Abstract
The lithium oxygen (Li–O2) battery is one of the most promising technologies among various electrochemical energy storage systems. The challenge to develop a high-performance Li–O2 battery lies in exploring an air electrode with optimal porous structure and high efficient bifunctional electrocatalyst. The present work demonstrates a bioinspired synthesis route for the preparation of high performance Li–O2 air electrode materials that are made out of N-doped carbon foams decorated with heteronanostructured MoO2/Mo2C nanocrystals (MoO2/Mo2C@3D NCF). Here, recombinant proteins (ELK16-FLAG) facilitated the self-assembly of metal precursors and provided a carbon source for Mo2C formation. The as-prepared MoO2/Mo2C@3D NCF showed superior electrocatalytic activity in both oxygen evolution reaction and oxygen reduction reaction mechanisms with a high round-trip efficiency of 89.1% (2.77 V/3.11 V) at 100 mA g–1 as well as exceptional rate performances and good cyclability in Li–O2 battery. The desirable electroche...
