One-pot synthesis of FeNxC as efficient catalyst for high-performance zinc-air battery

Rechargeable zinc-air batteries (ZAB) with a high theoretical energy density of 1086 Wh kg−1, have received tremendous research attention. However, the practical application of ZABs is still limited by high polarization and poor energy efficiency (low power density) due to the sluggish 4 electrons (e−)/oxygen (O2) kinetics over the air electrode. Here, a noble-metal-free FeNxC electrocatalyst is developed via a one-pot approach, which provides a...
