In our rapidly evolving society, electricity demand continues to surge with the proliferation of electromobility, mobile devices, and the Internet of Things. As we shift towards renewable energy sources, the need for efficient energy storage solutions becomes paramount. While lithium-ion batteries have dominated the field, carbon-based supercapacitors offer a compelling alternative with their safety, longevity, and rapid charging capabilities. Our recent breakthrough introduces a nitrogen superdoped graphene material, featuring diamond-like interlayer bonds, to address the longstanding challenge of limited energy density in supercapacitors. By significantly boosting the energy content per volumetric unit of the electrode, our material achieves unprecedented energy densities, surpassing those of conventional supercapacitor carbons and paving the way for enhanced supercapacitor performance in various applications.
