31 Οκτ 2022 · The results reveal that there is more oxygen release and lower initial temperature of phase transition with increasing of Ni contents. The effect between Li + vacancies and Ni 2+ raised Ni 3+ during Li +-deintercalation process can intensify oxygen loss, and form more NiO compounds in local coordination structure unit .
28 Απρ 2022 · The synergistic effect of Al/Zr co-doping in SNCM lattice improve the Li-ion mobility, relief the internal strain, and suppress the Li/Ni cation mixing upon cycling at high cut-off voltage.
6 Φεβ 2019 · Abstract. As a derivative of LiNiO 2, NCA (LiNi 1-x-y Co x Al y O 2) is widely used in the electric vehicle industry because of its high energy density. It is thought that Co and Al both play important roles in enhancing NCA material properties.
10 Ιουν 2019 · However, structural disorder as a result of Ni/Li exchange in octahedral sites becomes a critical issue when Ni content increases to high values, as it leads to a detrimental effect on Li diffusivity, cycling stability, first-cycle efficiency, and overall electrode performance.
22 Απρ 2020 · Bo Wang, Jing Cui, Zhaojin Li, Huan Wang, Di Zhang, Qiujun Wang, Huilan Sun, Yimin A. Wu. Review on comprehending and enhancing the initial coulombic efficiency of Li-rich Mn-based cathode materials in lithium-ion batteries. Materials Chemistry Frontiers 2023, 7 (13) , 2570-2594.
