Solvothermal synthesis-driven quaternary Ni-rich cathode for stability-improved Li-ion batteries
Recently, Ni-rich ternary transition metal oxides (Li(NiCoMn)O2, NCM) containing more than 80% Ni have been extensively studied as high-capacity cathodes. Herein, we synthesized a quaternary cathode, Ni-rich Al-doped NCM, using a facile solvothermal method without an additional Al doping process. Co...

| description | Recently, Ni-rich ternary transition metal oxides (Li(NiCoMn)O2, NCM) containing more than 80% Ni have been extensively studied as high-capacity cathodes. Herein, we synthesized a quaternary cathode, Ni-rich Al-doped NCM, using a facile solvothermal method without an additional Al doping process. Compared to an undoped NCM cathode, the quaternary Ni-rich cathode exhibited improved lithium-ion battery performance (retentions of 82.0% and 65.8% after 100 and 250 cycles, respectively). In particular, the superior stability of the quaternary Ni-rich cathode may result from the stable cathode structure resulting from Al doping. |
