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. © 2013 The Electrochemical Society.

Over last few years intense scientific research is in progress in the area of higher energy density batteries. Magnesium and aluminum metal anodes due to their multivalent nature can be used to obtain higher energy density (energy per unit volume) improved safety and lower initial and cycle-life costs than state-of-art lithium batteries. The introduction of electric vehicles (EVs) and plug-in hybrid vehicles (PHVs) via the use of battery technologies as stand-alone energy sources is slowly transforming the face of automobile industry and adding pressure, on battery research
