Herein, a novel rocking-chair aqueous AIB, based on the Ni-PBA inorganic cathode and PTO organic anode, is presented. This device showed an excellent cycle life and high efficiency, endowed with a high capacity-retention of 96.0% and coulombic efficiency (CE) of over 99% at 1 A g-1 after 5000 cycles. The environmentally friendly and ultralong-life aqueous AIBs are expected to provide new options for next-generation energy storage devices.
