Abstract

We report a new type of rechargeable chloride ion battery using vanadium oxychloride (VOCl) as cathode and magnesium or magnesium/magnesium chloride (MgCl₂/Mg) as anode, with an emphasis on the VOCl-MgCl₂/Mg full battery. The charge and discharge mechanism of the VOCl cathode has been investigated by X-ray diffraction, X-ray photoelectron spectroscopy, and electrochemical measurements, demonstrating the chloride ion transfer during cycling. The VOCl cathode can deliver a reversible capacity of 101 mAh g^-1 at a current density of 10 mA g^-1 and a capacity of 60 mAh g^-1 was retained after 53 cycles in this first study.
