An asymmetric supercapacitor (ASC) was assembled by using an activated carbon as positive electrode and WO3 nanowire as negative electrode, and its electrical performances were tested in voltage windows ranging from 0 to 1.5 V. A high specific capacitance of 51 F•g−1 could be achieved at the current density of 0.25 A•g−1. Moreover, the ASC displays a good cycling stability with 86% of capacitance retention after 800 cycles, its energy density can be up to 11.9 Wh•kg−1 at the power density of 210 W•kg−1, and remains 7.7 Wh•kg−1 at a po...

不对称的 supercapacitor (ASC ) 被作为否定电极把激活的碳用作积极电极和 WO 3 nanowire 装配，并且它的电的表演在从 0 ～ 1.5  V 的电压窗口中被测试。51  F•g −1 的一个高特定的电容能在 0.25 A•g −1 的当前的密度被完成。而且， ASC 在 800 个周期以后与 86% 电容保留显示好骑车稳定性，它的精力密度能直到在 210  W•kg −1, 和遗体的力量密度的 11.9  Wh•kg −1 在 1250  W• kg 的力量密度的 7.7  Wh•kg −1−1 。优秀电的表演也许由于水晶取向(001 ) 为 WO 3 nanowire 的飞机...
