Nanotechnology for Energy Storage and Conversion Applications

Abstract:The high performance, sustainable, and effective energy storage devices are developed to meet the ever-growing energy demand of the world. Nanotechnology, with its distinguishing characteristics such as conductivity and surface area, has the capability to revolutionize the performance of energy storage devices by manipulating the materials at the nanoscale. This article, with a focus on capacitors and batteries, aims to identify the importance of nanotechnology in the development of energy storage devices such as sodium sulfur, redox flow, and lithium-ion batteries. We examine the use of nanomaterials in batteries, including separators, electrolytes, and electrode materials (such as metal oxides and carbon nanotubes). By modifying materials at the molecular level to improve the capacity, charging rates and efficiency, nanotechnology has transformed energy storage and conservation. Important uses include supercapacitors for quick energy release, graphene and carbon nanotubes in lithium-ion batteries to increase energy density, and nano coatings to improve solar cell efficiency and lower heat loss. The development of improved nanostructured materials is being undertaken to tackle issues such as interfacial side reactions. Solid-state batteries and the integration of nanomaterials with artificial intelligence for improved energy storage are two recent advancements that are encouraging for nanotechnology in energy storage, despite ongoing concerns about cost-effectiveness and environmental impact.
