Lithium ion batteries are today’s state-of-the-art energy storage technologies. Due to high volumetric and energy densities, they have become the industry standard for portable applications such as consumer electronics and hybrid vehicles. However, lithium ion batteries also have large capital costs, which make them prohibitively expensive for grid-based energy storage. Therefore, there is a clear need for new innovative energy storage systems which are able to meet the required performance standards as well as the necessary economic benchmarks that make them commercially viable. Compared to lithium ion batteries, magnesium and sodium batteries provide a very attractive low-cost alternative. However, establishing suitable electrode chemistries for non-lithium batteries remains a crucial challenge. In this talk, I will highlight our group’s recent work on identifying suitable electrode materials for Sodium and Magnesium batteries using advanced computational techniques. Our analysis establishes the electrochemical performance of these materials as well as their viability as electrodes in next generation, low cost batteries.
