摘　　要：Aluminum electrolyte capacitors(AEC)are widely used in AC filtering as traditional filter capacitors.However,their strong rigidity,high hardness,and high-risk factor have hindered the flexible development of filter capacitors.Flexible supercapacitors,due to their high energy density and outstanding cycle stability,are becoming one of the main directions for the development of filter capacitors in the future.This paper self-assembles a MnO_(2)-based flexible supercapacitor with high area capacitance and fast frequency response,and preliminarily verifies the feasibility of using the capacitor for AC filtering through simulation tests in Multisim.Finally,the AC filtering test of the flexible supercapacitor using an oscilloscope demonstrates that the ripple factor in the range of 2.7%to 8%,which confirms that the MnO_(2)-based flexible supercapacitor has a great AC filtering function and can replace traditional aluminum electrolyte capacitors in AC filtering,promoting the flexible development of electronic products.
