Synthesis and characterization of Ammonium Hexachlorostannate perovskite and its application as cathode material in Lithium-ion batteries

One of the most interesting topics in energy storage area is the use of organic–inorganic hybrids materials due to the possibility of integrating properties of inorganic and organic molecules such as electrical, optical and conductivity properties. Specifically, the selection of metals such as Tin (Sn) may offer unique chemical structure and properties that could potentially lead to enhance energy storage devices performance such as batteries. In this work, the synthesis of (NH ₄ ) ₂ SnCl ₆ as cathode material for Li-ion batteries was carried out following a simple chemical precipitation method. The material was characterized by X-ray diffraction to analyze the crystallographic structure and SEM to analyze the morphology of the active compound also, IR spectrum was recorded. The inorganic-organic material was tested in a CR2032 coin cell configuration and its electrochemical properties were measured. Cyclic voltammetry was used to analyze the oxidation-reduction phenomena, several features were observed within a voltage range from 0.01 to 2V Discharge/charge process were investigated. The obtained discharge capacity was close to 160 mAhg ^− 1 at 20 mAg ^− 1 .
