The reduction of internal resistance in supercapacitors is essential for storing and delivering a large amount of energy at high speed. In article number 1500354, H. Nakanishi and co‐workers have developed all‐metal monolithic nanowire array supercapacitor electrodes that allow for ultrafast charge/discharge rates of up to 300 V s −1 . Defects in nanowire arrays greatly influence device performance. Supercapacitor electrodes prepared from defect‐free molds lower the internal resistance, providing superior performance at higher energy and power densities.
