Abstract/OtherAbstract:
The lack of a high capacity hydrogen storage material is a major barrier to the implementation of the hydrogen economy. To accelerate discovery of such materials, we have developed a high-throughput workflow for screening of hydrogen storage materials in which candidate materials are synthesized and characterized via highly parallel ball mills and volumetric gas sorption instruments, respectively. The workflow was used to identify mixed imides with significantly enhanced absorption rates relative to Li(2)Mg(NH)(2). The most promising material, 2LiNH(2):MgH(2) + 5 atom % LiBH(4) + 0.5 atom % La, exhibits the best balance of absorption rate, capacity, and cycle-life, absorbing >4 wt % H(2) in 1 h at 120 °C after 11 absorption-desorption cycles.
