OER highly active encapsulants to improve the electrochemical anticorrosion of Fe–N–C for ultralong-lifespan and high-rate rechargeable zinc–air batteries

Abstract

Oxygen catalytic activity: Δ E = 0.52 V. Carbon corrosion was alleviated by: (1) encapsulation by LDH that preferentially catalyzes OER and (2) depressing radical generation via fast disproportionation and electro-reduction/oxidation of peroxide.
