Tuning the Bifunctional Oxygen Electrocatalytic Properties of Core–Shell Co₃O₄@NiFe LDH Catalysts for Zn–Air Batteries: Effects of Interfacial Cation Valences

Abstract

); the rechargeable battery can show superior reversibility, excellent stability, and voltage gaps of ∼0.8 V (∼60% of round-trip efficiency) in >1200 continuous cycles. Furthermore, the flexible quasi-solid-state zinc-air battery with bendable ability holds practical potential in portable and wearable electronic devices.
