Unveiling the effect of molybdenum and titanium co-doping on degradation and electrochemical performance in Ni-rich cathodes

In this work, we have applied molybdenum (Mo) and titanium (Ti) co-doping to solve the degradation of Ni-rich cathodes. The modified cathode, i.e., Li(Ni0.89Co0.05Mn0.05Mo0.005Ti0.005)O2 holds a stable structure with expanded crystal lattice distance which improves Li ion diffusion kinetics. The dop...
