBH4 by ball milling, which has the potential to decrease the synthesis cost and increase the reversibility of metal borohydrides.
