The positive role of (NH4)3AlF6 coating on Li[Li0.2Ni0.2Mn0.6]O2 oxide as the cathode material for lithium-ion batteries

“…Various coating materials have been explored, such as metal oxides (Al 2 O 3 , ZnO, MgO, Sm 2 O 3 , MoO 3 , etc. ), [27][28][29][30][31] metal phosphates (AlPO 4 , FePO 4 , LiNiPO 4 ), [32][33][34] metal uorides (AlF 3 , CeF 3 ), 35,36 38 These coating materials have been proved to either protect the interface between the cathode and electrolyte or reduce the charge transfer resistance, thus enhancing the cycling stability, rate capability, or other electrochemical performance factors.…”

Enhanced Electrochemical Properties of Zr4+-doped Li1.20[Mn0.52Ni0.20Co0.08]O2 Cathode Material for Lithium-ion Battery at Elevated Temperature

“…It has proved that the Zr 4+ doping modification can enhance the specific capacity and cycling performance of the Li 1.20 [Mn 0.52 Ni 0.20 Co 0.08 ]O 2 cathode, owing to the lower cation mixing and faster Li + migration speed for the Zr 4+ -doped samples. Besides, the discharge voltage plateau will gradually decrease during the cyclic process, owing to the enlargement of polarization and the formation of spinel-like phase for cathode materials 35 . It can be observed that the discharge voltage drops to lower plateau for the all cathodes after different cycles, as the arrows pointed in Fig.…”

Geometric consideration of nanostructures for energy storage systems

“…To date, battery systems have shown a wide range of selections in terms of diffusivity (Cathode: 10 À8 -10 À15 cm 2 /s from LiCoO 2 , LiMn 2 O 4 , and LiFePO 4 , Anode: 10 À9 -10 À13 cm 2 /s from graphite, germanium, and silicon) and film dimensions (1-100 lm) for different target rates (e.g., 10-20 C for Hybrid Electric Vehicles and 5 C for Electric Vehicles).
