Sodium-ion batteries: Storage solution or Illusion of attraction AbstractSodium-ion batteries (SIBs) have attracted much interest as an alternative to lithium-ion batteries for energy storage due to their low cost and natural abundance of sodium resources [14–17]. Furthermore, as nature possesses large amount of sodium and it can provide a replacement for the lithium chemistry, the sodium-ion batteries could be a competitor to the lithium-ion batteries in commercial markets. The abundance of sodium can be estimated by the fact that 23 billion of soda ash that is regarded as sodium precursor is only located in the United States. Researches have shown
