Hydrogels: Promising Energy Storage Materials

摘要

Energy is essential for the economic growth of any country. There is a strong demand for the development of materials that can show potential towards higher power density and energy density. In this article, a promising class of polymeric materials, hydrogels have been discussed as an energy storage material. The hydrogels are advantageous as they possess in them the unique combination of organic conductors and conventional polymers. The article covers the synthetic approach of hydrogels which includes both the conventional synthesis and the new routes adopted followed by the application of hydrogels as energy storage materials. Finally, the future opportunities and prospects in the development of hydrogels as advanced energy storage materials are highlighted.
