英文摘要	Aluminum electrolytic capacitors (AECs) are widely used for alternating current (ac) line-filtering. However, their bulky size is becoming more and more incompatible with the rapid development of portable electronics. Here we report a scalable process to fabricate miniaturized graphene-based ac line-filters on flexible substrates at room temperature. In this work, graphene oxide (GO) is reduced by patterned metal interdigits at room temperature and used directly as the electrode material. The as-fabricated device shows a phase angle of -75.4 degrees at 120 Hz with a specific capacitance of 316 mu F/cm(2) and a RC time constant of 0.35 ms. In addition, it retains 97.2% of the initial capacitance after 10000 charge/discharge cycles. These outstanding performance characteristics of our device demonstrate its promising to replace the conventional AECs for ac line filtering.; Advanced Research Project Agency- Energy (ARPA-E) program [DE-AR0000303]; National Natural Science Foundation of China [11272008, 11361161001]; Chinese Scholarship Council [201206010240]; SCI(E); PubMed; ARTICLE; cp.wong@mse.gatech.edu; slbai@pku.edu.cn; 10983; 5
