摘要：

Synthesis of nanocrystallite gamma-LiAlO2 from spent lithium-ion batteries has been investigated. XRD results show that gamma-LiAlO2 phase can be synthesized by thermal treatment of the cathode material over its aluminum sheet at 800-900 degrees C for 2 h. This is accompanied with the formation of Co3O4 and CoO phases as colored powders. SEM investigation revealed the formation of dense grains as coconut-like shape structure of gamma-LiAlO2 phase. Comparatively, reaction of chemical grade Al powder with LiOH in stoichiometric ratio at 800 degrees C gives gamma-LiAlO2 phase of cotton-like morphology. (c) 2006 Elsevier B.V. All rights reserved.
