摘要
超级电容器具有功率密度高、循环寿命长和安全可靠等优点,在电动汽车、轨道交通、新能源、电磁弹射和激光武器等领域已广泛应用。然而,作为超级电容器的关键电极材料——活性炭,始终未实现国产化,一直依赖从日本和韩国进口,极大地制约了国内超级电容器及其下游产业的发展。本文综述了超级电容器用活性炭的理化性能对其电化学性能的影响,介绍了国内外超级电容器用活性炭产业现状,指出了其生产过程中制约产品品质的典型传质和传热等化工问题。文章提出,应在现有活性炭基础上建立全面合理的超级电容器用活性炭指标体系,从而指导其国产化工艺开发。针对其生产工艺和装备开展仿真模拟研究,以解决国产炭材料批次稳定性和一致性的问题,保障超级电容器行业关键材料自主可控。
Supercapacitors have widely been applied in electric vehicle,rail traffic,new energy,electromagnetic launch and laser weapons owing to their high power density,long cycling life,safety and reliability.However,the active carbon,as key electrodes for supercapacitor,is still imported from Japan and South Korea due to the lack of domestic industrialization,which greatly restricts the development of supercapacitors and their downstream industry.This paper summarized the effect of physical and chemical property of active carbons on its electrochemical performances and the industry status of active carbons for supercapacitors.The heat and mass transfer issues during the productive process that limited the quality of active carbons were also discussed.To better guide the domestic industrialization,it was highly desired to establish the comprehensive index system of active carbon for supercapacitor based on the current technology.Meanwhile,simulation study focused on manufacturing technique and equipment was needed to solve the problems of poor stability and consistency of domestic active carbon,ensuring the independence controllable production of critical materials for supercapacitor industry.
