The Characteristics of Fine-Sized LiMn_(12-X)/6Al_x/6O₄(0.05≤x≤2) Powders Prepared by Spray Pyrolysis

Abstract:

The series of partially Al-substituted lithium manganese oxides were prepared by spray pyrolysis process from spray solutions with citric acid and ethylene glycol. The as-prepared particles obtained from spray solution with citric acid and ethylene glycol turned to fine-sized LiMn(12- x)/6Alx/6O4(0.05≤x≤2) particles with regular morphology after post-annealing. The discharge capacities of the particles post-annealed at temperature of 800oC changed from 128 to 84 mAh/g when the x of the LiMn(12-x)/6Alx/6O4 particles was changed from 0 to 2. The Al-doped LiMn2O4 fine particles prepared by spray pyrolysis from spray solution with citric acid and ethylene glycol had good cycle properties.
