Design of Nb5+-doped high-nickel layered ternary cathode material and its structure stability

Tingting Zhao,
Pei Liu,
Fuli Tang
et al.

Abstract: LiNi0.8Co0.1Mn0.1O2 (NCM811) is one of the most promising cathode materials for high-energy lithium-ion batteries, but there are still problems such as rapid capacity decay during charge and discharge and poor cycle performance. Elemental doping can significantly improve the electrochemical performance of high nickel ternary cathode materials. In this work, Nb5+-doped NCM811 cathode material was successfully synthesized. The results show that Nb5+ doping helps to increase the interlayer spacing of the lithium … Show more
