Abstract

The emission of greenhouse gases into the environment due to the use of non-renewable energy sources has become one of the biggest challenges to the world research community. Hence, there is a necessity for the evolution of clean energy sources since the energy demand has exponentially increased globally because of the expansion in the world’s population leading to modernization. Therefore, a substantial amount of research is being implemented to efficiently convert renewable energy and capture it in energy storage devices. One of the gravitating energy storage devices is a supercapattery device made from the battery and capacitor-type electrode materials with tremendous specific energy and power. The current chapter outlines the development and various aspects of supercapattery devices, including the device’s working mechanism, the materials used, the recent advancement, challenges, and future perspectives.
