钾离子电池碳基负极材料的研究进展

Research Progress of Carbon-Based Anode Materials for Potassium Ion Batteries

钾离子电池被认为是较理想的锂离子电池替代者,其具有钾资源储量丰富、成本低廉、输出电压高等优势。当前,碳基材料因安全稳定性高等优势依然被认为是最具潜力的商用钾离子电池负极材料,受到广泛研究。基于此,对近两年石墨、软碳、硬碳、活性炭、碳纤维等碳基材料作为钾离子负极材料的研究进展进行综述,并展望了碳基材料作为钾离子电池负极材料的发展前景。

Potassium ion batteries have been considered to be the ideal replacement for lithium ion batteries because they possess the advantages of abundant potassium resources,low cost,high output voltage.At present,carbon-based materials are still considered to be the most potential commercial potassium ion battery anode materials due to their high safety and stability advantages,and have been widely studied.In this paper,the research progress of carbon based materials such as graphite,soft carbon,hard carbon,active carbon and carbon fiber as potassium ion anode materials in the past two years is reviewed,and the development prospect of carbon based materials as potassium ion battery anode materials is prospected.
