Abstract
- In the present work, we have synthesized nanocrystalline LiMn2O4 of different grain sizes, for application to Li ion rechargeable batteries. LiMn2O4 cathode powder was synthesized by sol-gel method and was high-energy ball milled for 8 and 16 h, respectively. The particle sizes of pure, 8 h, and 16 h ball-milled samples were determined from TEM and measured as ∼225, 40, and 10 nm, respectively. The initial discharge capacity of the pure LiMn2O4 cathode material was found to be about 128.75 mAh/g, which was found to decrease on reducing the particle size. [ABSTRACT FROM AUTHOR]
