In article number 1702145, In‐Suk Choi, Youngjin Jeong, Ji‐Hoon Lee, and co‐workers design a new type of mechanically robust electrochemical capacitor for wearable electronics based on all‐carbon‐based self‐supported nanocomposites. By optimizing the architecture of the three‐dimensional nanocomposite structure with activated carbons uniformly embedded in carbon nanotube sheets, outstanding durability...
With the growing demand for wearable electronics, developing new compatible energy systems is a prominent topic of research. Energy systems mounted on wearable electronics should exhibit high cost efficiency, mechanical robustness, and high electrochemical activity. Herein, all‐carbon‐based large‐area nanocomposites for freely deformable electrochemical capacitors are suggested to address these requirements...
Thin, lightweight, stackable, solid-state supercapacitors are in great demand in the electronics industry because of their use in miniaturized devices. Herein, we report a simple and novel strategy to fabricate ultra-thin, lightweight, and stackable symmetric supercapacitors using MnO2-incorporated carbon nanotube (CNT)-web paper. SEM and TEM analyses revealed a uniform nanometer-scale coating of...
Carbon nanotube (CNT) films are very flexible and serve as active materials for lithium-ion batteries (LIBs). Hence, they have high potential as flexible free-standing electrodes for wearable batteries. However, nanocarbon materials such as CNTs and graphene are of limited use as electrodes because they have a large initial irreversible capacity due to the formation of a solid electrolyte interphase...
A lithium sulfur (Li-S) battery is attracting considerable attention as a next-generation, high-performing battery. In response to the great demand for lightweight, high-capacity batteries, persistent efforts have been made to solve Li-S battery problems such as polysulfide shuttling. In particular, it has become important to develop a flexible battery in portable electronics. In this study, a Li-S...
