锂离子混合超级电容器电极材料研究进展

Abstract

Nowadays, the rapid development of new energy system and electronic devices drives an increasing demand for energy storage equipments. Lithium ion hybrid supercapacitors, combining two different storage mechanisms of lithium-ion batteries and supercapacitors, have exhibited excellent properties such as high energy and power density, long cycling life and high safety. Due to these advantages, lithium ion hybrid supercapacitors have become a promising energy storage device for next generation of electric vehicles and hybrid electric vehicles. In this paper, we introduced respectively the characteristics and future study trend of lithium ion batteries and supercapacitors, and summarized the inherent characteristics of lithium ion hybrid supercapacitors and the corresponding three typical charge/discharge mechanisms. In addition, according to the different hybrid systems, we also summarized the research progress of non aqueous lithium ion hybrid supercapacitors in recent years.
