Abstract

In situ BaSO4 coating, generated in the first discharging of Ba2+ pre-intercalated δ-MnO2, shortens the activation process by inducing fast proton intercalation and stabilizes the MnO2 crystal by suppressing Mn dissolution. The cathode delivers a decent electrochemical performance of 210 mA h g−1 at 1C with a 98% retention after 200 cycles. [ABSTRACT FROM AUTHOR]

Abstract

Herein, a bi-functional homogeneous redox mediator is employed to promote the rate capability of Li–O2 batteries. The addition of this redox mediator not only facilitates the formation of toroid-shaped Li2O2 at high current densities, but also significantly reduces the charging over-potential caused by the bulky Li2O2.
