Continuous Fabrication of MnS/Co Nanofibrous Air Electrode for Wide Integration of Rechargeable Zinc-Air Battery

Abstract

Exploring highly efficient bifunctional electrocatalysts toward oxygen reduction and evolution reactions is essential to the realization of high-performance rechargeable zinc–air batteries. Herein, a novel nanofibrous bifunctional electrocatalyst film, consisting of metallic manganese sulfide and cobalt encapsulated by nitrogen-doped carbon nanofibers (CMS/NCNF) is prepared through a continuous electrospinning method followed with carbonization treatment. The CMS/NCNF bifunctional catalyst shows both comparable ORR and OER performances to those of the commercial precious metal-based catalysts. Furthermore, the free-standing CMS/NCNF fibrous thin film is directly used as the air electrode in solid-state zinc-air battery, which exhibits superior flexibility while retaining stable battery performance under different bending angles. This study provides a versatile design route for rational design of the free-standing bifunctional catalyst for direct use as the air electrode in rechargeable zinc-air batteries.
