摘要
超级电容器是一类新型的电化学能量存储器,具有功率密度高、充放电速度快和寿命长等优势。探究碳基锂离子超级电容器负极预嵌锂方法,通过对以炭为主要原料的负极材料实施一系列处理工艺,可得到预嵌锂炭材料。通过对预嵌锂炭材料的物理性能、电化学性能以及电容性能的测试,证明了该预嵌锂方法可显著提高超级电容器的能量密度、功率密度和循环稳定性。此外,还探讨了该预嵌锂方法的机理,并对其可能的应用前景进行了展望,对碳基锂离子超级电容器的开发和应用具有重要的理论和实际意义。
Supercapacitor is a new type of electrochemical energy storage features high power density,fast charge and discharge,and long service life.The present work aimed at a rational method of pre-intercalating lithium on anodes of carbon-based lithium-ion supercapacitors.The carbon anode with pre-intercalation of lithium was obtained by implementing a series of treatment processes.Measurements including physical properties,electrochemical properties and capacity properties of the pre-intercalated carbon materials proved that pre-intercalation of lithium can significantly improve energy density,power density and cyclic stability of the supercapacitor.In addition,the mechanism of the pre-intercalation method and its possible application prospects are also discussed.The present work may be helpful for development and application of carbon-based lithium-ion supercapacitors.
