Development of High-Performance Manganese-Rich Layered Oxide Cathodes for Lithium-Ion Batteries

Abstract

The transition to sustainable energy storage systems necessitates the development of cathode materials that combine high performance with resource earth-abundance. Manganese-rich layered oxides have emerged as promising candidates, offering high specific capacities and favorable sustainability. This presentation will discuss work ongoing at Argonne National Laboratory related to the study of lithium-ion cathodes. In this work, we report the design and electrochemical evaluation of Mn-rich layered oxide compositions tailored. Through systematic tuning of transition metal content and lithium excess, alongside modifications, we achieve stable cycling performance in full-cell configurations. Selected compositions deliver high-capacity retention at practical loadings and voltages, demonstrating their suitability for EVs and grid-scale applications. Techno-economic analysis further supports the commercial potential of these materials by projecting competitiveness with commercial cathode materials. These findings underscore the viability of Mn-based layered oxides as next-generation cathodes that address both performance and supply chain resilience.
