文摘
- •
LiNi0.5Mn1.5O4 is obtained via in continuous co-precipitation synthesis.
- •
The material shows high tap-density, controlled particle size and architecture.
- •
Additional thermal treatments allow controlled stoichiometry variations.
- •
Additional annealing allows controlled crystallites growth.
- •
Ordered material with small crystallites and particles give the best performance.
