The globe is currently dealing with an energy crisis, which is very
concerning. While energy accessibility and availability have a significant impact on
human well-being, the world's dependence on alternative energy sources is growing as
a result of the ongoing depletion of fossil fuels. Scientists are developing other
sustainable energy sources so that we can meet future energy needs and live in a
cleaner environment. In the natural environment, excitation energy transfer is the
principal procedure for the light-harvesting procedure. In recent years, transition metal
complexes have been used in many applications, such as electroluminescent materials,
photoinduced energy transfer materials, energy storage materials, and organic
photovoltaic materials. Additionally, these materials provide the potential to behave as
carbon sinks, hence providing a chance for more storage materials that are sustainable.
For years, the electrochemical behavior of transition metal complexes has been
explored in devices that store energy, such as redox flow batteries, supercapacitor
electrodes, sodium-ion batteries, and lithium-ion batteries. In this chapter, various
transition metals and other metal complexes that are utilized as energy materials are
highlighted.
