Bulk Fatigue Induced by Surface Reconstruction in Layered Ni-Rich Oxide Cathodes for Liion Batteries [PDF]

, 2020
Ni-rich layered cathode materials are among the most promising candidates for high energy density Li-ion batteries. However, the low cobalt containing materials suffer from rapid degradation, the underlying mechanism of which is still poorly understood ...

Beyond Doping and Coating: Prospective Strategies for Stable High-Capacity Layered Ni-Rich Cathodes

, 2020
This Perspective discusses the prospective strategies for overcoming the stability and capacity trade-off associated with increased Ni content in layered Ni-rich Li­[NixCoyMnz]­O2 (NCM) and Li­[NixCoyAlz]­O2 (NCA) cathodes.

Enhancing surface‐to‐bulk stability of layered Co‐free Ni‐rich cathodes for long‐life Li‐ion batteries

Battery Energy, 2023
Layered Co‐free Ni‐rich cathodes are the most cost‐effective for high‐energy‐density Li‐ion batteries (LIBs), yet the structural instability and interfacial side reactions seriously hamper their commercial applications versus the Co‐contained counterpart.

Enhancing cyclic and in-air stability of Ni-Rich cathodes through perovskite oxide surface coating [PDF]

, 2022
Ni-rich layered oxides, such as LiNi0.8Co0.1Mn0.1O2 (NCM811), are promising cathode materials for high-energy lithium-ion batteries. However, the relatively high reactivity of Ni in NCM811 cathodes results in severe capacity fading originating from the ...

The Role of Ni and Co in Suppressing O‐Loss in Li‐Rich Layered Cathodes [PDF]

, 2020
Lithium‐rich transition metal cathodes can deliver higher capacities than stoichiometric materials by exploiting redox reactions on oxygen. However, oxidation of O2− on charging often results in loss of oxygen from the lattice. In the case of Li2MnO3 all
