摘要
电化学电容器(也称为超级电容器)是一种介于电池和传统电容器之间的新型的储能器件,兼具电池的高能量密度和传统电容器的高功率密度特性,在电化学储能领域中具有广泛的应用前景~([1,2])。多孔炭作为目前广为使用的一种超级电容器电极材料,以其高电导率、高比表面积及可控的孔隙结构受到研究者的广泛青睐。我们以锡化合物为活化剂,以聚乙烯醇为炭源,通过水热合成制备含锡前驱体复合材料,经炭化后得到三维分级多孔炭超级电容器电极材料。通过控制反应条件实现对所制备多级孔电极材料微观形貌、尺寸、孔结构的优化,得到了性能优良的多孔碳材料并研究了它们的双电层电容性能。
Electrochemical capacitors(ECs) are recognized as a promising new energy-storage device to fill the gap between batteries and conventional capacitors.Porous carbon materials have been proven to be a popular candidate in ECs due to their high electrical conductivity,high SSA,controllable porous texture,and relatively low cost.We present an efficient strategy to fabricate monolithic porous carbon materials through a facile hydrothermcarbonization method by employing tin oxide as porogen and polyvinyl alcohol as carbon precursor.In addition,the samples' specific surface area,microstructure and pore size have been investigated by controlling preparation process to obtain high-performance electrode materials for electrochemical capacitors.
