The usable charge storage capacity of NCA is about 180 to 200 mAh/g. [1] This is well below the theoretical values; for LiNi 0.8 Co 0.15 Al 0.05 O 2 this is 279 mAh/g. [2] However, the capacity of NCA is significantly higher than that of alternative materials such as lithium cobalt oxide LiCoO 2 with 148 mAh/g, lithium iron phosphate LiFePO 4 with 165 mAh/g and NMC 333 LiNi 0.33 Mn 0.33 Co 0. ...
