Synthesis and Characterizations of LiSICON Li2Co2(MoO4)3 with Different Amounts of Starch

This paper describes a simple procedure to synthesize materials with NASICON-like structures, using starch as a mild combustion fuel. The results of ICP-MS, x-ray and Raman spectroscopy present that the samples can be classified as a solid solution and isostructural to Li2Co2(MoO4)(3). The analysis by x-ray diffraction shows that the increase on starch amount promotes crystallinity, leading to diffraction peaks more intense and better defined. Moreover, we can infer that the amount of starch increases substantially the material capacity (5 mAhg(-1) to 52 mAhg(-1)), as well leads to a better definition of the redox peaks.
