Air Cathodes and Bifunctional Oxygen Electrocatalysts for Aqueous Metal-Air Batteries

One of the most popular solutions for electrochemical energy storage is metal-air batteries, which could be employed in electric vehicles or grid energy storage. Metal-air batteries have a higher theoretical energy density than lithium-ion batteries. The crucial components for the best performance of batteries are the air cathode electrocatalysts and corresponding electrolytes. Herein, we present several of the latest studies on electrocatalysts for air cathodes and bifunctional oxygen electrocatalysts for aqueous zinc-air and aluminium-air batteries.
