Abstract Carbon materials, including graphite, hard carbon, soft graphene, and carbon nanotubes, are widely used as high‐performance negative electrodes for sodium‐ion potassium‐ion batteries (SIBs PIBs). Compared with other materials abundant, low‐cost, environmentally friendly, have excellent electrochemical properties, which make them especially suitable electrode of SIBs PIBs. traditional modifications the morphology size nanomaterials represent effective strategies to improve quality materials. Different nanostructures different contributions toward improving performance so synthesis is promising controlling This paper reviews progress made challenges in use PIBs recent years. The differences Na + K storage mechanisms among types emphasized.
