Toward Practical Li-Ion Cells With Li/Mn-Rich Layered Oxide Cathodes: A Techno-Economic Perspective on Material and Cell Design.

ABSTRACT: Li/Mn-rich layered oxide (LMR) cathode active materials offer a pathway towards high specific energy and low-cost Li ion batteries (LIBs) due to their high practical specific discharge capacity (>250 mAh g^-1) at moderate discharge voltages (≈3.5 V). However, oxygen redox requires electrochemical activation at high cathode potentials (> 4.5 V vs Li|Li⁺), resulting in bulk degradation and surface reactivity. This perspective first summarizes the literature-known efforts to elucidate the oxygen redox mechanism and then proposes strategies for systematic R&D of LMR, supported with techno-economic analysis. Initially, bulk degradation should be addressed via compositional tuning and crystal modification. Subsequently, the microstructure, interphase, and electrolyte should
