Abstract:
Lithium-ion capacitor (LIC), which combines the high power density of electric double-layer capacitors (EDLC) and high energy density of lithium-ion battery (LIB), vastly suiting the condition demand of electric city bus, energy-saving elevators and the tram, has attracted tremendous interests of researchers from both research institutes and enterprises. Here in this paper，the current advances containing the operating principle, electrode material system and the anode pre-doping technique of LIC are stated concisely. In addition, the self-developed novel LIC, reaching 20 Wh?kg-1 or higher for energy density, is introduced as the power supply of pure electric city bus pilot application. The running case as a result evidences that LIC has bright prospect when used for fixed-line electric city bus: ①more energy storing, which fulfills the whole course less than 20 km after charging once at the original station; ②advanced communication management system, which could monitor the working condition of LIC timely to prognosis the malfunction, thus improving safety; ③ progressive thermal management system, that the highest temperature of LIC cell is only 3~4 ℃ higher than that of the ambient environment can withstand the test of sizzler.
