The lithium nickel cobalt aluminium oxides (abbreviated as Li-NCA, LNCA, or NCA) are a group of mixed metal oxides. Some of them are important due to their application in lithium-ion batteries. NCAs are used as active material in the positive electrode (which is the cathode when the battery is discharged). NCAs are composed of the cations of the chemical elements lithium, nickel, cobalt an. Properties of NCAThe usable charge storage capacity of NCA is about 180 to 200 mAh/g. This is well below the theoretical values; for. . NCAs LiNixCoyAlzO2 with x ≥ 0.8 are called nickel rich; those compounds are the most important variants of the substance class. The nickel-rich variants are also low in cobalt and therefore have a cost advantage. . To make NCA more resistant, in particular for batteries that need to operate at temperatures above 50 °C, the NCA active material is usually coated. The coatings demonstrated in research may comprise fluorides su. . The main producers of NCA and their market shares in 2015 were with 58%, Toda Kogyo (BASF) with 16%, Nihon Kagaku Sangyo with 13% and Ecopro with 5%. Sumitomo supplies Tesla and.
