NCA, NCM811, and the Route to Ni-Richer Lithium-Ion Batteries

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.
