Unveiling the effect of molybdenum and titanium co-doping on degradation and electrochemical performance in Ni-rich cathodes
《Materials Reports(Energy)》2025年第1期32-42,共11页Imesha Rambukwella Konstantin L.Firestein Yanan Xu Ziqi Sun Shanqing Zhang Cheng Yan 
support from Queensland University of Technology,Brisbane,Queensland,Australia;financial support from ARC Discovery Project(DP210103266).
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(Ni_(0.89)Co_(0.05)Mn_(0.05)Mo_(0.005)Ti_(0.005))O_(2) holds a stable struc...
