Stepping into the Internet of Things (IoT) era, widely-distributed electronics with connected mobility are changing our living way in personalized healthcare, seamless communication, smart society, and many others. In that case, the number of distributed electronics is booming at a skyrocketing rate. To drive these distributed electronics, a pervasive power supply system featuring low-cost and environmentally friendly is highly desired. Recently, a low-cost, easy-fabricating, and air-stable conducting polymer (CP) ink have been successfully demonstrated by Prof. Weiqing Yang and Haitao Zhang’s group, which have been featured as a cover article on famous academic journal Small. This CP ink exhibits a high conductivity in the order of 10-2 S cm-1 along with a remarkable specific capacitance of 386.9 F g-1 at 0.5 A g-1 (dehydrated state). The printable MSC derived from as-prepared CP ink delivers high areal capacitance of 96.6 mF cm-2, large volumetric capacitance of 26.0 F cm-3 as well as considerable energy density of 2.4 mWh cm-3 at 238.3 mW cm-3, surpassing the majority of state-of-the-art MSCs derived from pseudocapacitive materials. This work is proposed to provide a cost-effective, environmentally friendly, and pervasive energy solution that underpins wearable and portable electronics in the IoT era.
