Abstract

An organic dual-ion battery with a 5,7,12,14-pentacenetetrone anode for the reversible interaction of 1-butyl-1-methylpyrrolidinium cations was designed, which showed a low self-discharge rate of 4.68% per h, a high discharge capacity of 164.5 mA h g?1, and a superior capacity retention of 92.2% after 100 cycles at 5C.
