Abstract:

Rechargeable sodium-air batteries have been the focus in recent years, owing to the low cost and natural abundance of sodium and high energy density. The discovered different electrochemical mechanism from other metal-air batteries bring unique advantages and challenges to the development of sodium-air batteries. This review comprehensively conclude the key problems and development of different electrochemical mechanism. In the last, remarks are made on the further developments of sodium-air batteries.

Key words: secondary sodium-air batteries, high energy density, reaction mechanism
