Thin film supercapacitors were fabricated using printable materials to make flexible devices on plastic. The active electrodes were made from sprayed networks of single-walled carbon nanotubes (SWCNTs) serving as both electrodes and charge collectors. Using a printable aqueous gel electrolyte as well as an organic liquid electrolyte, the performances of the devices show very high energy and power densities (6 W h/kg for both electrolytes and 23 and 70 kW/kg for aqueous gel electrolyte and organic electrolyte, respectively) which is comparable to performance in other SWCNT-based supercapacitor devices fabricated using different methods. The results underline the potential of printable thin film supercapacitors. The simplified architecture and the sole use of printable materials may lead to a new class of entirely printable charge storage devices allowing for full integration with the emerging field of printed electronics.
使用可印刷材料制造薄膜超级电容器，以便在塑料上制作柔性器件。活性电极由作为电极和电荷收集器的单壁碳纳米管（SWCNT）喷涂网络制成。使用可印刷的水性凝胶电解质以及有机液体电解质，该器件的性能显示出非常高的能量和功率密度（两种电解质均为6 W h/kg，水性凝胶电解质和有机电解质分别为23和70 kW/kg），这与使用不同方法制造的其他基于SWCNT的超级电容器器件的性能相当。结果突出了可印刷薄膜超级电容器的潜力。简化的架构和可印刷材料的单一使用可能会带来一类全新的完全可印刷的电荷存储器件，实现与新兴的印刷电子领域的完全集成。
