Integrated Li- and Mn-rich layered cathodes yLi2MnO3∙(1-y)LiMO2 (M = Mn, Co, Ni) have shown their ability to deliver specific capacities close 300 mAh g−1, but significant drawbacks are capacity fading voltage decay during cycling. In this study, new stoichiometric high-voltage Li-rich oxides with y 0.0, 0.3, 0.5 synthesized in identical conditions using a sol–gel method. These compositions were analyzed determine optimal configuration understand extraordinary behavior. Their nanostructural properties investigated XRD Raman spectroscopy, while the morphology grain-size distribution of samples characterized by BET, SEM HRTEM analyses. The electrochemical performances integrated compounds evaluated through galvanostatic cycling impedance spectroscopy. best cathode material 0.5Li2MnO3∙0.5LiNi1/3Co1/3Mn1/3O2 had retention 83.6% after 100 cycles potential range 2.0–4.8 V vs. Li+/Li.

Abstract Exhibiting exceptional energy density and capacity, lithium‐rich manganese‐based layered oxide (LLOs) cathode materials have garnered considerable attention are emerging as strong contenders for future lithium‐ion battery systems. However, the manner in which they employed practice is hindered by several challenges, such voltage fading, exhibiting a low initial coulombic efficiency, suboptimal cycling stability, mainly attributed to oxygen depletion phase transformation phenomena. The current review primarily centers on recent progress addressing these issues through surface interfacial modification techniques, including doping, coating, vacancy engineering. Other strategies, spinel engineering hybrid coating layers, also discussed potential solutions enhance electrochemical performance, capacity retention. Additionally, exploration advancements electrolyte design aimed at stabilizing LLOs/electrolyte interface, reducing side reactions, enabling development of stable solid interphase (CEI). concludes highlighting ongoing particularly improving long‐term proposes prospective research directions further unlocking LLOs practical applications.
