the charge separation at the electrode/ electrolyte interface, and (b) the reversible faradaic reaction where the pseudocapacitance arises from reversible faradic reaction occurring at the electrode/electrolyte interface. [6][7][8] Among various electrode materials, conducting polymers such as polypyrrole (PPy) and polyaniline (PANI), [9][10][11] are receiving specifi c attentions due to their intrinsic characteristics including low cost, easy preparation, remarkable storage capacity, good conductivity, and broad voltage window. [12][13][14][15] Basically, the utilization of conducting polymers as electrode materials usually shows a considerable enhancement in specifi c energy density, but those electrodes may exhibits a poor cycling stability due to serious volumetric swelling and shrinking of conducting polymers during cycles. [16][17][18][19] An emerging solution to overcome the challenges facing conducting polymers including poor electroactive stability and weak mechanical properties is to grow conducting polymers on the surfaces of various supporting materials such as graphene, metal oxides, metal dichalcogenide, etc. [20][21][22][23][24][25] The superiority of using those supporting materials is evident because they can offer a uniform and large-surface-area substrate to immobilize conducting polymers for effi cient energy storage. [ 26,27 ] Molybdenum disulfi de (MoS 2 ) is a typical 2D layered transition metal dichalcogenide which possesses unique structure features with large interlayer distance of 1.24 Å, high electrochemical activity, and good chemical stability. Therefore, MoS 2 has become a particularly promising candidate for applications in supercapacitors [28][29][30] and lithium ion batteries. [31][32][33] Meanwhile, the weak van der Waals interaction and relative large interlayer distance between MoS 2 layers facilitates the intercalation of positive ions (H + , K + , and Li + ), resulting in enlarged effective surface area which could be used as a 2D template for growing conducting polymers or other functional nanoparticles. [34][35][36][37][38][39][40] Herein, we developed a simple and effi cient strategy to construct MoS 2 /PPy/PANI ternary hybrids via two successive polymerizations of PPy and PANI on few-layer MoS 2 (f-MoS 2 ) templates. Surprisingly, a rational design of such ternary nanocomposites enables greatly improved specifi c capacitance as Polypyrrole (PPy) and polyaniline (PANI) are most promising candidates for high energy and power density supercapacitors. However, their relative low surface area and poor cyclic stability greatly limit their practical applications. Morphology-and size-controlled micro/nanostructure formation of such materials may lead to enhanced performance. Here, the solvent-exchange method is proposed for the preparation of high-concentration few-layer MoS 2 (f-MoS 2 ) suspension in an ethanol-water mixed solvent. PPy layers with high surface coverage are formed on the resultant dispersible f-MoS 2 by in situ polymerization of pyrrole. The MoS 2 /PPy hybrid is...

With the continuous progress of the energy use and demand, functionalized energy storage and conversion devices (ESCDs) are urgently needed. In the meantime, stretchable ESCDs are attracting intensive attention due to their great potential for specific applications, such as wearable electronics, an electronic skin, implant electronics, and other collapsible gadgets. Design and synthesis of nanomaterials are at the core in the development of highly stretchable supercapacitors, batteries, and solar cells for such applications. This chapter first provides a brief summary of research development on the stretchable ESCDs in the past decade through various strategies of device design and manufacturing approach. After that, the focuses are on the advanced engineering of nanomaterials as active materials to achieve the stretchability of these ESCDs while maintaining a stable and functional performance. Finally, some of the challenges and the important directions in the areas of design and synthesis of nanomaterial facing the stretchable ESCDs are discussed concisely. IntroductionWith the rapidly increasing population and economic development, the world's energy consumption is escalating dramatically, resulting in one of the most serious global challenges of our time-energy scarcity. Hence, a crowd of research in the areas of advanced technologies for energy storage (e.g., batteries and supercapacitors) and conversion (e.g., solar cells) during the past decade has been driven by the

Stretchable energy storage devices are essential for the development of stretchable electronics that can maintain their electronic performance while sustain large mechanical strain. In this context, stretchable supercapacitors (SSCs) are regarded as one of the most promising power supply in stretchable electronic devices due to their high power densities, fast charge-discharge capability, and modest energy densities. Carbon materials, including carbon nanotubes, graphene, and mesoporous carbon, hold promise as electrode materials for SSCs for their large surface area, excellent electrical, mechanical, and electrochemical properties. Much effort has been devoted to developing stretchable, carbon-based SSCs with different structure/performance characteristics, including conventional planar/textile, wearable fiber-shaped, transparent, and solid-state devices with aesthetic appeal. This review summarizes recent advances towards the development of carbon-based SSCs. Challenges and important directions in this emerging field are also discussed.
