Abstract:

Large-scale energy storage is a pivotal part of the carbon neutrality and multi-energy complementation ecosystem, a bridge between clean energy and smart grid, and an important measure to ensure national energy security. The advanced secondary batteries are the key technology for large-scale energy storage. Sodium batteries based on oxide solid electrolytes (OSSBs), especially those with liquid metal sodium as the anode, are considered as one of the most promising and valuable grid-scale energy storage technologies owing to its high power density and abundant resources. However, there are still several shortcomings for OSSBs in terms of cycle stability, safety and cost, which prevent their practical applications. Importantly, strategies on how to effectively regulate the surface/interface electrochemical behavior of OSSBs and improve the energy storage performance while reducing the cost have become the focus of the current research. This review focuses on the research progress of OSSBs in recent years, mainly for the typical systems such as sodium-sulfur batteries and sodium-metal chloride batteries. We analyze the development of OSSBs from several key aspects, such as cost control, operating temperature reduction and application reliability optimization, and further propose the future prospects.

Key words: large-scale energy storage, high-temperature sodium battery, sodium-sulfur battery, sodium-metal chloride battery, Zebra battery
