Nanostructured FeOF-FeF3 composite: synthesis and physicochemical properties
The efficiency of an original method of pulsed high-voltage discharge in synthesis of a nanostructured FeOF-FeF3 composite perspective for its application as an anode-active material for Li-ion battery has been demonstrated. It has been established that the composite particles consist of nanocrystallites ranging in sizes from 10 to 300 nm. Reversible capacitance of a nanostructured FeOF-FeF3 composite with respect to Li+/Li, realized after 10-fold discharge-charge cycling in the range from 3.0 to 0.005 V at current density of 10 mA/g was 210 mA·h/g. The electrochemical reaction mechanism between the Li+ and FeOF-FeF3 has been investigated by the cyclic voltammetry.
