Review of sodium-ion battery research

Sodium-ion batteries (SIBs) have gained increasing attention due to their low production cost, abundant raw materials, and relatively high energy density. In addition, SIBs exhibit a range of desirable characteristics, including high specific capacity, good high-temperature performance, safety, and environmental friendliness. Therefore, research into sodium-ion batteries is of paramount importance. This paper references a large number of studies on sodium-ion batteries, aiming to analyze and summarize the research issues related to SIBs and the impact of their development on societal progress. The paper primarily focuses on solid-state electrolytes, while also covering analysis of sodium-sulfur batteries, zebra batteries, sodium-air batteries, and aqueous sodium-ion batteries.
