"Research Progress and Future Perspectives on Rechargeable Na-O sub 2 /" by Zhi Zheng, Chang Wu et al.
Abstract Rechargeable sodium–oxygen (Na-O ) and sodium–carbon dioxide (Na-CO ) batteries have attracted intensive research attention in recent years owing to their advantages of high theoretical energy density, modest cost, abundance of sodium resources, and promising potential for achieving real sodium–air batteries in large-scale energy storage systems. Nevertheless, current research on Na-O and Na-CO batteries is facing enormous challenges, such as low energy efficiency and limited cycle life, which are restricting their progress at the initial stage. Therefore, understanding their...
