Basics and Architectural Aspects of Flexible Energy Devices

Abstract

Flexible technologies, such as those dealing with conversion energy harvesting and storage, have been recognized as a promising factor for enhancing our everyday lives. The performance of the flexible devices depends on the flexible nature of the device; therefore, developing advanced materials and technology is very important. Several recent advances in flexible devices (supercapacitors, batteries, solar cells) constituents, such as solid-state electrolytes or electrodes, have consolidated the foundation for flexible energy conversion and storage devices. Despite making significant progress in this field, many fundamental and technical challenges impede the practical exploitation of flexible energy devices. The main goal of this chapter is to explore flexible devices phenomena, prevailing in charge transport in the aforementioned systems, and provide novel strategies to the design and fabrication of new components. In addition, the chapter discusses the key problems that remain open in this area. This chapter also addresses the challenges in technologies for wearable, stretchable, and flexible energy devices.
