Abstract: 3D porous carbon-coated Li3 N nanofibers are successfully fabricated via the electrospinning technique. The as-prepared nanofibers exhibit a highly improved hydrogen-sorption performance in terms of both thermodynamics and kinetics. More interestingly, a stable regeneration can be achieved due to the unique structure of the nanofibers, over 10 cycles of H2 sorption at a temperature as low as 250 °C.

Abstract: The monoammoniate of lithium amidoborane, Li(NH(3))NH(2)BH(3), was synthesized by treatment of LiNH(2)BH(3) with ammonia at room temperature. This compound exists in the amorphous state at room temperature, but at -20 degrees C crystallizes in the orthorhombic space group Pbca with lattice parameters of a = 9.711(4), b = 8.7027(5), c = 7.1999(1) A, and V = 608.51 A(3). The thermal decomposition behavior of this compound under argon and under ammonia was investigated. Through a series of experiments we have demonstrated that Li(NH(3))NH(2)BH(3) is able to absorb/desorb ammonia reversibly at room temperature. In the temperature range of 40-70 degrees C, this compound showed favorable dehydrogenation characteristics. Specifically, under ammonia this material was able to release 3.0 equiv hydrogen (11.18 wt %) rapidly at 60 degrees C, which represents a significant advantage over LiNH(2)BH(3). It has been found that the formation of the coordination bond between ammonia and Li(+) in LiNH(2)BH(3) plays a crucial role in promoting the combination of hydridic B-H bonds and protic N-H bonds, leading to dehydrogenation at low temperature.

Abstract: Requiring high temperature for hydrogen storage is the main feature impeding practical application of light metal hydrides. Herein, to lift the restrictions associated with traditional electric heating, light is used as an alternative energy input, and a light‐mediated catalytic strategy coupling photothermal and catalytic effects is proposed. With NaAlH 4 as the initial target material, TiO 2 nanoparticles uniformly distribute on carbon nanosheets (TiO 2 @C), which couples the catalytic effect of TiO 2 and photothermal property of C, is constructed to drive reversible hydrogen storage in NaAlH 4 under light irradiation. Under the catalysis of TiO 2 @C, complete hydrogen release from NaAlH 4 is achieved within 7 min under a light intensity of 10 sun. Furthermore, owing to the stable catalytic and photothermal effect of TiO 2 @C, NaAlH 4 delivers a reversible capacity of 4 wt% after 10 cycles with a capacity retention of 85% under light irradiation only. The proposed strategy is also applicable to other light metal hydrides such as LiAlH 4 and MgH 2 , validating its universality. The concept of light‐driven hydrogen storage provides an alternative approach to electric heating, and the light‐mediated catalytic strategy proposed herein paves the way to the design of reversible high‐density hydrogen storage systems that do not rely on artificial energy.

Abstract: Lithium (Li) metal is regarded as one of the most promising anode candidates for future high energy density lithium batteries. The practical application of Li‐metal anodes, however, is hindered by the uncontrollable growth of dendrites resulting from both huge volume change and unstable solid‐electrolyte interfaces upon cycling. Herein, we propose a novel “house strategy” that utilizes the 3D NiO nanosheets decorated nickel foam as the frame to confine Li metal and the inorganic [LiNBH] n chains with high Li ion conductivity as the artificial protective proof to establish a stable dendrite‐free Li metal anode. Benefiting from the synergistic effect of the 3D NiO/Ni foam in lowering the local current density and accommodating the huge volume change of Li metal and the [LiNBH] n protective layer in facilitating uniform Li + diffusion and regulating Li deposition beneath this layer, the LiNBH‐Li@Ni electrode presents an excellent long‐term cycling lifespan of over 800 h at both 1 and 3 mA cm −2 with a high areal capacity of 5 mAh cm −2 in symmetric cells. Upon coupling this anode with LiFePO 4 cathode, the thus‐assembled full cells deliver an ultrahigh reversible capacity of 127.4 mAh g −1 at 1 C after 200 cycles.

Abstract: Monodisperse MgH2 nanoparticles with homogeneous distribution and a high loading percent are developed through hydrogenation-induced self-assembly under the structure-directing role of graphene. Graphene acts not only as a structural support, but also as a space barrier to prevent the growth of MgH2 nanoparticles and as a thermally conductive pathway, leading to outstanding performance.

Abstract: The limited energy density, lifespan, and high cost of lithium-ion batteries (LIBs) drive the development of new-type affordable batteries. As a green and cheap alternative, dual-graphite batteries (DGBs) have received much attention recently however, they have been criticized for low capacity, electrode durability, and “real” energy density. Here, we designed hybrid LiFePO 4 (LFP)/graphite electrodes that operate with a staged deintercalation/intercalation of the Li + and PF 6 − mechanism. Introducing graphite into LFP not only accelerates the electrochemical performance of LFP but also unlocks the electrolyte role by providing active sites for PF 6 − intercalation. This work provides insights to optimize the current LIB technology by full utilization of in idual components, including electrolyte.

Abstract: LiBH 4 /Al mixtures with various mol ratios were prepared by ball milling. The hydrogen storage properties of the mixtures were evaluated by differential scanning calorimetry/thermogravimetry analyses coupled with mass spectrometry measurements. The phase compositions and chemical state of elements for the LiBH 4 /Al mixtures before and after hydrogen desorption and absorption reactions were assessed via powder x-ray diffraction, infrared spectroscopy, and x-ray photoelectron spectroscopy. Dehydrogenation results revealed that LiBH 4 could react with Al to form AlB 2 and AlLi compounds with a two-step decomposition, resulting in improved dehydrogenation. The rehydrogenation experiments were investigated at 600 °C with various H 2 pressure. It was found that intermediate hydride was formed firstly at a low H 2 pressure of 30 atm, while LiBH 4 could be reformed completely after increasing the pressure to 100 atm. Absorption/desorption cycle results showed that the dehydrogenation temperature increased and the hydrogen capacity degraded with the increase of cycle numbers.

Abstract: The lack of safe and efficient hydrogen storage is a major bottleneck for large‐scale application of hydrogen energy. Reversible hydrogen storage of light‐weight metal hydrides with high theoretical gravimetric and volumetric hydrogen density is one ideal solution but requires extremely high operating temperature with large energy input. Herein, taking MgH 2 as an ex le, a concept is demonstrated to achieve solar‐driven reversible hydrogen storage of metal hydrides via coupling the photothermal effect and catalytic role of Cu nanoparticles uniformly distributed on the surface of MXene nanosheets (Cu@MXene). The photothermal effect of Cu@MXene, coupled with the “heat isolator” role of MgH 2 indued by its poor thermal conductivity, effectively elevates the temperature of MgH 2 upon solar irradiation. The “hydrogen pump” effect of Ti and TiH x species that are in situ formed on the surface of MXene from the reduction of MgH 2 , on the other hand, plays a catalytic role in effectively alleviating the kinetic barrier and hence decreasing the operating temperature required for reversible hydrogen adsorption and desorption of MgH 2 . Based on the combination of photothermal and catalytic effect of Cu@MXene, a reversible hydrogen storage capacity of 5.9 wt% is achieved for MgH 2 after 30 cycles using solar irradiation as the only energy source.
