2020年4月1日 · The reported LiMn2O4 displays higher initial capacity retention and coulombic efficiency than several pristine and some doped LiMn2O4 cathodes cycled at various temperatures namely at 45 °C before Al-doping (C/C0 = 0.88) [36], at 55 °C before Co-doping (C/C0 = 0.65) [60], and at 55 °C pristine LiMn2O4 (C/C0 = 0.40) [51].

2024年8月27日 · We demonstrate that the increased entropy in LiMn 2 O 4 leads to an increase in the disordering of dopant cations and a contracted local structure, where the enlarged LiO 4 space and enhanced...

2021年8月12日 · The authors report a 1st-principles study of defect thermodn. and transport in spinel-type LiMn2O4, an important Li-ion battery electrode material, using d.-functional theory and the Heyd-Scuseria-Ernzerhof screened hybrid functional. Intrinsic point defects in LiMn2O4 have low formation energies and hence can occur with high concns.
