Although layered lithium oxides have become the cathode of choice for state-of-the-art Li-ion batteries, substantial gaps remain between the practical and theoretical energy densities. With the aim of supporting efforts to close this gap, this work reviews the fundamental operating mechanisms and challenges of Li intercalation in layered oxides, contrasts how these challenges play out differently for different materials (with emphasis on Ni–Co–Al (NCA) and Ni–Mn–Co (NMC) alloys), and summarizes the extensive corpus of modifications and extensions to the layered lithium oxides. Particular emphasis is given to the fundamental mechanisms behind the operation and degradation of layered intercalation electrode materials as well as novel modifications and extensions, including Na-ion and cation-disordered materials. Li intercalation in layered-oxide cathodes involves a complex interplay between many thermodynamic and kinetic phenomena. This review summarizes the fundamental mechanisms and challenges, and how these play out for different layered-oxide cathode materials. Special emphasis is given to Ni–Co–Al and Ni–Mn–Co alloys as well as novel modifications and extensions, including Na-ion and cation-disordered materials.
