Advanced hybrid Li–air batteries with high-performance mesoporous nanocatalysts†
Abstract
Hybrid Li–air batteries fabricated with mesoporous NiCo2O4 nanoflakes directly grown onto nickel foam and N-doped mesoporous carbon loaded onto a hydrophobic carbon paper, respectively, as the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) catalysts are found to exhibit the best reported cycle life.
