摘要

Recent advances in the development of energy storage devices are focused on the searching for new materials that enhance the capabilities and performance of these devices. In this context several compounds have been proposed and synthetized as potential cathodes based in an organic-inorganic configuration since they can improve the battery’s energy density, power output and cycle life. Building on this concept, the present study proposes the incorporation of diguanidinium hexachlorostannate as a potential cathode material for lithium-ion batteries, motivated by its promising performance when used as an electrolyte component. The guanidinium molecule is capable to form several ionic complexes and it is chemically stable, which enables it as a flexible organic cation for its incorporation in hybrid perovskites. In this work, the synthesis of diguanidinium hexachlorostannate was carried out through an easy cooling synthesis method and its structural and morphological characteristics were investigated by X-ray diffraction measurements, Infrared spectroscopy and Scanning Electron images; the electrochemical performance of fabricated cathodes for lithium-ion batteries was explored via galvanostatic and potentiostatic evaluations. The electrochemical results revealed a moderate capacity of 114 A h Kg− 1 at 20 A Kg− 1 with an overall capacity retention efficiency of 83% after 50 cycles.
