In article number 1600605, Yongbing Tang and co‐workers report a novel dual‐ion battery constructed with aluminum foil anode and mesocarbon microbead cathode based on an ionic liquid electrolyte. The battery works at high cut‐off voltage of 4.8 V with a reversible capacity of ≈100 mAh g −1 and shows good cycling stability for 300 cycles. Moreover, it achieves high energy density of 185 W h kg −1 at 1141 W kg −1 , much higher than most commercial lithium‐ion batteries.
