Here, we propose an ‘in situ LiF nanodecoration’ approach to address this issue. By uniform dispersion of ultrafine LiF nanoparticles in amorphous Li2B12H12 matrix that is in situ formed via a solid-state reaction, the resulting composite as electrolyte exhibits favorable Li-ion conductivity (5 × 10−4 S cm−1) with low electronic conductivity (9 × 10−10 S cm−1) at 75 °C. More importantly, this composite electrolyte shows superior electrode compatibility by forming stable electrolyte/electrode interfaces, as demonstrated by high Li dendrite suppression capability (critical current density: 3.6 mA cm−2) and small interfacial resistance (area specific resistance after 10 cycles: 746 Ω cm2) at 75 °C, which further enables the stable cycling of Li–LiFePO4 all-solid-state batteries. This work paves a way for using in- situ nanodecoration chemistry for the design of safe and high efficiency all-solid-state batteries..

Central to this discussion is the use of hydrogen, as a clean, efficient energy vector for energy storage. This review, by experts of Task 32, “Hydrogen-based Energy Storage” of the International Energy Agency, Hydrogen TCP, reports on the development over the last 6 years of hydrogen storage materials, methods and techniques, including electrochemical and thermal storage systems. An overview is given on the background to the various methods, the current state of development and the future prospects. The following areas are covered; porous materials, liquid hydrogen carriers, complex hydrides, intermetallic hydrides, electrochemical storage of energy, thermal energy storage, hydrogen energy systems and an outlook is presented for future prospects and research on hydrogen-based energy storage..

Mingwei Hu, Jin Huang, Qizhong Li, Rong Tu, Song Zhang, Meijun Yang, Haiwen Li, Takashi Goto, Lianmeng Zhang, Self-supported MoSx/V2O3 heterostructures as efficient hybrid catalysts for hydrogen evolution reaction, Journal of Alloys and Compounds, 10.1016/j.jallcom.2020.154262, 827, 2020.06, Earth-abundant and low-cost hydrogen evolution reaction (HER) electrocatalysts represent a future direction for achieving sustainable hydrogen energy production. Low-cost amorphous molybdenum sulfides (MoSx), with their highly active HER activity, have emerged as outstanding catalysts for electrochemical hydrogen production. Herein, we report the development of a synergetic amorphous MoSx hybrid catalysts on V2O3 with optimized HER activity of MoSx. Our synthetic and structural characterization shows that MoSx distributes on V2O3 uniformly. HER-inert V2O3 provides a highly electrochemically active surface area for HER and promotes electron transport. The obtained hybrid MoSx/V2O3/CC catalyst exhibits a low overpotential of 146 mV at 10 mA cm−2 toward HER under acidic conditions, which is comparable with the current advanced catalysts, and high stability with no significant changes over 10 h of electrolysis. The density functional theory calculations also demonstrate that the interface of V2O3 and MoSx helps to improve the conductivity..
4. Zhijie Gao, Qingwu Meng, Ying Zhang, Faliang Zhang, Yongchun Luo, Hai Wen Li, An alternative for the anode materials of nickel metal hydride batteries
an AB3-type La0.6Gd0.2Mg0.2Ni2.6Co0.3Al0.1hydrogen storage alloy, Dalton Transactions, 10.1039/d0dt00774a, 49, 19, 6312-6320, 2020.05, In order to satisfy the demand for the cyclic stability of commercial Ni-MH anodes, a PuNi3-type La0.6Gd0.2Mg0.2Ni2.6Co0.3Al0.1alloy with excellent overall electrochemical properties was prepared by annealing the as-cast alloy sample at different temperatures for a week. The alloy had the highest PuNi3-type content of 86.9 wt% (1073 K), which offered a capacity retention of 69.6% after 100 cycles. However, 23.7 wt% PuNi3type phase of the alloy constantly converted into the Ce2Ni7type phase within a temperature increase of 50 °C, which improved the capacity retention by 12.1% under the same discharge capacity. We found that the addition of Gd did not change the stacked [LaMgNi4]/[LaNi5] superlattice and it maintained the structural stability of the crystal as well as its anti-corrosion, which is also a key factor to improve cyclic stability. These findings imply that alloys with both PuNi3-type and Ce2Ni7-type multiphase structures can be considered as a new choice for hydrogen storage..

Zhongliang Ma, Jiangchuan Liu, Yunfeng Zhu, Yingyan Zhao, Huaijun Lin, Yao Zhang, Haiwen Li, Jiguang Zhang, Yana Liu, Wentian Gao, Shanshan Li, Liquan Li, Crystal-facet-dependent catalysis of anatase TiO2 on hydrogen storage of MgH2, Journal of Alloys and Compounds, 10.1016/j.jallcom.2019.153553, 822, 2020.05, Various catalysts are developed to enhance the hydrogen storage performances of magnesium based hydride. In particular, the morphology of catalysts governs their surface energy and chemical interactions with Mg and hydrogen, which makes it possible to adjust the hydrogen reaction kinetics of MgH2 through morphological design of the catalysts. Here, we report a novel crystal-facet-dependent catalysis of TiO2 on hydrogen storage of MgH2. Different facets dominant anatase TiO2 (named TFx, x = 0, 10, 30, 50, 70 and 80) are prepared via a hydrothermal synthesis approach and then doped into MgH2 via ball milling. Results show anatase TiO2 with high percentage {001} facets has much better catalytic effect than that with low percentage {001} facets. The MgH2-TF70 exhibits the best hydrogen sorption kinetics, showing apparent activation energy for dehydriding of only 76.1 ± 1.6 kJ mol−1. The present study constructs a new bridge between the catalytic effect of catalysts with different crystal facets and the hydrogen storage property of MgH2..
6. Parisa Edalati, Ricardo Floriano, Abbas Mohammadi, Yongtao Li, Guilherme Zepon, Hai Wen Li, Kaveh Edalati, Reversible room temperature hydrogen storage in high-entropy alloy TiZrCrMnFeNi, Scripta Materialia, 10.1016/j.scriptamat.2019.12.009, 178, 387-390, 2020.03, Despite potential of hydride-forming alloys for hydrogen storage, there have been few alloys which can reversibly store hydrogen without heating or activation treatment. In this study, a high-entropy alloy is designed for room temperature hydrogen storage based on three criteria: total valence electron concentration (VEC) of 6.4, single-phase thermodynamic stability (examined by CALPHAD calculations) and AB2H3 hydride formation (A: hydride-forming elements, B: elements without affinity to hydrogen, H: hydrogen). The designated alloy, TiZrCrMnFeNi containing 95 wt% C14 Laves phase, absorbs and desorbs 1.7 wt% of hydrogen (hydrogen-to-metal ratio: 1) at room temperature with a fast kinetics and without activation treatment..
7. Zhaohuai Li, Cheng Zhou, Junhui Hua, Xufeng Hong, Congli Sun, Hai Wen Li, Xu Xu, Liqiang Mai, Engineering Oxygen Vacancies in a Polysulfide-Blocking Layer with Enhanced Catalytic Ability, Advanced Materials, 10.1002/adma.201907444, 32, 10, 2020.01, The practical application of the lithium–sulfur (Li–S) battery is seriously restricted by its shuttle effect, low conductivity, and low sulfur loading. Herein, first-principles calculations are conducted to verify that the introduction of oxygen vacancies in TiO2 not only enhances polysulfide adsorption but also greatly improves the catalytic ability and both the ion and electron conductivities. A commercial polypropylene (PP) separator decorated with TiO2 nanosheets with oxygen vacancies (OVs-TiO2@PP) is fabricated as a strong polysulfide barrier for the Li–S battery. The thickness of the OVs-TiO2 modification layer is only 500 nm with a low areal mass of around 0.12 mg cm−2, which enhances the fast lithium-ion penetration and the high energy density of the whole cell. As a result, the cell with the OVs-TiO2@PP separator exhibits a stable electrochemical behavior at 2.0 C over 500 cycles, even under a high sulfur loading of 7.1 mg cm−2, and an areal capacity of 5.83 mAh cm−2 remains after 100 cycles. The proposed strategy of engineering oxygen vacancies is expected to have wide applications in Li–S batteries..
8. Kai Chao Pu, Xin Zhang, Xiao Lei Qu, Jian Jiang Hu, Hai Wen Li, Ming Xia Gao, Hong Ge Pan, Yong Feng Liu, Recently developed strategies to restrain dendrite growth of Li metal anodes for rechargeable batteries, Rare Metals, 10.1007/s12598-020-01432-2, 2020.01, Lithium metal has been regarded as one of the most promising anode materials for high-energy-density batteries due to its extremely high theoretical gravimetric capacity of 3860 mAh·g−1 along with its low electrochemical potential of − 3.04 V. Unfortunately, uncontrollable Li dendrite growth and repetitive destruction/formation of the solid electrolyte interphase layer lead to poor safety and low Coulombic efficiencies (CEs) for long-term utilization, which largely restricts the practical applications of lithium metal anode. In this review, we comprehensively summarized important progresses achieved to date in suppressing Li dendrite growth. Strategies for protection of Li metal anodes include designing porous structured hosts, fabricating artificial solid electrolyte interface (SEI) layers, introducing electrolyte additives, using solid-state electrolytes and applying external fields. The protection of Li metal anodes can be achieved by regulating the stripping and deposition behaviours of Li ions. Finally, the challenges remaining for lithium metal battery systems and future perspectives for Li metal anodes in practical applications are outlined, which are expected to shed light on future research in this field..
9. Marcelo Orpinelli de Marco, Yongtao Li, Hai Wen Li, Kaveh Edalati, Ricardo Floriano, Mechanical Synthesis and Hydrogen Storage Characterization of MgVCr and MgVTiCrFe High-Entropy Alloy, Advanced Engineering Materials, 10.1002/adem.201901079, 2019.11, Body-centered cubic (BCC) and high-entropy alloys are being investigated as potential hydrogen storage materials due to their ability to absorb high amounts of hydrogen at moderate temperatures. Herein, the synthesis and hydrogen storage behavior of new MgVCr BCC and MgTiVCrFe high-entropy alloys are studied. The alloys are initially synthesized by mechanical alloying via high-energy ball milling (HEBM) under hydrogen atmosphere followed by high-pressure torsion (HPT) processing to improve activation. X-ray diffraction (XRD) in combination with transmission electron microscopy (TEM) shows a very refined nanostructure in both samples with the presence of a BCC solid solution phase for MgVCr, whereas the crystalline and amorphous phases coexist in MgTiVCrFe. The MgVCr alloy exhibits fast kinetics but with a low reversible hydrogen storage capacity (up to 0.9 wt%), whereas MgTiVCrFe shows low affinity to absorb hydrogen. Moreover, MgTiVCrFe demonstrates a partial decomposition from the initial structure by hydrogen storage cycling, whereas MgVcr exhibits reasonable stability..
10. Zhijie Gao, Yuhong Geng, Zhen Lin, Yongxiang Wei, Yongchun Luo, Hai Wen Li, Synergistic effects of Gd and Co on the phase evolution mechanism and electrochemical performances of Ce2Ni7-type La-Mg-Ni-based alloys, Dalton Transactions, 10.1039/c9dt03944a, 49, 1, 156-163, 2019.11, The influences of Gd and Co co-substitution for La and Ni on phase structures, and electrochemical properties of La0.83-xGdxMg0.17Ni3.35-2xCo2xAl0.15 (x = 0-0.83) alloys were investigated. All the alloys contained A2B7-type (Ce2Ni7- and Gd2Co7-type) phase, Pr5Co19-type phase, PuNi3-type phase and CaCu5-type phase. The partial replacement of Gd and Co for La and Ni increased the phase abundance of the Ce2Ni7-type superstructure and decreased cell volumes, which contributed to a better hydrogen absorption capacity, cyclic stability and HRD. Compared to those of single Gd- or Co-substitutions, the synergistic effects of Gd and Co on the overall electrochemical properties of alloys were significant. Such a superior overall electrochemical performance may result from appropriate cell volumes and anti-pulverization abilities..

Fan, Wan Jiang, Lianmeng Zhang, MoS2 coating on CoSx-embedded nitrogen-doped-carbon-nanosheets grown on carbon cloth for energy conversion, Journal of Alloys and Compounds, 10.1016/j.jallcom.2019.07.298, 806, 1276-1284, 2019.10, Designing low-cost and highly efficient electrocatalysts has become a critical aspect to achieve sustainable energy production. Herein, we report the preparation strategy of MoS2 on Co-oxide nanoparticles embedded nitrogen-doped carbon nanosheets (Co-NC) those derived by ZIF-L anchored on a carbon cloth as an electrode for hydrogen evolution reaction (HER). The hybrid electrode denoted as MoS2/Co-NC/CC was synthesized in sequence of the growth of the leaf-like zeolitic imidazolate framework (Co-ZIF-L) on a carbon cloth (CC), the carbonization of the Co-ZIF-L and deposition of MoS2 by metal organic chemical deposition (MOCVD). The hierarchical porous catalyst presented remarkable electrochemical activity towards the HER in acidic solution, exhibiting great stability and fast kinetics with a small Tafel slope of 51 mV dec−1. Moreover, to produce a current density of 10 mA cm−210), MoS2/Co-NC/CC required a low overpotential of 111 mV, which is comparable with Pt..

N -heterocycles: Boosting the activity via a new hydrogen transfer path and controlling the stereoselectivity, Chemical Science, 10.1039/c9sc04365a, 10, 45, 10459-10465, 2019.10, Hydrogenation of N-heterocycles is of great significance for their wide range of applications such as building blocks in drug and agrochemical syntheses and liquid organic hydrogen carriers (LOHCs). Pursuing a better hydrogenation performance and stereoselectivity, we successfully developed a rare earth hydride supported ruthenium catalyst Ru/YH3; for the hydrogenation of N-heterocycles, especially N-ethylcarbazole (NEC), the most promising LOHC. Full hydrogenation of NEC on Ru/YH3 can be achieved at 363 K and 1 MPa hydrogen pressure, which is currently the lowest compared to previous reported catalysts. Furthermore, Ru/YH3 shows the highest turnover number, namely the highest catalytic activity among the existing catalysts for hydrogenation of NEC. Most importantly, Ru/YH3 shows remarkable stereoselectivity for all-cis products, which is very favorable for the subsequent dehydrogenation. The excellent performance of Ru/YH3 originates from the new hydrogen transfer path from H2 to NEC via YH3. Ru/LaH3 and Ru/GdH3 also reveal good activity for hydrogenation of NEC and Ru/YH3 also possesses good activity for hydrogenation of 2-methylindole, indicating that the use of rare earth hydride supported catalysts is a highly effective strategy for developing better hydrogenation catalysts for N-heterocycles..

A review, Inorganics, 10.3390/inorganics6010010, 6, 1, 2018.03, NaBH4 hydrolysis can generate pure hydrogen on demand at room temperature, but suffers from the difficult regeneration for practical application. In this work, we overview the state-of-the-art progress on the regeneration of NaBH4 from anhydrous or hydrated NaBO2 that is a byproduct of NaBH4 hydrolysis. The anhydrous NaBO2 can be regenerated effectively by MgH2, whereas the production of MgH2 from Mg requires high temperature to overcome the sluggish hydrogenation kinetics. Compared to that of anhydrous NaBO2, using the direct hydrolysis byproduct of hydrated NaBO2 as the starting material for regeneration exhibits significant advantages, i.e., omission of the high-temperature drying process to produce anhydrous NaBO2 and the water included can react with chemicals like Mg or Mg2Si to provide hydrogen. It is worth emphasizing that NaBH4 could be regenerated by an energy efficient method and a large-scale regeneration system may become possible in the near future..
