Energy storage devices have acquired great research attention in the fabrication of ultra-high efficient supercapacitors. In order to enhance the electrochemical performance of the supercapacitors, different electrodes have been fabricated using various nanomaterials with precisely controlled morphologies and interfaces. Nevertheless, the low-dimensional nanomaterials still suffer from the factors such as severe re-stacking, non-homogeneous aggregation, and low contacts during the processing and assembly. These bottle-neck problems essentially lead to the hindrance of transport of electrons and/or ions in the energy devices. In this direction, recently, the bioinspired nanomaterials are emerging as the potential candidates to overcome the said disadvantages of the chemically derived low dimensional nanomaterials. The well-aligned or highly oriented bioinspired nanostructures found to effectively promote the transport of electrons, facilitate the ion diffusions through the hierarchical pores and provide the large specific surface area for their interfacial interactions with the surroundings. Moreover, the nanoscale materials can be easily tuned or engineered for their physicochemical properties, thereby they can be potentially used in many device applications. In this context, this chapter is intended to highlight the recent progress in bioinspired nanomaterials towards developing the electrode materials for supercapacitors with the emphasize on the fundamental understandings between their structural properties and electrochemical performances. Finally, it concludes with an outlook on the next generation nanostructured electrodes to design the ultra high-efficient supercapacitors.
