In article number 2000372, Bo Hou, Gehan A. J. Amaratunga, and co‐workers present asymmetric carbon nanohorns as an active material to fabricate flexible solid‐state carbon wire‐based electrochemical supercapacitors, which exhibit remarkable specific length capacitance and charge‐discharge stability. Furthermore, a high‐pass filter for eliminating ultra‐low electronic noise is demonstrated, which enables an optical Morse Code communication system to be operated.
