Abstract: The increasing demand for high-energy Li-ion batteries for theelectrification of personal transportation may lead to uncertainty inthe global supply of raw materials (Co and Ni). Here we propose a novelMn-rich composition, which has a quasi-ordered structure with previouslyunobserved two intermixed cation-ordering sequences. The partiallyordered structure stabilizes the delithiated cathode at a high cut-off voltage,offering strain-free characteristics, with structural variations along boththe a and c axes limited to approximately 1%. Consequently, the cathode canoperate at 4.6 V while delivering a reversible capacity comparable to that ofNi-rich Li(Ni0.8Co 0.1Mn0.1)O2. Moreover, a high capacity is maintained duringlong-term and high-voltage cycling in full cells with exceptional thermalsafety. The high-performance Mn-rich layered cathodes characterized byquasi-ordered crystal structure can potentially relieve supply uncertaintyresulting from the rising demand for Ni in the battery industry andenvironmental concerns associated with the extraction of Ni from its ores.
