0D to 3D carbon-based networks combined with pseudocapacitive electrode material for high energy density supercapacitor: A review

Supercapacitors are considered reliable devices for energy storage. However, supercapacitor has some limitations, such as relatively low capacitance and low energy density, which affect it as a promising energy storage device. In this context, carbon based nanocomposites have been widely studied in the past few years due to their excellent physical, mechanical and electrical properties. A lot of studies have been reported on carbon based materials with different 0D, 1D, 2D and 3D carbon nanostructures. The unique combination of pseudo-material with carbon material greatly improves the electrochemical performance of the composite as compared to individual candidate. However, developing high energy density supercapacitor devices with high cycling stability in a simple and cost effective way is still a challenge. This review provides the current progress on the carbon based pseudo-material composites for supercapacitor application in a well-systematic and easy manner which can guide the early researchers and emerging scientists dealing with or interested in supercapacitor.

Automated summary

Supercapacitors are reliable energy storage devices, but face limitations such as low capacitance and energy density. Carbon based nanocomposites have been extensively studied for their excellent properties. Developing high energy density supercapacitor devices remains a challenge despite advancements in research.
