Abstract: The aim of this article is to examine the progress achieved in the recent years on two advanced cathode materials for EV Li-ion batteries, namely Ni-rich layered oxides LiNi 0.8 Co 0.15 Al 0.05 O 2 (NCA) and LiNi 0.8 Co 0.1 Mn 0.1 O 2 (NCM811). Both materials have the common layered (two-dimensional) crystal network isostructural with LiCoO 2 . The performance of these electrode materials are examined, the mitigation of their drawbacks (i.e., antisite defects, microcracks, surface side reactions) are discussed, together with the prospect on a next generation of Li-ion batteries with Co-free Ni-rich Li-ion batteries.
