An aluminum–ion battery comprised of fluorinated natural graphite cathode, aluminum anode and AlCl₃ containing imidazolium based ionic liquid as electrolyte is reported for the first time. Electrochemical method of preparation of fluorinated natural graphite lead to formation of non-covalent C-F bonds. The cycle life studies (40 cycles) of the battery indicated very stable electrochemical behavior and the discharge capacity of the battery is 225 mAh g⁻¹.

This review elaborates the effects of alloying elements on the microstructure, mechanical properties, corrosion and biocompatibility of biodegradable magnesium alloys.
