AbstractThe rapid growth of wearables has created a demand for lightweight, elastic and conformal energy harvesting and storage devices. The conducting polymer poly(3,4-ethylenedioxythiophene) has shown great promise for thermoelectric generators, however, the thick layers of pristine poly(3,4-ethylenedioxythiophene) required for effective energy harvesting are too hard and brittle for seamless integration into wearables. Poly(3,4-ethylenedioxythiophene)-elastomer composites have been developed to improve its mechanical properties, although so far without simultaneously achieving softness, high electrical conductivity, and stretchability. Here we report an aqueously processed poly(3,4-ethylenedioxythiophene)-polyurethane-ionic liquid composite, which combines high conductivity (>140 S cm−1) with superior stretchability (>600%), elasticity, and low Young’s modulus (<7 MPa). The outstanding performance of this organic nanocomposite is the result of favorable percolation networks on the nano- and micro-scale and the plasticizing effect of the ionic liquid. The elastic thermoelectric material is implemented in the first reported intrinsically stretchable organic thermoelectric module.

The possibility of both energy and environmental crisis that may arise due to use of fossil fuels has resulted in intense research activities in the past decade on the development of technologies for harvesting and storage of energy from renewable sources. In order to meet the energy requirements for an ever-increasing population, there is a need for high performance electrochemical energy harvesting as well as storage devices. Nanomaterials and nanocomposites with diverse composition, structure, and morphologies have been applied in various energy related applications ranging from photocatalytic hydrogen generation, solar electricity generation, electric energy storage by lithium ion batteries and supercapacitors, hydrogen storage systems, etc. The aim of this chapter is to provide an overview of the recent developments in the technological advancements brought about by the use of nanotechnology in energy harvesting and storage appliances with specific focus on dye sensitized solar cells for electricity generation, lithium ion batteries, and supercapacitors for energy storage.

Long-length nanofibers are able to form porous networks with high surface-area-to-volume ratios, and decrease diffusion lengths. While there are numerous techniques to create nanostructures, electrospinning is the only technique that allows fabrication of nanofibers at long-length scales. These uniquely shaped fibers are applied to several energy-related devices. This review is an in-depth summary of the uses of electrospun fibers in dye-sensitized solar cells (DSSCs), batteries, capacitors, fuel cells, and hydrogen storage devices. Developments in electrospinning technologies to create novel fiber morphologies are also discussed.
