Electrode materials LiNixMn2-xO4 with (x = 0; ; ; ) were synthesized by the sol-gel method from lithium acetate, manganese acetate and nikel acetate. The FESEMs show that the morphology of the material changes when the anealing temperature and the proportion replacement of Mn with Ni changes. XRDs confirmed that the samples have LiNixMn2-xO4 spinel structures without any contaminants. |
