Kurzfassung:
The predicted growth in electrification of the grid-storage and transportation sectors has seemingly left the research community a significant responsibility in developing a more robust portfolio of materials solutions. Specifically, it has become clear that beyond simply meeting/exceeding the current technical requirements, new technologies would do well to align with the goals of sustainable development in supporting market growth. Current state-of-the-art, Li-ion cathodes, based heavily in Ni, will continue to play an important role. However, alternatives to these chemistries will be critical in diversifying supply chains and expanding the available portfolio of electrode materials towards a more sustainable future. Among the potential candidates for next-generation cathodes are Lithium- and Manganese-rich oxides. These oxides remain attractive because of their intrinsically high, specific capacities/energies and the economic benefits they offer through earth-abundant, Mn-rich ( 〉 50%) compositions. This presentation will discuss research and development efforts at Argonne National Laboratory aimed at advancing cathode materials that are rich in manganese and have the potential to be cost competitive for electric vehicle applications and beyond. Research efforts into mitigation of issues related to several identified critical barriers , such as impedance, will be discussed.
