Supercapacitors: The Innovation of Energy Storage

Abstract

In addition to the accelerated development of standard and novel types of rechargeable batteries, for electricity storage purposes, more and more attention has recently been paid to supercapacitors as a qualitatively new type of capacitor. A large number of teams and laboratories around the world are working on the development of supercapacitors, while their ever-improving performances enable wider use. The major challenges are to improve the parameters of supercapacitors, primarily energy density and operating voltage, as well as the miniaturization, optimization, energy efficiency, economy, and environmental acceptance. This chapter provides an overview of new techniques and technologies of supercapacitors that are changing the present and future of electricity storage, with special emphasis on self-powering sensor and transmitter systems. The latest achievements in the production, modeling, and characterization of supercapacitor elements (electrode materials, electrolytes, and supporting elements) whose parameters are optimized for long-term self-supply of low power consumers (low voltage, high energy density, and low leakage current, etc.) are considered.

“…The energy and climate crisis alongside the increase in energy consumption and understanding of environmental challenges have enforced the demand for sustainable development of clean and high-performance materials for energy storage applications [ 1 ]. Among the different energy storage device configurations available, supercapacitors are energy storage devices with outstanding properties, such as fast charge/discharge rates, superior power density, and extended cycle life [ 2 ]. The electrode materials and the electrolyte play an essential role in the energy storage system performance of the supercapacitors.…”

“…The escalating demand for energy storage technologies, driven by the rapid proliferation of portable electronics, electric vehicles, and renewable energy systems, necessitates the development of efficient, durable, and environmentally friendly supercapacitors. Supercapacitors are known for their high power density and long cycle life, they play a pivotal role in bridging the gap between the conventional capacitors and batteries which have landed themselves in energy storage application in a wide range of devices especially for portable devices [1,2]. However, supercapacitors have low energy density because of which there is limitation of its use in energy backup.…”
