CATHODE MATERIAL FOR FLUORIDE-BASED CONVERSION ELECTRODES, METHOD FOR THE PRODUCTION THEREOF AND USE THEREOF

摘要

A cathode material for fluoride-based conversion electrodes includes a matrix of graphite nanocarbon containing a dispersion of alkali metal ions, fluoride ions and metal nanoparticles with maximum particle sizes of 20 nm. Further there is provides a method for such cathode material that includes heating a metal and an organic compound during a single thermal treatment step until the organic compound is decomposed; and adding an alkali metal fluoride either before or after the thermal treatment step to the organic compound. Finally, there is provided a method of making an alkali metal ion battery, that includes utilizing the aforesaid cathode material for a fluoride-based conversion electrode in the battery.
