A super-long life rechargeable aluminum battery

A rechargeable aluminum battery (RAB) with a commercial ordered mesoporous carbon (CMK-3) as a cathode is proposed, which shows a super-long life of >36,000 charge/discharge cycles with a high coulombic efficiency of >97% and excellent rate performance up to 3000 mA g−1. The Al/CMK-3 battery has a high energy density of ~45 Wh kg−1.124
