Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT With high theoretical capacity and low cost, bismuth sulfide (Bi2S3) demonstrates considerable potential as an anode for sodium/potassium‐ion batteries (SIBs/PIBs). Unfortunately, significant volume variation, low electrical conductivity, and dissolution of polysulfides drastically weaken their intrinsic merits.
