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)/6Al_x/6O₄(0.05≤x≤2) particles with regular morphology after post-annealing. The discharge capacities of the particles post-annealed at temperature of 800°C changed from 128 to 84 mAh/g when the x of the LiMn_(12-x)/6Al_x/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.
