We discuss the key challenge of developing functional Mg battery cathode, and propose to use NEB algorithm in high-throughput calculations to screen for materials with good Mg\" diffusivity. However, though NEB algorithm performs quite well on individual systems, due to its very long run-time, it is difficult to be scaled up in high-throughput applications. Therefore, new algorithms are developed and implanted, and 17 potential Mg cathode materials are selected by the new high-throughput system. The main contributions of this thesis are: (1) developed new algorithms for NEB calculations in highthroughput environments; (2) implemented a functional software system for conducting high-throughput migration energy calculations, which can be further applied in other research areas like Ca batteries, Zn batteries, solid state conductors, etc.; (3) proposed new Mg cathode materials.","abstract_html":"In this thesis, we demonstrate the results and progress of developing a high-throughput migration energy calculation machinery and applying it in search for Mg battery cathode materials.
