一篇AEM上新出的超级电容器的文章~？最近的一篇电容器文章~ Graphitic Petal Electrodes for All-Solid-State Flexible Supercapacitors在碳布上长花瓣状 石墨烯 ~ 石墨烯上负载PANI，大大提高了容量而且做成了固态电容器，性能很棒！http://[/img]Abstract:The charge storage characteristics of a composite nanoarchitecture with a highly functional 3D morphology are reported. The electrodes are formed by the electropolymerization of aniline monomers into a nanometer-thick polyaniline (PANI) film that conformally coats graphitic petals (GPs) grown by microwave plasma chemical vapor deposition (MPCVD) on conductive carbon cloth (CC). The hybrid CC/GPs/PANI electrodes yield results near the theoretical maximum capacitance for PANI of 2000 F g?1 (based on PANI mass) and a large area-normalized specific capacitance of ≈2.6 F cm?2 (equivalent to a volumetric capacitance of ≈230 F cm?3) at a low current density of 1 A g?1 (based on PANI mass). The specific capacitances remain above 1200 F g?1 (based on PANI mass) for currents up to 100 A g?1 with correspondingly high area-normalized values. The hybrid electrodes also exhibit a high rate capability with an energy density of 110 Wh kg?1 and a maximum power density of 265 kW kg?1 at a current density of 100 A g?1. Long-term cyclic stability is good (≈7% loss of initial capacitance after 2000 cycles), with coulombic efficiencies >99%. Moreover, prototype all-solid-state flexible supercapacitors fabricated from these hybrid electrodes exhibit excellent energy storage performance.DOI:10.1002/aenm.201300515查看更多1个回答 . 27人已关注
