Study of structural and composition redesign to enhance the thermostability and electrochemical performance of a Co-less Ni-rich LiNi0.92Co0.04Mn0.04O2 layered cathode through transition-metal concentration gradient strategies

Among the commercialized cathodes, Co-less Ni-rich layered cathode materials (Ni > 90%) have been reported as promising materials to achieve high energy density and economically benign cathodes for Li-ion batteries (LIBs).
