Lithium-ion batteries (LIBs) are crucial in renewable energy storage and are the fastest-growing technology in this field, with cathode materials being vital in optimizing energy density. Among this class of materials, lithium- and manganese-rich (LMR) layered oxides with high capacity and low cost are promising cathodes for the next-generation Li-ion batteries. However, substantial voltage decay during cycling is still an obstacle to their practical deployment. Recently, researchers from City University of Hong Kong (CityU), Northwestern University, and the Argonne National Laboratory in the US jointly reported a cobalt-free LMR Li-ion battery cathode with negligible voltage decay, which opens an avenue to developing next-generation high-energy cathode materials.
