An asymmetric fiber-shaped supercapacitor (FSC) with roll-type configuration, displaying high power and energy density characteristics, has been fabricated for energy storage in wearable devices. The positive and negative electrodes of the asymmetric FSC consist of polyaniline (PANI) and MoO₃, respectively, and are deposited on a carbon fiber (CF) substrate using a chemical bath deposition method. A polyvinyl alcohol/H₂SO₄ gel is used as electrolyte, which also maintains the CF electrodes in fiber form. The asymmetric PANI//MoO₃ roll-type FSC exhibits a wider potential range than its symmetric PANI//PANI counterpart, resulting in higher energy and power densities. The asymmetric PANI//MoO₃ roll-type FSC shows an energy density of 67.51 µWh/cm³ with a power density of 59.71 mW/cm³ at a current of 10 mA, which is more than twice the energy density of symmetric PANI//PANI roll-type FSC (30.42 µWh/cm³ and 25.12 mW/cm³).

具有卷状结构的不对称纤维状超级电容器（FSC）具有高功率和能量密度特性，已被制造用于可穿戴设备中的能量存储。不对称FSC的正负电极分别由聚苯胺（PANI）和MoO ₃组成，并使用化学浴沉积方法沉积在碳纤维（CF）基底上。聚乙烯醇/ H ₂ SO ₄凝胶用作电解质，它也使CF电极保持纤维形式。非对称的PANI // MoO ₃辊式FSC比其对称的PANI // PANI具有更宽的电位范围，从而具有更高的能量和功率密度。不对称PANI // MoO ₃辊式FSC在10 mA电流下的能量密度为67.51 µWh / cm ³，功率密度为59.71 mW / cm ³，是对称PANI // PANI辊式FSC（ 30.42 µWh / cm ³和25.12 mW / cm ³）。
