摘要: 锂离子电容器属于非对称型超级电容器,通常由电池型负极和电容型正极共同置于有机锂盐溶液中组装而成,兼具超级电容器的高功率特性和锂离子电池的高能量密度,在智能电网、轨道交通、新能源汽车等多个领域具有广阔的应用前景。炭材料由于来源广泛、价格低廉、性能稳定,是锂离子电容器的首选电极材料。因此,炭基锂离子电容器具有竞争性的产业化前景。负极预嵌锂技术对于炭基锂离子电容器的电化学性能具有决定性影响。本文从锂源引入位置的角度,系统回顾了锂离子电容器负极预嵌锂技术的进展情况,并就负极预嵌锂过程中的关键控制因素做了梳理,有助于全面了解负极预嵌锂技术的研究现状,为锂离子电容器的进一步发展提供科学参考。

Abstract: Lithium-ion capacitor (LIC) consists of a battery-type anode and a capacitor-type cathode in the organic electrolyte containing lithium salts, combining the excellent power characteristics of a supercapacitor with the high energy density of a lithium-ion battery. It has a board application prospect on smart grid, rail transportation, hybrid electric vehicles and other fields. Because of a wide range of sources, low prices, stable performance, carbon materials are used as the preferred electrode material of LIC and carbon-based LIC has a competitive industrialization prospects. The negative electrode pre-lithiation technology has a decisive influence on the electrochemical performance of carbon-based LIC. Herein, the progress of pre-lithiation technology for LIC is systematically reviewed from the introduction of lithium source. The key factors in the process of pre-lithiation are also reviewed. It is helpful for the comprehensive understanding of the pre-lithiation technology research status, providing scientific reference for the further development of LIC.

Key words: lithium-ion capacitor, energy storage principal, negative electrode, lithium source, pre-lithiation
