Potassium-ion batteries (PIBs) are regarded as a potential substitute for LIBs owing to the benefits of potassium’s abundance, low cost, and high safety. Nonetheless, practical implementation potassium-ion still encounters numerous challenges, with selection design anode materials standing out key factor impeding their progress. Hard carbon, characterized by its amorphous structure, specific surface area, well-developed pore facilitates insertion/extraction potassium ions, demonstrating excellent rate performance cycling stability. This review synthesizes recent advancements in hard carbon utilized PIB anodes, particular focus on storage mechanism, electrochemical properties, modification strategies carbon. Ultimately, we present summary current challenges future development directions materials, objective providing reference optimization PIBs.
