Abstract: Lithium-ion batteries (LIBs) can provide high energy density, while supercapacitors have superior advantages on high power density and long cycle life. Capacitive lithium-ion batteries are constructed by adding slight capacitive carbon materials into the regular cathode materials of LIBs to realize the combination of the LIBs and supercapacitors, and thus the power performance and cycle life of the devices can be substantially improved at the expense of slightly reduced energy density. In this paper, we summarize the recent progress in the development on capacitive lithium-ion batteries and introduce the dominating capacitive lithium-ion battery system and their electrochemical performance. Finally challenges and perspectives of the capacitive lithium-ion batteries are outlined.

Key words: capacitive lithium-ion battery, cathode, activated carbon, energy density, power density
