Emerging battery applications (i.e. electric vehicles) demand increasingly higher energy density, lower cost, longer cycle life, and higher safety,all of which cannot be simultaneously met by current lithium ion battery technology. The cathode, specifically, is often identified as the limiting component for energy density and cost. LiNi0.8Mn0.1Co0.1O2 (NMC811) is a promising candidate for this space, offering an energy density over 20% higher than commercial cathode materials. However, its high nickel content also poses technical issues including cracking, low thermal stability, cation mixing, and parasitic reactions. In this project, an integrative approach including doping and coating was adopted to solve the above issues of NMC811.
