钾离子电池碳基负极材料研究进展OA北大核心CSTPCD

The widespread use of lithium batteries has led to a global problem of dwindling lithium re-sources and rising prices.Potassium ion batteries may serve as a substitute for lithium ion batteries due to their abundant raw material reserves.Carbon-based materials are inexpensive and possess a special porous structure,good conductivity,and stable electrode characteristics among all types of po-tassium anode materials.In recent years,numerous related studies have been reported,making it nec-essary to summarize the research on carbon anode materials in potassium electricity.The related re-search of potassium carbon based anode materials at home and abroad in recent years was reviewed from three aspects of soft carbon,hard carbon and graphite.The methods of material modification,specific capacity,cycle performance,rate performance,and influencing factors were analyzed and summarized.The future development direction of potassium carbon-based anode materials in achiev-ing high reversible capacity and long cycle stability was forecasted.
