Summary: This study investigates the Mg substitution of Ni-rich LiNi1-x-yMnxCoyO2 (NMC) layered oxides and demonstrates a linear correlation between cycle life and attainable gravimetric capacities, which are influenced by the degree of Mg substitution and the amount of cycled Li+ ions. To achieve a higher energy density, a lower Mg content and higher Ni content should be considered.

Summary: In this study, a method is proposed to mitigate the formation of micro-cracks in LiNiO2-based cathode materials in lithium-ion batteries by controlling the structure of transition metal oxides and doping with Ti. It is found that LiNiTiO2 exhibits lower lattice strain during charging compared to LiNiO2, indicating reduced mechanical failures. Ti doping induces a uniform bond network that connects the NiO6 octahedral network, and the difference in Li-O bond populations between the two materials is attributed to the chemical stiffness. This study provides insights into the mechanism of the Ti-doping effect and offers a strategy to enhance the durability of high-energy-density LIBs.

Summary: Anionic redox in Li-ion cathodes offers increased energy density but comes with drawbacks such as voltage hysteresis. This study investigates the origin of voltage hysteresis by designing a Li-rich cation-disordered rock-salt compound and reveals a non-equilibrium redox pathway responsible for voltage hysteresis. The charge transfer involving structural distortion between O and Fe states is found to be the cause of voltage hysteresis.

Summary: Understanding the anionic redox behavior with respect to metal-ligand interactions in Li-rich oxide cathodes is crucial for developing high-capacity battery materials. By analyzing the orbital combinations of transition metals and oxygen in LROs, it was found that a pi-type oxygen redox mode can be achieved at low voltages, expanding the fundamental theories of anionic redox and providing a new design route for high-capacity cathode materials. The interaction between oxygen and central Rh in Li2RhO3 demonstrates high reactivity in the occupied anti-bonding state, showing a novel low-voltage oxygen redox mechanism.
