The Enormous Potential of Sodium/Potassium‐Ion Batteries as the Mainstream Energy Storage Technology for Large‐Scale Commercial Applications

Abstract Cost‐effectiveness plays a decisive role in sustainable operating of rechargeable batteries. As such, the low cost‐consumption of sodium‐ion batteries (SIBs) and potassium‐ion batteries (PIBs) provides a promising direction for “how do SIBs/PIBs replace Li‐ion batteries (LIBs) counterparts” based on their resource abundance and advanced electrochemical performance. To rationalize the SIBs/PIBs technologies as alternatives to LIBs from the unit energy cost perspective, this review gives the specific criteria for their energy density at possible electrode‐price grades and various battery‐longevity levels. The cost ($ kWh −1 cycle −1 ) advantage of SIBs/PIBs is ascertained by the cheap raw‐material…
