A novel low‐cost aluminum–graphite dual‐ion battery is reported. The battery shows a reversible capacity of ≈100 mAh g −1 and a capacity retention of 88% after 200 charge–discharge cycles. A packaged aluminum–graphite battery is estimated to deliver an energy density of ≈150 Wh kg −1 at a power density of ≈1200 W kg −1 , which is ≈50% higher than most commercial lithium ion batteries.
