(Invited) Recent Developments in Lithium-Manganese-Oxide Electrochemistry

There has been a concerted effort over the past several years to design and develop manganese-rich lithium-metal-oxide cathodes for the lithium-ion battery industry. The prime motivation for this endeavor is to identify more cost effective and high energy electrode materials that can compete with today's Ni-rich (NMC) and LiFePO4 (LFP) systems. This presentation will cover recent developments at Argonne National Laboratory, highlighting the progress made in developing, characterizing and understanding disordered rocksalt- and lithiated-spinel electrode materials with a high manganese content, with a particular focus on cobalt-free systems.
