目的
2
设计同时具有高质量活性和高体积活性的锂离子电容器(lithium-ion capacitor,LIC)复合正极材料。
方法
2
借助扫描电子显微镜、透射电子显微镜、康塔全自动比表面和孔径分析仪、四探针测试仪,通过实验分析了颗粒之间的微观形貌、堆叠方式、接触模式和界面特性对复合电极的电导率、电学性质的影响规律。
结果
2
将介孔活性炭(mesoporous activated carbon,MC)与单分散石墨烯/单壁碳纳米管杂化物(graphene/single-walled carbon nanotube hybrid,GNH)混合,紧密压缩制成锂离子电容器正极材料。GNH均匀地包裹在MC颗粒表面,与MC面对面接触,增大接触面积;而且GNH在MC颗粒之间形成均匀的三维导电网络,提供了快速的电子传导。另外,GNH具有开放结构,会优先吸附电解液离子,与MC界面间存在浓度梯度;同时,GNH具有较高的导电性,与导电性较差的MC界面间存在接触电势差效应。两者共同促使GNH和MC界面之间形成快速的离子和电子双传输路径,促进离子在MC内部的扩散,从而避免了高电流密度下因离子扩散缓慢而造成的容量损失。
结论
2
添加5% GNH提高了倍率性能,并且在不牺牲堆积密度的前提下同时提高质量和体积能量密度。
Objectives
2
The lithium-ion capacitor (LIC) composite cathode materials with both high mass activity and high volume activity were designed.
Methods
2
By scanning electron microscope
transmission electron microscope
Kanta fully automatic specific surface and pore size analyzer
and four-probe tester
the micromorphology
stacking mode
contact mode and interface characteristics between particles were analyzed for the impact of conductivity and electrical properties of composite electrodes.
Results
2
Mesoporous activated carbon (MC) and monodisperse graphene/single-walled carbon nanotube hybrid (GNH) were mixed
followed by compressing tightly to prepare the lithium-ion capacitor cathode material. GNH were uniformly wrapped around the surface of MC particles with face-to-face connection
which increases the contact area. Then
the even 3D conductive network constructed by GNH among the individual MC particles provided high electrical conductivity and accelerated electron conduction. In addition
GNH were located at the high ion concentration side due to their exohedral surface structure. Meanwhile
a contact potential difference effect existed between GNH (the easy conductive one) and MC (the poor conductive one). This produced rapid ion and electron dual transport channels at the interface between GNH and MC
and boosted ion diffusion in the porous structure inside MC particles. It will help avoid the loss of capacity from slow ion diffusion at higher current densities.
Conclusions
2
The addition of 5% GNH brings about outstanding rate performance
and higher mass and volumetric energy density
but does not reduce the packing density.
