Editorial: Sodium-ion batteries: From materials discovery and understanding to cell development

The rapid growth in the worldwide battery demand has accelerated the search for efficient, low cost 11 and sustainable batteries able to satisfy different markets including portable electronics, the electrified 12 mobility sector and stationary applications. Several emerging battery technologies are currently 13 considered to take the share of the dominant position taken by lithium-ion batteries (LIBs). Among 14 them, owing to their potential lower cost and higher sustainability, sodium-ion batteries (SIBs) have 15 the potential to dominate the future stationary storage market, and contribute to the electrified transport 16sector (Hasa et al., 2021;Tapia-ruiz et al., 2021). 17The growing interest in sodium-ion technology has been accelerated by the successes of several 18 companies investing in the technology (Bauer et al., 2018
