摘要: Various Ni-rich layered oxide cathodes (above 0.80 Ni content), such as LiNi1� yzCoyAlzO2 (NCA), are used in electric vehicles (EVs) due to their high capacity (~200 mAh g � 1 for NCA). However, improve cycle performance and thermal stability ensure longer safer usage, numerous studies have investigated surface modification, coating, doping of cathode materials. In this study, we the characteristics Li(Ni0.85CoxMn0.15� x)O2 with various Mn Co ratios (x ¼ 0e0.15) synthesized by a coprecipitation method. The discharge capacities cath- odes similar at around 206 room temperature 213.8 55
