摘要
锂离子电容器一个电极采用电池型负极,一个采用电容型正极,因而兼具高能量密度、高功率密度的优点,有望成下一代新型储能器件。基于Faraday反应的电池型电极与电容型电极动力学不匹配是锂离子电容器的一个巨大挑战,因此研究者们发展了多种倍率性锂离子电池材料。在这些材料中,钒基材料以其成本低、比容量大、倍率性能优异等优点被认为是锂离子电容器的理想负极材料。综述了包括Li_(3)VO_(4)、VN、Li_(3)V_(2)O_(5)在内的多种不同类型钒基锂离子电池材料的储锂机理与性能优化的研究进展,并展望了锂离子电容器中钒基负极材料的发展方向。
Lithium-ion capacitor has structure of consisting of the battery-type anode and capacitor-type cathode,thus having a enabling high energy density and a high power density.This capacitor expected to become the next generation of new energy storage devices.The kinetic mismatch between the Faradaic battery-type anode and capacitive cathode is a great challenge for lithium-ion capacitors.Therefore,researchers have developed a variety of high-rate lithium-ion battery materials.Among these materials,vanadium-based materials are considered as ideal anode materials for lithium-ion capacitor due to their low cost,large specific capacity,and superior rate performance.This review summarized recent work on the optimization strategies of several vanadium-based anode materials,i.e.Li_(3)VO_(4),VN and Li_(3)V_(2)O_(5).In addition,the future directions in the application of vanadium-based anode materials for lithium-ion capacitor were also proposed.
