Summary: In this study, sulfur-doped porous carbons were prepared and showed improved performance for potassium-ion batteries, with higher specific capacity, better rate capability, and enhanced cycling stability. The excellent electrochemical performance is attributed to the abundant porous structure and sulfur doping, which provide sufficient reaction sites and fast ion/electron transport paths. Additionally, density functional theory calculations confirm that sulfur doping can enhance potassium-ion adsorption and storage, and kinetic analyses suggest that surface-induced capacitive mechanism dominates the potassium-ion storage process in sulfur-doped porous carbons, enabling ultrafast charge storage.

Summary: Biochar materials have gained attention due to their environmental friendliness, abundant resources, and use of waste resources for reuse. As a potassium-ion anode material, biomass char materials synthesized through different methods show promising application prospects. However, their low initial magnification and limited potassium-storage capacity call for improvements through modifications, such as atomic doping. Atomic doping proves to be an effective approach in enhancing battery conductivity and potassium storage. This paper reviews the synthesis method of biochar as a potassium-ion battery anode material and the impact of atomic doping on its modification in recent years.
