摘要:

  鋰離子電容器兼具雙電層電容器的高功率密度與鋰離子電池的高能量密度特性，極大程度的滿足了電動公交車、節(jié)能電梯和有軌電車等的工況需求，成為近年來各科研院所和高新企業(yè)的研究熱點。從鋰離子電容器的工作原理、電極材料體系以及負(fù)極預(yù)嵌鋰技術(shù)等方面闡述了國內(nèi)外的相關(guān)研究進展，并系統(tǒng)的介紹了作者課題組自主開發(fā)的能量密度大于20Wh kg-1的鋰離子電容器在城市純電動公交車上的示范應(yīng)用。運行結(jié)果表明，鋰離子電容器在固定線路電動公交車領(lǐng)域具有良好的應(yīng)用前景：①儲能量大，實現(xiàn)20 km以下線路首站一次充電跑完全程；②先進的通訊管理系統(tǒng)，實時監(jiān)控鋰離子電容器運行情況，及早預(yù)判故障，提高運營安全；③先進的熱管理系統(tǒng)，電容單體的最高溫度僅比環(huán)境溫度高3~4 ℃，完全能夠承受高溫天氣的考驗。

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.
