      This report illustrates an investigation on the electrochemical stability of bismuth oxychloride (BiOCl) for rechargeable aluminium–metal battery for the first time. It is shown that Al$^{3+}$ ion could be stored in bismuth oxychloride in aqueous electrolyte. A stable discharge capacity of 145 mAh g$^{-1}$ was achieved over 200 cycles at a current rate of 2.5 A g$^{-1}$. It is found that capacity decline was a major concern. However, a simple and innovative strategy was adopted to dramatically improve the electrochemical stability by synthesizing a binder-free BiOCl electrode on a thermally exfoliated graphite current collector. The use of such current collector is also shown for the first time. The facile method of processing the exfoliated graphite is also discussed.
