Abstract

Among the goals of modern renewable energy systems is to convert the available resources into clean forms of stored energy to alleviate the crisis of fossil fuel exhaustion and oil dependence for energy production. New energy storage and conversion technologies are needed for the development of a cost-efficient renewable energy sources. Materials are the key to fundamental advances in various such energy conversion and storage applications. ln order to meet the challenge of global concerns on pollution and the existing fossil fuels it is important to develop new conversion and storage devices. Especially, materials with unique nanostructures offer exceptional properties or combinations of properties for a wide range of energy devices. This presentation will review/describe some of the recent developments in materials for batteries, supercapacitors, fuel cells, photoelectrochemical cells etc. Novel current and emerging electrode materials and their processing methods for battery technologies based on Lithium, Magnesium, Sodium etc., various carbon/transition metal oxide composite, nitride-based supercapacitors and OER (oxygen evolution reaction) catalysts for advanced air batteries and fuel cells will be presented. The advantages of the nanoscale in materials design for such devices and possible new pathways for improving the strategy of the materials design will be discussed.
